It determines polarisation by measuring the azimuthal angular distribution of Compton scattered photons in a plastic scintillator array. The use of an all plastic target yields a relatively large but low mass detection area. The dominant source of background for the polarisation measurements has been shown through Geant4 simulations to originate from high energy (MeV range) atmospheric neutrons. Neutrons can pass the instrument's Bismuth Germanium Oxide (BGO) anticoincidence shield undetected and subsequently scatter between plastic scintillator elements to produce a polarisation signature. A passive 15 cm thick polyethylene shield surrounding the polarimeter reduces the neutron induced background by an order of magnitude. The background level remains however significant, prompting the need for active monitoring of the continuously changing neutron flux. For this purpose PoGOLite makes use of a neutron sensitive phoswich scintillator cell. The phoswich cell consists of a 5 mm thick Lithium Calcium Aluminium Fluoride (LiCAF) scintillator, used for neutron detection. The LiCAF is surrounded by a BGO anticoincidence system. This small light weight detector can therefore be used to measure the neutron flux even in high radiation environments. This type of neutron detector was tested on a separate dedicated stratospheric balloon mission, called PoGOLino, prior to the PoGOLite flight which took place in July 2013. Results from both flights will be presented and implications on the polarisation measurements of PoGOLite from 2013 will be discussed.

This, in conjunction with the compactness of the inner volumes, poses several challenges for the design of a cooling system that is able to fulfil the required detector specifications. This presentation introduces a detector cooling strategy using dry air as a coolant and shows the results of computational fluid dynamics simulations and experimental measurements used to validate the proposed strategy. Furthermore, the progress on the development of lightweight detector support structures that fulfil both mass and stiffness requirements is also reported.

To improve the sensitivity by one order of magnitude, a major upgrade of the detector is planed. The energy and position resolutions of the liquid xenon (LXe) gamma ray detector are limited near the entrance-window by the limited size of the photomultiplier tubes (PMTs). For the upgrade, 2-inch PMTs on the entrance-window are supposed to be replaced by $12\times12$ cm${}^2$ silicon photomultipliers (SiPMs). According to a simulation study, the higher granularity will improve the energy resolution from 2.4\% to 1.1\% and the position resolution from 5 mm to 2 mm around the entrance-window. To be used in LXe, SiPMs are required to be able to detect vacuum ultra-violet photons (175 nm), be operational in the LXe temperature (165 K) with high enough photo-detection efficiency (PDE) and the gain uniformity. A new type of SiPM is being developed and were tested in LXe. The single-photoelectron detection capability was confirmed, and the PDE for the LXe scintillation light was measured to be 17\%. To address an issue of long tail of the pulse due to the large capacitance, a new connection scheme (connecting signal and bias lines in series and in parallel, respectively) was proved to make the pulse shorter. A large prototype of the LXe detector with using $\sim$600 SiPMs will be built in 2014 followed by the construction of the full size detector, where $\sim$4000 SiPMs will be used.

Such sensors have properties such as high-speed operation, low-power dissipation, and SEU/SET immunity. The major issue in applications them in high-radiation environments is the total ionization damage (TID) effects. The effects are rather substantial in the SOI devices since the transistors are enclosed in the oxide layers where generated holes are trapped and affect the operation of the near-by transistors. The double SOI sensors that provide an independent electrode underneath the buried oxide (BOX) layer have been developed. A negative voltage applied to this electrode is expected to cancel positive potential due to hole traps in the BOX layer. We have irradiated transistor test elements and pixel sensors with γ-rays. By adjusting the potential of this electrode, the TID effects are shown to be compensated. The transistors irradiated to 2 MGy recovered their performances by applying a bias to the electrode. Transistors were shown to have modest differences in behaviors of TID compensations according to their types. Furthermore, differences depending on the biasing condition during irradiation were observed. The pixel sensor irradiated to 100 kGy recovered its functionality by applying a bias to the electrode. We used infrared laser pulse and γ-ray sources to evaluate TID compensations of pixel sensors. The radiation tolerance of the SOI devices has been substantially improved by employing the innovative double SOI.

These cost-effective GRPC stand high particle rate. The excellent timing they can provide could allow to improve on the trigger rate and reduce the pileup consequences of the LHC luminosity increase. Single and multi-gap GRPC using low-resistivity glass are being proposed to equip high eta region of experiments such CMS. Electronics readout with a time measurment precison of less than 25 ps is being developped to equip such detectors. Summary With the increase of the LHC luminosity foreseen in the coming years many detectors currently used in the different LHC experiments will be dramatically impacted and some need to be replaced. The new ones should be capable not only to support the high particle rate but also to provide excellent timing to reduce the data ambiguity due to the expected high pileup. RPC using low-resistivity glass are proposed to equip the very forward region of the LHC experiments. In their single-gap version they can stand rates of few kHz/cm2. Their time precision of about 1ns could in principle allow to reduce the noise contribution, leading to an improvement of the trigger rate. In their multi-gap version they can do better in both the particle rate detection and the time precision measurement. Time precision of less 25 ps could be obtained. This aims at reducing the ambiguity the high expected pileup will introduce. In both cases new electronics equipped with excellent timing precision measurement are being developed to read out the RPC detectors. Tests are ongoing to validate the different scenarios.

[Tipp2014] Questions re: TIPP2014 Abstract Submission
by Hassan Chagani 27 Jan '14

27 Jan '14

Dear Sir/Madam, I would like to submit an abstract for TIPP 2014, but had a few questions regarding the abstract submission form. I did try to search for the answers before writing this email, but to no avail. Hopefully, answering my questions will not take up too much of your time. 1. There is a field titled 'Summary'. Although it is not a mandatory field, I am not sure of what should be written there as the abstract seems to fit better in the 'Abstract content' field. What is the purpose behind the 'Summary' field? 2. It is not possible to specify the 'Presentation type'. Is this deliberate? Will there be any poster sessions, or will the conference only consist of talks? 3. What is the difference between a 'Primary Author' and 'Co-Author'? I assume that the former can change the abstract, but the latter cannot. Is this correct, and is this the only difference? Sorry if all of these questions have already been answered on your website and I simply haven't been able to find the answers. Thank you in advance for your help. Yours Faithfully, Hassan Chagani.

The data were analysed using an electrical model of the SiPM which allowed determining characteristic parameters like pixel capacitance, quench resistor and quench capacitance, parasitic resistance, and breakdown voltage in different ways, and studying their dependence on X-ray dose. In addition, the doping profile and the electric field distribution in the SiPM have been determined. It is found that the electrical model provides a consistent description of the data. The main changes with X-ray dose are a decrease of the parasitic resistance, and an increase in dark current due to current generation at the Si-SiO2 interface. Whereas for dose values of 20 kGy and below the surface generation current hardly affects the properties of the SiPM above the breakdown voltage, it gets amplified for dose values above 20 kGy resulting in a significant increase in dark-count rate. Apart from this effect, the performance of the Hamamatsu SiPM as high-gain photo detector is hardly affected by X-ray radiation up to a of 20 MGy. Summary Hamamatsu Silicon Photo Multipliers (SiPM) of the type S10362-11-050P are characterized and the change of their parameters after irradiation to X-rays of 200 Gy, 20 kGy, 2 MGy and 20 MGy determined.

Meanwhile, full CMOS integration in the pixel is achievable due to the availability of deep P-well. Therefore, a novel concept of pixel with integrated discriminator was realized to develop a fast and power efficient rolling shutter CPS architecture for the ALICE-ITS upgrade. Compared with the conventional CPS using column-level discrimination, the in-pixel discrimination sets the analog processing within the pixel. Thus the analog buffer driving the long distance column bus is no longer needed and the static current consumption per pixel can be largely reduced from 120µA down to 15µA. Besides, the row processing time can be halved down to 100ns thanks to small local parasitic. As a proof of concept, the prototype chip called AROM0 was fabricated in April 2013. Full functionality and the noise performance of the chip have been validated in laboratory test. Based on the experience of AROM0, the improved pixel designs have been implemented in the chip called AROM1 which is an intermediate prototype chip anticipating the final sensor architecture proposed for the ALICE-ITS upgrade. It features the pixel array of 64 × 64 with double-row readout while integrating the on-chip biasing/reference control and JTAG programmable sequence management circuitry. This paper will present the design and test results of AROM0. It’ll also discuss the improvement in AROM1 and present the test results of this sensor which is expected in early 2014.

This detector is being developed by the network NEWs, which includes several applications. We can name between many others Dark Matter searches, low level radon and neutron counting or low energy neutrino detection from supernovas or nuclear reactors via neutrino-nucleus elastic scattering. In this context, this works will present the characterization of a spherical detector of 1 meter diameter using two argon-based mixtures (with methane and isobutane) and for gas pressures between 50 and 1500 mbar. In each case, the energy resolution shows its best value in a wide range of gains, limited by the ballistic effect at low gains and by feedback at high gains. Moreover, the best energy resolution shows a degradation with pressure. These two effects will be discussed in terms of gas avalanche properties. Finally, the effect of an electrical field corrector in the homogeneity of the gain and the energy threshold measured in our setup will be also discussed.

The Mini-balloon filled with 136Xe loaded liquid scintillator was installed in the KamLAND detector. From the first result of KamLAND-Zen, there was the BG peak at 2.6 MeV region. As a result of data analysis, it was found that 110mAg was the BG candidate. The purification system of xenon and liquid scintillator were developed to remove the 110mAg BG. 136Xe gas was collected from the liquid scintillator in the Mini-balloon to purify 136Xe gas and liquid scintillator, respectively. In addition, 136Xe gas was purified using SASE getter just before dissolving 136Xe into liquid scintillator. The 2nd phase of KamLAND-Zen was started in 2013. I will report the status of KamLAND-Zen and purification methods.

For this purpose we design and test a massively parallel pattern-recognition algorithm, inspired by studies of the processing of visual images by the brain as it happens in nature. We find that high-quality tracking in large detectors is possible with sub-microsecond latencies if the algorithm is implemented in modern, high-speed, high-bandwidth FPGA devices.

To get the stable working time, lower discharge rate with long working term and higher effective gain, the new structure detector has been designed. One structure was based the coated Ge resistive anode readout with bulk Micromegas detector, and the other structure was combined with the detection’s advantages of Micromegas and gas electron multiplier (GEM), which was composed of a Micromagas chamber with one GEM foil as preamplifier. In this paper, the two structures of the detectors and detection principles were presented in details. Using a 55Fe X-ray radioactive source in the operation mixtures gas of argon and isobutene (Ar/Iso=95/5), the performances of the detector gain, discharge rate, energy resolution and stable working time are investigated. A further measurement in the four operation mixtures gas has been accomplished at 1W1B laboratory of Beijing Synchrotron Radiation Source. In the experiment, the energy range of X-ray was set from 6 keV to 20 keV and the setting step was 1 keV. Finally, the data of beam test were obtained and analyzed. The preliminary results show that a stable working time could reach more than 30 hours of continuous work, the gain of the detector could exceed 10^6 and the discharge rate could be reduced by nearly 100 times at the same gain.

Materials of different densities can be differentiated using this technique as muons interacting with high-Z materials are scattered to a greater degree by multiple Coulomb scattering than low-Z materials. This scattering is determined experimentally by detecting the incoming and outgoing trajectory of the muon as it enters and exits the inspection volume. This technique is particularly useful for visualising volumes that are difficult to inspect visually. AWE is primarily interested in investigating the use of MST for scanning cargo containers, as it could be used for the detection the presence of radiological material without introducing an artificial radiation source. AWE is currently testing and developing two MST experimental systems based on drift chamber technology. One of the experiments is constructed using six layers of three adjacent drift chambers positioned above and below an inspection volume. The second system is a similar configuration and is constructed of drift tubes. The technical challenges of producing the experimental system with a resolution capable of accurately determining the muon scattering angle within a few milliradians will be detailed and the experimental results obtained compared with Monte Carlo models.

Wireless technology has features attractive for data transfer in future tracking detectors. The removal of wires and connectors for data links is certainly beneficial both for the material budget and the reliability of the system. Other advantages is the freedom of routing signals which today is particularly complicated when bringing the data the first 50 cm outside the tracker. With wireless links intelligence can be built into a tracker by introducing communication between tracking layers within a Region Of Interest which would allow the construction of track primitives in real time. The wireless signal is transmitted by a passive antenna structure which is clearly a much less complex and radiation hard object than an optical transmitter. The technology used in consumer goods are however not suitable for trackers. The first limitation is the low data transfer capacity with current 5 GHz transceivers but also the relatively large feature sizes of the components. Due to the requirement of high data rates in detectors a high bandwidth is required. The frequency band around 60 GHz turns out to be a very promising candidate. The frequency is a strong candidate for future WLAN use hence components are available on the market. The high baseband frequency allow for data transfer of the order of several Gbit , and due to the small wave length in the mm range, only small structures are needed. The challenge is to bring the signal around or trough boundaries that are not transparent to the mm-waves like silicon detector modules or support structure. Further more low power operation and strong focusing antennas is required for massive parallelization of data transfer inside the tracker. We will present patch antennas produced on flexible Printed Circuit Board substrate that can be used in future trackers. The antennas can be connected to transceivers for data transmission/reception or be connected by wave-guides to structures capable of bringing the signal pass boundaries. This presentation aims to present results on simulation, modelling, fabrication and characterisation of such antennas. Studies of a 60 GHz data link for radial transmission of mm-waves through a ATLAS detector model will be shown.

It comprises a calorimeter system composed of four subdetectors: an electromagnetic calorimeter (ECAL) followed by a hadron calorimeter (HCAL). In addition the system includes in front of them the Scintillating Pad Detector (SPD) and Pre-Shower (PS). They are used to select transverse energy hadron, electron and photon candidates for the first trigger level and they provides the identification of electrons, photons and hadrons as well as the measurement of their energies and positions. The calorimeter has been pre-calibrated before its installation in the pit, and the calibration techniques have been tested with the data taken in 2010. During operation, hadronic, leptonic and photon triggers of particular interest for hadronic B decays and radiative decays are provided by the calorimeter system. The design and construction characteristics of the LHCb calorimeter will be recalled. Strategies for monitoring and calibration during data taking will be detailed in all aspects.

Summary The LHCb experiment is dedicated to precision measurements of CP violation and rare decays of B hadrons at the Large Hadron Collider (LHC) at CERN (Geneva) [1, 2]. LHCb is a single-arm spectrometer with a forward angular coverage from approximately 10 mrad to 300 mrad. It comprises a calorimeter system composed of four subdetectors [3], selecting transverse energy hadron, electron and photon candidates for the first trigger level (L0), which makes a decision 4µs after the interaction. It provides the identification of electrons, photons and hadrons as well as the measurement of their energies and positions. The set of constraints resulting from these functionalities defines the general structure and the main characteristics of the calorimeter system and its associated electronics. A classical structure of an electromagnetic calorimeter (ECAL) followed by a hadron calorimeter (HCAL) has been adopted. In addition the system includes in front of them the Scintillating Pad Detector (SPD) and Pre-Shower (PS), which are two planes of scintillating pads separated by a 2.5 radiation length lead sheet, aimed at tagging the electric charge and the electromagnetic nature of the calorimeter clusters for the first level of trigger. ECAL, PS and SPD account for about 6000 channels each with three degrees of granularity, concentric around the beam pipe, namely, the inner, the middle and the outer parts. HCAL is made of about 1500 channels and is divided into two parts only. All four detectors are arranged in pseudo-projective geometry and follow the general principle of reading the light from scintillator tiles with wave-length shifting fibers, and transporting the light towards photomultipliers, all following the 25 ns readout. During operation, hadronic, leptonic and photon triggers of particular interest for hadronic B decays and radiative decays were provided by the calorimeter system. The calorimeter has been pre-calibrated before its installation in the pit, and each part of the calorimeter system follows a different strategy for calibration. The calibration techniques have been tested with the data taken in 2010 and have evolved to improve performances taking benefit of the high statistics recorded. Detector ageing are scrutinized regularly. They affect detector response and trigger rates but the severity of the impact on data depends on the detector type and of its use. Calibration techniques are also used to compensate for these effects. For instance ECAL aging effects can be seen from the variation on the 0 mass peak fit and the 0 peak resolution fits for calibration over time (figure 1). Regularly, a precise calibration is derived from a large sample of 0 from two separated photons. Short term effects are followed with electrons from conversion looking at the ratio of the deposited energy of the electron in the calorimeter to its momentum measured by the tracking system (E/p) in ranges of ~40 pb-1. Initial performances of the electromagnetic calorimeter and its expected resolution are recovered for 0 and B decays including photons. The design and construction characteristics of the LHCb calorimeter will be recalled. Strategies for monitoring and calibration during data taking will be detailed in all aspects. Scintillating fibres, plastics and photomultipliers suffer from ageing due to radiation damage or high currents. Different methods which are used to calibrate the detectors and to recover the initial performances will be presented. The performances achieved will be illustrated in selected channels of interest for B physics.

See below a detailed summary of your submitted abstract: Conference: Tipp 2014 - Third International Conference on Technology and Instrumentation in Particle Physics Submitted by: SFORZA, Federico Submitted on: 24 January 2014 11:28 Title: Upgrade of the ATLAS muon spectrometer with the installation of new precision drift-tube chambers in 2014 Abstract content We present the 2014 upgrade of a section of the muon tracker with drift-tube chambers characterized by a new technology, with smaller tube diameter than the present Monitored Drift-Tube (MDT) chambers. Each new chamber is composed by eight layers of aluminum tubes with a diameter of 15 mm, against to the six layers of 30 mm aluminum tubes used in the corresponding ATLAS MDT chambers. The newly installed chambers allow a simple integration with the services systems, electronic and muon reconstruction software. Furthermore the compact geometry of the chambers allows the installation in problematic regions of the detector structure which are, at present, instrumented with only two MDT stations instead that three as in the optimal case. The new chambers will be installed in the elevator pit area used for access to the ATLAS detector. The instrumentation of this region is possible using a movable detector structure with alignment precise at the level of 30~$\mu m$ and integrated with the rest of the ATLAS muon spectrometer. The momentum resolution for 1~TeV muons will be improved by approximately $30$\% in the newly instrumented detector regions. Summary The 2013-2014 shutdown of the Large Hadron Collider (LHC) at CERN offers the opportunity to improve the performance of the ATLAS detector with the installation of new detector components. However the relatively short time window and the constraints due to the integration of the new components with the existing infrastructure limits the range of available solutions. We present the upgrade of a section of the ATLAS muon tracker with drift-tube chambers characterized by a new technology, with smaller tube diameter than the present Monitored Drift-Tube (MDT) chambers. The proposed layout balances between maximizing the coverage with muon stations, the tight constraints of the integration with the present infrastructure, and the benefits of using the new stations for detector R\&D. Each new chamber is composed by eight layers of 78 aluminum tubes with a diameter of 15 mm, against to the six layers of 30 mm aluminum tubes used in the corresponding ATLAS MDT chambers. A gold-plated tungsten-rhenium anode wire is tensed at the center of the tubes and its position is known to better than 10~$\mu$m. The design remains fully compatible with the present services, read-out and trigger scheme but the more compact geometry of the chambers allows their installation in problematic regions of the detector structure. The presence of additional tube layers allows for redundancy in the track reconstruction and better noise rejection in the dense tracking environments expected in the future LHC run conditions. Two new chambers will be installed in the ATLAS detector elevator shaft. This region, covering an area of $\Delta \eta \times\Delta\phi\approx 0.2\times 0.3$ and corresponding to 2\% of the ATLAS barrel region, is used to access the inner part of the ATLAS detector and the ease of accessibility must be maintained. This additional challenge has been solved by installing the stations on movable supports and using an optical alignment system, precise at the level of 30~$\mu m$, integrated with the rest of the ATLAS muon spectrometer. The upgrade will increase the area of the muon spectrometer instrumented with three layers of precision tracking chambers. This will improving the momentum resolution, for 1~TeV muons, by approximately $30$\%. The newly installed chambers will also allow for test of the small drift-tube technology during the LHC Run II data taking, starting in 2015, so to prepare for the additional upgrades that will use this technology, planned for the ATLAS phase II.

Before 2018 the instantaneous luminosity of the LHC is expected to reach 2x1034cm−2s−1, which will significantly increase the number of interactions per bunch crossing. The current pixel detector of CMS was not designed to work efficiently in such a high occupancy environment and will be degraded by substantial data-loss introduced by buffering in the analogue readout chip (ROC) and effects of radiation damage in the sensors, built up over the operational period. To maintain a high tracking efficiency, CMS has planned to replace the current pixel system during „Phase 1” (2016/17) by a new lightweight detector, equipped with an additional 4th layer in the barrel, and one additional forward/backward disk. A new digital ROC has been designed, with increased buffers to minimize data-loss, and a digital readout protocol to increase the readout speed. Prototypes of digital single-chip modules have been characterized in an electron test beam at DESY, before and after irradiation. Even after the expected 4th layer lifetime dose of 130kGy, the prototypes were measured to be ~99% efficient and the spacial resolution remained ~7μm. Furthermore, energy calibrations using monochromatic X-rays were performed, and its dependence on irradiation and temperature were studied. This talk will give an overview of the upgraded detector with an emphasis on the status of the module production and testing of the 4th layer, which is being assembled and pretested by German institutes. Summary This talk will give an overview of the CMX pixel "Phase 1" upgrade with an emphasis on the status of the module production and testing of the 4th layer.

The data are being analyzed within the CALICE collaboration. However preliminary results indicate that a highly granular hadronic calorimeter conceived for PFA application is also a powerful tool to separate pions from electrons. The SDHCAL provides also a very good resolution of hadronic showers energy measurement. The use of multi-threshold readout mode shows a clear improvement of the resolution at energies exceeding 30 GeV with respect to the binary readout mode. New ideas to improve on the energy resolution using the topology of hadronic showers will be presented.
