Title: Development of a Data Acquisition System for the Belle II
Silicon Vertex Detector
Abstract content
The Silicon Vertex Detector (SVD) is one of the main detectors in the Belle II experiment (KEK, Japan) which takes essential roles in the decay-vertex determination, low-energy-track reconstruction, and background rejection. The SVD consists of four layers of Double-sided Silicon Strip Detectors (DSSD) and is being developed toward the start of the Belle II experiment in 2016.
Due to more than 220,000 strips in the whole SVD and the Belle II maximum trigger rate of 30 kHz, the integration of a large number of readout channels and the reduction of data size are challenging issues on the development of the SVD readout electronics. APV25 chips are employed to read the DSSD signals, and Flash-ADC (FADC) boards digitize and decode the outputs of the APV25s. To increase the integration density of the readout channels, one FADC board processes 48 APV25 outputs with one FPGA. The FPGA performs pedestal-subtraction, two-step common-mode correction, and zero-suppression for the sake of the data reduction.
The development of the first prototype of the SVD readout system was completed in Dec. 2013, and the performance study of this system was done in an electron beam at DESY in Jan. 2014. In the beam test, the prototype system was implemented into the Belle II DAQ for the first time and the whole data-streaming was successfully operated.
In this presentation, we will introduce features of the SVD readout system, and report on prototype performance results from the beam test, as well as future prospects for the Belle II experiment.

Title: Construction and test of high precision drift-tube (sMDT)
chambers for the ATLAS muon spectrometer
Abstract content
For the upgrade of the ATLAS muon spectrometer in March 2014 new muon tracking chambers (sMDT) with drift-tubes of 15 mm diameter, half of the value of the standard ATLAS Monitored Drift-Tubes (MDT) chambers, and 10 $\mu m$ positioning accuracy of the sense wires have been constructed.
The new chambers are designed to be fully compatible with the present ATLAS services but, with respect to the previously installed ATLAS MDT chambers, they are assembled in a more compact geometry and they deploy two additional tube layers that provide redundant track information.
The chambers are composed of 8 layers of in total 624 aluminium drift-tubes.
The assembly of a chamber is completed within a week.
A semi-automatised production line is used for the assembly of the drift-tubes prior to the chamber assembly.
The production procedures and the quality control tests of the single components and of the complete chambers will be discussed.
The wire position in the completed chambers have been measured by using a coordinate measuring machine and cosmic ray muons tracks in a test stand with two MDT reference chambers.
Summary
New high precision drift-tube chambers with a tube diameter of 15 mm, a factor of two smaller than the standard Monitored Drift-Tube (MDT) chambers, have been developed for the upgrade of the ATLAS muon spectrometer in the 2013-2014 shutdown of the Large Hadron Collider at CERN.
The new chambers consist of 624, 2.2 m long, aluminium drift tubes deployed in 8 layers, for a total with a width of 1.2 m, and an accuracy of 10 $\mu$m in the positioning of the sense wires.
The new chambers operate with the same Ar:CO$_2$ (93:7) gas mixture at 3 bar pressure and the same read-out electronics as the present chambers.
The tube layers with 78 drift tubes each are arranged in two multi-layers of 4 tube layers separated by a spacer frame containing an optical alignment system which monitors deformation with few micron precision. The smaller tube diameter allows for more tube layers and, therefore, more tracking redundancy and for about a factor 10 higher rate capability in the neutron and gamma ray environment of the ATLAS muon spectrometer.
Extensive quality control tests are employed to ensure the high reliability of the detector.
The drift tubes are assembled and tested prior to the chamber construction using semi-automated wiring and testing stations where the wire tension, HV leakage current and gas leak rate of each drift tube are measured, quality controlled, and stored in a database. The chamber is then assembled with a procedure that allows to complete a 4 layer sub-section of the chamber in less than two working days.
After the assembly the geometry of the chamber is tested using a precision 3D-position measurement machine and a cosmic ray test facility with two MDT reference chambers with precisely known wire position and geometry.

Title: A real x-y microbulk Micromegas with segmented mesh
Abstract content
We present for a first time, the development of Micromegas detectors based on Microbulk technology with segmented mesh. The space charge produced within the amplification volume induces both signals and the mesh strips provide the y coordinate while the anode strips the x coordinate. The manufacturing of a segmented mesh simplifies the x-y readout that up to now was produced in a complicated and delicate way due to the x-y strips formation (x-pads link in the front and y-pads link via through holes in the back plane) and had a high risk of deteriorating the detector quality or even damaging the detector in the last stages of construction. This R&D is a project supported by the RD51 collaboration. The design and manufacturing has been optimized and produced segmented mesh Microbulk Micromegas with excellent properties in Energy resolution, stability and good position resolution. We have designed appropriate FE-electronics for providing the bias HV to every individual mesh strip and reading it out. The design aims to an ultra low background, ultra low threshold detector appropriate for rare event searches, thanks to its low material budget that may further improve the excellent Microbulk technology background properties close to ~(few)x10-7 cnts/keV/cm2/s. We will present details of the design and the manufacturing of the segmented mesh microbulk, results on the detector performance, prospects for further improvements and possibilities that open for rare processes, neutron detection and other applications. We believe that this design constitutes a break-through in the Micro Pattern Gaseous Detectors developments.

Title: Sharing high speed optical data transmission links with Slow
Control stream
Abstract content
An unified overall readout and optical high speed data transmission, called Belle2link, has been designed for use between Front-End electronics of all sub-detectors and the backend data acquisition in the Belle II experiment at KEK, Japan. These links provide not only a good electrical isolation, but also a bidirectional centralized data collection and command distribution. Further more the capacity of the gigabit fiber is far more than be needed, which stimulated us a idea to share the high speed data link with the slow control function(detector parameters setting). In addition to the description of belle2link in TIPP2011, this talk describes in detail about the relization of this slow control, including parameter setting in frontend electronics, combining slow control data in FE part with and separating slow control data in BE part from detector physics data, data priority management, single command mode and batch commands mode implementation. Tests made with drift chamber and silicon vertex detector systems are provided together with results and discussions.
Summary
The Belle2link, an unified overall readout with optical high speed data transmission shared with slow control functionality of detector parameter control has been designed for the Belle II experiment at KEK, Japan. A model system based on drift chamber system was successful and tt has been accepted by the collaboration. System for Drift Chamber had passed with cosmic ray test and beam test, system for Silicon Virtex Detector is now under beam test at DESY, Germany which showed also a success. Implementation and tests to other systems are under going.

Title: Impact of Low-Dose Electron Irradiation on the Charge
Collection of n+p Silicon Strip Sensors
Abstract content
The response of p+n strip sensors to electrons from a 90Sr source and focussed laser light with different wave lengths was measured using the ALiBaVa read-out system. The measurements were performed over a period of several weeks, during which a number of operating conditions were varied. The sensors were fabricated by Hamamatsu on 200 µm thick float-zone silicon. Their pitch is 80 µm, and both p-stop and p-spray isolation of the p+n strips were studied.
The electrons from the 90Sr source were collimated to a spot with a full-width-at-half maximum of 1.8 mm at the sensor and the dose rate at the maximum in the SiO2 was about 0.6 mGy/s. The estimated dose at the end of the measurements was about 1 kGy in SiO2. In addition, test structures (pad diodes, MOS capacitors with and without p-stop and p-spray implants, and gate-controlled diodes) fabricated together with the sensors, were investigated for X-ray doses of up to 1 kGy in SiO2 in order to determine technological parameters and their dependencies on X-ray dose.
As function of irradiation time with the 90Sr source significant changes in charge collection and charge sharing are observed. Annealing studies with temperatures up to 80°C have shown that the observed changes are only partially reversed. The observations are qualitatively explained with the help of TCAD simulations. The relevance of the measurements for the design and the use of p+n strip sensors in different radiation environments are discussed.

Title: Development of a Muon Polarimeter for the T-violation Search
Experiment at J-PARC
Abstract content
TREK is a precision-frontier experiment, planned at J-PARC (Tokai, Japan), for a T-violation search in Kaon decays into the pi0 mu+ nu final state. The signature is a non-zero transverse polarization (P_T) of muons in the direction perpendicular to the decay plane. Using the same process the E246 experiment at KEK has set an upper limit on | P_T | < 0.0050 at the 90% confidence level. TREK is an upgrade of E246 with the goal of achieving more than a factor of 20 higher sensitivity using high intensity Kaon beam from J-PARC and the detector with major upgrades that include a new GEM tracker, new photon device for the CsI(Tl) calorimeter and a new magnet system providing uniform field. The most important element of TREK is the new muon polarimeter of novel design, incorporating an active muon stopper instrumented by an array of drift tubes for tracking. This design allows the tracks of muons and positrons to be reconstructed, providing a large acceptance for positrons with higher analyzing power, background suppression, and handles for controlling systematic uncertainties such as those arising from uncertainty on the decay position and its distribution. We present an overview of the TREK experiment and detail of the muon polarimeter R&D with results of studies using Monte Carlo simulation and beam tests of the full size prototype.

Title: High granularity scanner for MPGD based photon detectors
Abstract content
Gaseous detectors can be made sensitive to photons, and become excellent choice for applications such as Cherenkov radiation imaging for particle identification. Micopattern Gaseous Detector (MPGD) technologies opened new ways to photon detection, where the possibility for reduced ion feedback, better timing and the suppression of non-photon signals are factors of improved performance. On the other hand the microstructure of an MPGD renders the photo-electron emission, transfer and subsequent detection to be a very complex process.
We have developed a high resolution UV photon scanner, where single photon-electron response measures local detection efficiency and gas gain with position resolution better than 100 microns. Studies on Thick GEM based photon detectors proved the existence of inefficient symmetry points, and shed light on hole-gain structure and microscale variance. In fact practically all MPGD detectors, even if not designed for photon detection in the first place, can be made sensitive, and thus be explored, by the scanning system. Measurement of the microsturcture of the charge transport can lead to a better understanding of the detection mechanisms, and help in optimization of various MPGD, especially for Cherenkov detectors.
The presentaion will focus on details of the critical parts of such a system; and recent results on TGEM microstructure with its dependence on the applied micropattern configurations.

Title: The Atlas SCT operation and performance
Abstract content
We report on the operation and performance of the ATLAS Semi-Conductor Tracker (SCT), which has been functioning for 3 years at the Large Hadron Collider at CERN. The SCT is constructed of 4088 silicon detector modules. We find 99% of the 6.3 million strips are operational, the noise occupancy and hit efficiency exceed the design specifications; the alignment is very close to the ideal to allow on-line track reconstruction and invariant mass determination. We will report on the operation and performance of the detector including an overview of the issues encountered. We observe a significant increase in leakage currents from bulk damage due to non-ionizing radiation which is in agreement with the predictions.We will also cover the time evolution of the key parameters of the strip tracker, including the evolution of noise and gain, the measurement of the Lorentz angle and the tracking efficiency in the harsh LHC environment. Valuable lessons for future silicon strip detector projects will be presented.
Summary
We propose a talk that summarizes the data-taking operations of the ATLAS Semi Conductor Tracker at the LHC, including the main difficulties we had to cope to, namely the failure of the optical transmitter on the readout board and the higher current of a subset of sensors.
We have an updated determination of the radiation damage and we can show the performance of the SCT during tha LHC Run-1. The activities during the shutdown consist mostly in increasing the number of readout boards, to cope with a higher trigger rate.

Title: Experimental results for the Cherwell 1 and 2 MAPS sensors
Abstract content
We report on the status and performance of the CMOS Monolithic Active Pixel Sensor (MAPS) Cherwell 1 and 2 sensors for the detection of charged particles in vertexing, tracking, and calorimetry applications. Cherwell is a 4-T CMOS sensor in 180 nm technology on a 12um epitaxial substrate with low-noise, low-power, in-pixel correlated double sampling, and high conversion gain.
Cherwell 1 consists of four arrays, two optimized for vertexing and tracking applications, and two for digital calorimetry applications. The vertexing arrangements have a matrix of 96x48 pixels with a pitch of 25 um. The “reference array” is readout on a rolling shutter base with a fine resolution 12-bit, single-slope column parallel ADC. The “strixel" array has the readout and ADC circuits embedded in the space between the pixel diodes. The two sections for calorimetry have a matrix of 96x48 pixels with 25 um pitch and 48x24 pixels with 50 um pitch, respectively. Additional circuitry is added to provide charge summing of 2x2 pixels during readout.
Cherwell 2 is a prototype candidate sensor to be used in the upgrade of the ALICE Inner Tracker System at the LHC. It has three variants of a 128x128 pixel array on a 20um pitch using the strixel technology.
We report on the characterisation and performance of the prototypes, on the test bench and at the test beam.

Title: Development of Superconducting Tunnel Junction Photon Detectors
as a far-infrared single photon detector for neutrino decay search
Abstract content
We present the development of Superconducting Tunnel Junction (STJ) detectors as far-infrared single photon detector motivated by application to a search for radiative decay of cosmic background neutrino. The photon energy spectrum from the neutrino radiative decays is expected to have a sharp edge at high energy end in a far-infrared region ranging from 14meV to 25meV (from 50um to 90um in wavelength). We explore the the cosmic infrared background photon energy spectrum in this region for feeble contribution from neutrino decays. Thus, the detector is required to measure photon-by-photon energies with high resolution enough to identify the edge structure, and designed for a rocket or satellite experiment.
One of our choices for the detector is STJ using hafnium (Hf-STJ) which is expected to have 2% energy resolution for single photon of 25meV due to very small gap energy of hafnium. Another choice for the detector is a combination of the diffraction grating and array of niobium-aluminum STJ (Nb/Al-STJ) pixels, where each Nb/Al-STJ pixel is capable of single photon detection for
a far-infrared photon delivered to each pixel according to its wavelength by the grating. For the Hf-STJ development, we have successfully produced a superconducting-insulator-superconducting structure using hafnium, that is confirmed by Josephson current, and observed a response to visible light illumination, although much higher leak current than its requirement is a
major issue to be resolved. For the Nb/Al-STJ, it is also challenging that an amplifier at extremely low noise level of 10 electron-equivalent-noise is required.

Titre: HARPO - TPC for High Energy Astrophysics and Polarimetry from
the MeV to the TeV
Abstract content
Observation of high-energy sources requires gamma-ray telescopes aboard balloons or satellites to study thermal and non thermal phenomena (black holes, neutron stars, active galactic nuclei, supernovae, supernova remnants, and gamma-ray bursts). In recent years, R&D has been mainly active to improve the sensitivity required for polarimetry. In this context, a concept of a Time Projection Chamber (TPC) was proposed as an active target and pair production imager with a high angular resolution and background reduction capabilities.
After introducing the HARPO TPC and its potential as gamma-ray telescope, we will present the characterization of the TPC readout plane which provides gas electron amplication within a microstructure composed of the association of a Micromegas and Gas Electron Multiplier. Recent results using cosmic-ray events will be shown and nally the beam test, scheduled this year, with polarized photon at MeV energy will be discussed.

Title: zig-zagging CO2 evaporation cooling system R&D
Abstract content
Design, prototype production and thermal test of a new cooling system for the the Upgrade of the UT Tracker for LHCb, based on vertical not straight CO2 boiling channels at about -30 °C.
Summary
Proposing a new cooling system for the the Upgrade of the UT Tracker for LHCb, emerged a design with a zig-zagging routing for the CO2 evaporative cooling. This is needed to satisfy the power dissipation extraction requirements dictadìted by the use of powerful read-out chips. The strip tracker detector silicon sensors need to be maintained at operating temperature of -5 °C, the genrated thermal power is about 3800 W. The investigated solution looks at two stave design: one using straight pipes embedded in carbon foam and making use of high conductivity TPG inserts put trought the insulation layers to improve the thermal performance; the other, more efficient solution from the thermal point of view, envisages a "snake" cooling pipe embedded in carbon foam, passing underneath the chip concentrated power sources in a very effective way.

Title: Recent Achievements of the ATLAS Upgrade Planar Pixel Sensors
R&D Project
Abstract content
In the framework of the HL-LHC upgrade, the ATLAS experiment plans to introduce an all-silicon inner tracker with the HL-LHC upgrade to cope with the elevated occupancy.
To investigate the suitability of pixel sensors using the proven planar technology for the upgraded tracker, the ATLAS Planar Pixel Sensor R&D Project was established comprising 19 institutes and more than 90 scientists. Main areas of research are
- performance assessment and improvement of planar pixel sensors at HL-LHC fluences
- the achievement of slim or active edges to provide low geometric inefficiencies without the need for shingling of modules
- establishment of reliable device simulations for severely radiation-damaged pixel detectors
- the exploration of possibilities for cost reduction to enable the instrumentation of large areas with pixel detectors
The presentation will give an overview of the R&D project and highlight some accomplishments, among them
- beam test results with planar sensors up to innermost layer fluences
- measurements obtained with irradiated thin edgeless n-in-p pixel assemblies
- recent studies of the SCP technique to obtain almost active edges by post-processing already existing sensors based on scribing, cleaving and edge passivation
- update on prototyping efforts for large areas: sensor design improvements, 6” wafer production experience, 8” wafer production possibilities, concepts for low-cost hybridisation
Together, these results will allow an assessment of the state-of-the-art with respect to radiation-hard position-sensitive tracking detectors suited for the instrumentation of large areas.
Summary
To extend the physics reach of the LHC, upgrades to the accelerator are planned to increase the peak luminosity by a factor 5 to 10 which will enable the experiments to collect up to 3000 fb-1 of data. This, however, will lead to increased occupancy and radiation damage of the inner trackers, approaching fluences of a few 10^16 neq/cm2 at the innermost layer and still some 10^15 neq/cm2 at the outer pixel layers.
The ATLAS experiment plans to introduce an all-silicon inner tracker with the HL-LHC upgrade to cope with the elevated occupancy. With silicon, the occupancy can be adjusted by using the unit size (pixel, strip or short strip sensors) appropriate for the radiation environment. For radiation damage reasons, only electron-collecting sensors designs are considered (n-in-p and n-in-n): Beyond a fluence of about 10^15 neq/cm2, trapping becomes the dominant radiation effect and electrons are trapped significantly less than holes.
To investigate the suitability of pixel sensors using the proven planar technology for the upgraded tracker, the ATLAS Planar Pixel Sensor R&D Project was established comprising 19 institutes and more than 90 scientists. Main areas of research are
- performance assessment and improvement of planar pixel sensors at HL-LHC fluences
- the achievement of slim or active edges to provide low geometric inefficiencies without the need for shingling of modules
- establishment of reliable device simulations for severely radiation-damaged pixel detectors
- the exploration of possibilities for cost reduction to enable the instrumentation of large areas with pixel detectors
It has been demonstrated with sensors from different vendors that planar pixel sensors can be operated and still yield more than 5000 electrons of signal charge even above 1016 neq/cm2; hit efficiencies of well above 97% were obtained.
Special slim-edge designs have been implemented and tested and show a reduction of the inactive edges from 1100 µm in the current ATLAS Pixel Detector to only about ~200 µm. Further improvements towards fully active edges by SCP (scribe-cleave-passivate) and DRIE etching techniques have been prototyped and look promising.
The presentation will give an overview of the R&D project and highlight some accomplishments, among them
- beam test results with planar sensors up to innermost layer fluences
- measurements obtained with irradiated thin edgeless n-in-p pixel assemblies
- recent studies of the SCP technique to obtain almost active edges by post-processing already existing sensors based on scribing, cleaving and edge passivation
- update on prototyping efforts for large areas: sensor design improvements, 6” wafer production experience, 8” wafer production possibilities, concepts for low-cost hybridisation
Together, these results will allow an assessment of the state-of-the-art with respect to radiation-hard position-sensitive tracking detectors suited for the instrumentation of large areas.

Title: A scalable gigabit data acquisition system for calorimeters for
linear collider
Abstract content
This article presents the scalable Data Acquisition (DAQ) system that has been designed for prototypes of ultra-granular calorimeters for the International Linear Collider (ILC). Our design is generic enough to cope with other applications with some minor adaptations. The DAQ is made up of four different modules, including an optional one. One Detector InterFace (DIF) is placed at each end of the detector elements (SLAB) to communicate with up to 160 ASICs. A single HDMI cable is used to transmit both slow-control and readout data over a serial 8b/10b encoded characters at 50 Mb/s to the Gigabit Concentrator Card (GDCC). The GDCC controls up to 7 DIFs, it is distributing the system clock and ASICs configuration, and collecting data from them. Each DIFs data packet is encapsulated in Ethernet format and sent out via an optical or copper link. The Data Concentrator Card (DCC) is a multiplexer (1 to 8) that can be optionally inserted between the GDCC and the DIFs, increasing the number of managed ASICs by the GDCC. Using a single GDCC and 7 DCCs would allow a single PC to control and readout up to 8960 ASICs
(~ 500000 channels). The fourth card is the Clock and Control Card (CCC) that provides a clock and control fanout to up to 8 GDCCs and therefore to the entire system. A software suite (named Calicoes) written in C and Python manages the overall system. This system have been used for several tests on the SiW-ECAL prototype detector
(1800 channels). The full design and test results will here detailed.

Title: High-precision fiber-optical timing distribution systems over
large distances and their application to astroparticle physics
facilities
Abstract content
Future astroparticle physics facilities like CTA [1] and KM3NeT [2] require a relative timing precision better than 1 ns between detector elements separated by up to 100 km. At the same time, fiber-optical links for high-capacity data transfer from detector elements to central processing facilities are needed. The Open Hardware project White Rabbit [3] provides both data and time transfer functionality over the same optical fiber, and its implementation is currently being investigated for both facilities. Here, we present the current implementation status and performance measurements. In addition, propagation delays of optical 10 Gb/s data over a 75 km long amplified fiber link have recently been determined with an uncertainty of 4 ps [4]. This opens up the possibility of even more precise, picosecond-level precision time transfer over long-distance optical communication links for wide-area astroparticle detector arrays.

Title: Neutron-insensitive gamma-ray detector with aerogel for rare
neutral-kaon decay experiment
Abstract content
A novel gamma-ray detector which is highly sensitive to photons but insensitive to neutrons has been developed for the rare neutral-kaon decay experiment (KOTO experiment) at J-PARC.
This experiment aims to study the KL->pi0nunubar decay with an electromagnetic calorimeter and hermetic veto detectors surrounding the the decay region.
The veto counters located in the beam should be able to detect such photons as to be escaping to the direction with high efficiencies under the huge neutron flux of 500MHz.
This detector consists of a series of modules of lead and aerogel pairs.
Incident photons are converted to electrons and positrons in lead sheets and the photons from their Cerenkov radiation in the aerogel sheets are viewed by photomultiplier tubes.
Since protons or charged pions, which are mainly produced by neutrons, do not emit the Cerenkov light because of their small velocity, excellent blindness to neutrons can be achieved while keeping high photon detection efficiency around 99.9% for the energies larger than 1 GeV.
The half of the modules of the detector were installed and used as an in-beam photon veto detector in the first physics data taking of the KOTO experiment.
The detector operated stably during 1 week of data taking and the expected performance on photon detection was confirmed as a result of evaluation using KL->3pi0 decay events.
In this presentation, the design of this detector, stability and performance studies in the physics data taking, and the future prospects will be reported.

Title: Performance of the EUSO-BALLOON Front-End Electronics
Abstract content
Here the performance of EUSO-BALLOON front-end electronics with dedicated detector elements will be reported.
EUSO-BALLOON is a balloon-borne pathfinder of the space-borne fluorescence detector JEM-EUSO (Extreme Universe Space Observatory on board Japanese Experimental Module) on board the International Space Station.
The goal of EUSO-BALOON is to perform as a technological demonstrator of JEM-EUSO, to study the background and the detection of an atmospheric shower in a series of launches starting in 2014.
The EUSO-BALLOON focal surface consists of one Photo Detector Module (PDM) while the focal surface of JEM-EUSO will consist of 137 PDMs which corresponding to roughly 5,000 64-channel Multi-Anode Photomultiplier Tubes (MAPMTs). One PDM consists of 9 Elementary Cell units (EC_units). Each EC_unit contains 4 MAPMTs and a set of PCBs used to supply high voltages to the MAPMTs and to read out the output signals. These signals are transmitted to the front-end electronics, the EC-ASIC boards each of which contains 6 SPACIROC ASICs which has been developed for JEM-EUSO. To be operated in a space environment with a limited power budget, and covering a wide dynamic range for extreme energy cosmic ray (>5x10^19 eV) observation, the ASIC is designed to perform single photon counting in a dynamic range of 1 photoelectron (PE) to 300 PEs/pixel/2.5 µs, with double pulse resolution of 30 ns, and low power consumption (<1 mW/ch).
During the year 2013, the flight model EC_units and EC_ASIC PCBs were produced and the performance was successfully tested and confirmed.

Title: Scanning facility to irradiate mechanical structures for the
LHC upgrade programme
Abstract content
The existing luminosity of the LHC will be increased in stages to a factor of 10 above its current level (HL-LHC) by 2022. This planned increase in luminosity results in significantly higher levels of radiation inside the planned ATLAS Upgrade detector. This means existing detector technologies together with new components and materials need to be re-examined to evaluate their performance and durability within this enhanced radiation field. Of particular interest is the effect of radiation on the upgraded ATLAS tracker. To study these effects a new ATLAS irradiation scanning facility uses the Medical Physics Cyclotron at the University of Birmingham. The intense cyclotron beams allow irradiated samples to receive in minutes fluences corresponding to years of operation at the HL-LHC.
Since commissioning in early 2013 this facility has been used to irradiate silicon sensors, optical components and carbon fibre sandwiches for the ATLAS upgrade programme. Irradiations of silicon sensors and passive materials can be carried out in a temperature controlled cold box which moves continuously through the homogenous beamspot. This movement is provided by a pre-configured XY-axis cartesian robot system (scanning system). This paper reviews the design, development, commissioning, performance results and future plans of the irradiation facility, fully operational since 2013.
Summary
In 2022 the luminosity of the LHC will be increased in stages to a factor of 10 above its current level. This planned increase in luminosity results in significantly higher levels of radiation inside the planned ATLAS Upgrade detector with detrimental effects to existing detector technologies. To study these effects a new bespoke ATLAS high intensity proton irradiation scanning facility has been constructed using a Cyclotron at the University of Birmingham, enabling the evaluation of future detector technologies in several minutes as opposed to years of operation. This paper reviews the design, development, commissioning, performance results and future plans of the irradiation facility, fully operational since 2013.

Title: Luminescent and scintillation properties of LFS-3 and GAGG:Ce
crystals
Abstract content
Many of the contemporary photonics technologies dealing with detection of radiation owe their existence to diverse scintillation materials. The scintillators play a decisive role in the registration of X-rays and γ-quanta necessary in many fields of application in industry, medicine, fundamental research, and security where they are used to convert high-energy photons into visible light. Co-doped LFS-3 and mixed GAGG:Ce recently developed from Zecotek Photonics Inc. and Furukawa Co Ltd companies respectively. These crystals are very fast, with high density and very high light output. Their absorption, excitation and emission spectra were measured and compared. Results indicate that the difference between the emission intensities among GAGG:Ce samples seems to be more pronounced than in the case of LFS-3 crystal samples. However, the relative average deviation of the emission intensities does not exceed the experimental error. Moreover, pulse amplitude spectra were performed using for excitation a 137Cs gamma-radiation source. A standard Ø40x40 mm NaI(Tl) detector was used for reference and values of energy resolution and light output (% to NaI(Tl)) were determined. Energy resolution was measured by reading out the light emerging from one end (3x3 face) of the crystals, using a Hamamatsu R1307 PMT connected to an appropriate amplifier and a Multy Channel Analyzer (MCA). Best energy resolution values of 7.3% for a 3x3x20mm^3 GAGG:Ce crystal sample and 8,9% for a 3x3x10mm^3 LFS-3 sample were recorded.

Title: Development of Superconducting Tunnel Junction Photon Detector
on SOI Preamplifier Board to Search for Radiative decays of Cosmic
Background Neutrino.
Abstract content
We develop superconducting tunnnel junction (STJ) to search for radiative decays of cosmic background neutrino using cosmic infrared background energy spectrum.
The requirement for performance of the detector in our experiment is to detect a single far-infrared photon.
We can detect a single far-infrared photon with Nb/Al-STJ theoretically. So far we have not succeeded in detecting it yet because the signal of a single far-infrared photon with the STJ is too small comaparing with the present noise of our electronics.
To solve this problem, we use a charge sensitive preamplifier that can operate at low temperature around 1K to improve the signal-to-noise ratio of STJ.
cSOI(Silicon on Insulator) preamplifier is a candidate of the preamplifier as it was proved to operate at 4K by a JAXA/KEK group.
We have developed a STJ processed on a SOI preamplifier board to make this detector compact.
Firstly, we have processed STJ on a SOI board with only SOI-MOSFET's to check the connection between STJ and SOIFET and the STJ processing without any damage on SOIFET.
We confirmed that the SOIFET had excellent performance below 1K and the STJ on SOI could operate normally.
Then we made and tested the second version of SOI-STJ detector with the readout circuit on SOI wafer as the charge sensitive amplifier.
We will report the present status of development of this SOI-STJ detector.

Title: PETIROC2 : 32 ch SiGe SiPM readout ASIC for GHz time and
charge measurement
Abstract content
PETIROC2 is a 32 channel readout ASIC for high speed readout of SiPM matrixes. It features a 1 GHz 20 dB preamp followed by 1 GHz high speed discriminator and time-to-amplitude converter to measure the time down to 50 ps. A variable shaper channel measures the charge over 10 bits and also feeds a discriminator for high level signal trigger. The time and charge signals are digitized internally so that the chips can output only digital signals.
The ASIC is realize in SiGe 0.35um technology and takes largely advantage of the SiGe bipolar transistors to achieve GHz bandwidhts at a few mW power/channel. The chip was submitted in november 13 and is presently at dicing, experimental results will be available at the conference.

Titre: Study of a Large Prototype TPC using Micro-Pattern Gas
Detectors
Abstract content
In the last decade, R&D of detectors for the future International Linear Collider (ILC) has been carried out by the community. The International Large Detector (ILD) is one detector concept at the ILC where calorimetry and tracking systems are combined. The tracking system consists of a Si vertex detector and forward tracking disks coupled to a large volume Time
Projection Chamber (TPC).
Within the framework of the LC-TPC collaboration, a Large Prototype (LP) TPC has been built as a demonstrator. Its endplate is able to contain up to seven identical Micro-Pattern Gas Dectectors (MPGD) modules. Recently, the LP has been equipped with resistive anode Micromegas (MM) or Gas electron Multiplier (GEM) modules. Both the MM and GEM technologies have been studied with a 5 GeV electron beam in a 1 Tesla magnet.
After introducing the LP, the current status, recent results (drift velocity, field distortions, ion gate and spatial resolution measurements) as well as future plans of the LC-TPC R&D with MM and GEM will be presented.
