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.

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.

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.

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.

Besides established detection techniques using a 3000 km2 array of particle detectors sampling shower particles at ground level, and detecting fluorescence light emitted during the shower development with telescopes, the Observatory explores the potential of radio detection of cosmic rays with the Auger Engineering Radio Array (AERA). Radio detection has the potential to provide information on e.g. cosmic ray shower properties with a duty-cycle not limited by day and moon light as in case of the fluorescence technique. AERA consists of 124 autonomous detector stations sensitive to MHz frequencies. The stations feature dual-polarized radio antennas, custom low-noise analog and digital electronics and a broad-band wireless communication system. With AERA we face the challenge of self-triggering on the radio pulse in a background dominated environment by implementing various real-time signal processing strategies within the station electronics. Complementary, we explore the potential of the radio technique as an integral part of future multi-component detectors by utilizing trigger information from the other Auger detectors and recently, by particle detectors integrated in the radio stations. We will discuss the current cosmic ray measurements and the status and prospects of AERA.

Many technological improvements are foreseen during the planned upgrade; among what most concerns the core of the GERDA experiment there will be: i) the complete rearrangement of the Germanium naked detector array configuration and its handling in the cryogenic (liquid Argon), hostile environment; ii) the major redesign of the cryogenic front-end preamplifiers (CC3), that will be specifically suited to the new low capacitance Broad Energy (BE) Ge detectors and iii) the optimization of the off-line subsequent digital processing, for better energy estimation and pulse shape discrimination of the HPGe waveforms. Given the even tighter specifications of the GERDA phase II experiment with respect to phase I (e.g. energy resolution, pulse shape discrimination, etc.) and the even more stringent associated constraints (e.g. lower-background materials, more deployed detectors, flexibility in handing detectors and associated electronics, etc.), the whole design process turns out to be multi-objective, iterative and multi-disciplinary (involving e.g. physics, electronics, mechanics, leading-edge technologies such as nano-structured materials, etc.). The main steps of this roadmap, a few non-trivial key points (e.g. concerning the design of the very front end electronics) and the overall final results in terms of positive achievements and associated drawbacks will be presented, together with the expected preliminary results of the commissioning phase.

For stable operations, both need to be kept constant. In an ILC calorimeter with millions of channels this is a challenging task. It is, therefore, desirable to compensate automatically for temperature variations by readjusting the bias voltage. We have designed an adaptive power supply to achieve this task. We anticipate a gain stability at the level of 1%. First, we present measurements of the gain dependence on temperature and bias voltage for several SiPMs from three different manufacturers and determine the dV/dT dependence. We then demonstrate the performance of the gain stability with a prototype that was constructed in industry after performing measurements with a test board.

Its goal is the detection of Extreme Air Showers (EAS) above a few 10^19 eV, developing underneath at a distance of about 400 km, in the troposphere. The SPACIROC family is dedicated to readout 64-channel Multi Anode PMT (MAPMT) or similar detectors. The two main features of this ASIC are the photon counting for each input and the charge-to-time (Q-to-T) conversions for each 8-channel sum. In the photon counting mode, the 100% trigger efficiency is achieved for 1/3 photo-electron (pe) input charges and in order to avoid pile-up in case of a large flux of photons, the double pulse resolution is required to be shorter than 10ns. For the Q-to-T converter, the ASIC should operate in a large dynamic range (1pe to 100pe per pixel). The operating conditions of JEM-EUSO require having low power dissipation (1mW/channel). High-speed performances with low power are obtained thanks to the SiGe technology used for the ASIC. This ASIC has been submitted in three successive versions: SPACIROC1, which showed global good behavior, has been used to equip the EUSO-BALLON instrument. The second version was a conservative design to improve performances and decrease power consumption. The third version has been designed to improve the double pulse separation and to increase the charge dynamic range thanks to new front end architecture. The design and performances (with and without MAPMT) of the third version of SPACIROC are presented in TIPP2014 paper.

The GEM detector will replace the current inner drift chamber that is suffering early aging due to the increase of the machine luminosity. The new inner tracker is expected to match the momentum resolution (σpt/Pt~0.5% at 1 GeV) and radial resolution (σxy~100μm) of the drift chamber and to improve significantly the spatial resolution along the beam direction (σz ~150μm) with very small material budget (about 1X0). The inner tracker will be composed by three layers of triple cylindrical GEM with an angular coverage of 93% of the solid angle. Each layer is composed by five cylindrical structures: the cathode, three GEMs and the anode readout. To minimize the material, no support frames are used inside the active area and the GEM foils are mechanically stretched being glued to fiberglass rings at their ends. The anode configuration is studied by means of Maxwell and Garfield simulations and with a small-scale planar prototype that is tested with cosmic rays. Preliminary R&D and simulation studies will be presented together with the mechanical design of the detector. Due to the 1 T magnetic field of the experiment an analog readout is mandatory to achieve the desired spatial resolution; the charge will be measured with “time-over-threshold” technique. Our plan to develop a new ASIC chip based on UMC-110nm technology with limited power consumption will be also presented.
