Bolometers are excellent detectors to search for this rare decay, thanks to their good energy resolution and to the low background conditions in which they can operate. The current challenge consists in the reduction of the background, represented by environmental $\gamma$s and $\alpha$s, in view of a zero background experiment. This can be obtained with the approach of the LUCIFER project, funded by an European grant, which is based the double read–out of the heat and scintillation light produced by ZnSe scintillating bolometers, that allows to discriminate between $\beta/\gamma$ and $\alpha$ particles. The LUCIFER experiment aims at a background lower than 10$^{3}$ counts/keV/kg/y in the energy region of the $0\nu$DBD of $^{82}$Se, an order of magnitude lower with respect to the present generation experiments. Such a low background level will provide a sensitivity on the effective neutrino mass of the order of 100 meV. We describe the current status of the LUCIFER project, including results of the recent R&D activity.

The second generation pCT system being developed at Northern Illinois University in collaboration with Fermilab and Delhi University is comprised of a tracking system, a calorimeter or the range detector, data acquisition system, a computing farm, and software algorithms for image reconstruction. The proton beam encounters the upstream tracking detectors, the patient or phantom, the downstream tracking detectors, and a calorimeter. The tracking detectors are scintillating fibers and the calorimeter is made up of stacked scintillator plates. The data acquisition sends the proton scattering information to an offline computing farm. The pCT detector design allows for an increased data acquisition rate (up to 5 million proton tracks per second) and an improved imaging algorithm, which significantly reduced reconstruction times of three dimensional images. In this presentation, we will present the current status of the pCT detector system, development of the complete detector simulation and reconstruction tools and their validation, and preliminary test beam data analysis with the full pCT detector system.

They advance new challenges on the diagnostic equipment. Several of the basic requirements for a modern diagnostic technique are an easy scaling on multi-channel measurement systems, simultaneity of recording channels and the possibility of adapting the equipment by different diagnostics. Based on these concepts, a data acquisition system for GOL-3 and GDT magnetic mirror traps (Budker Institute, Novosibirsk, Russia) is developed. It is comprised of the signal recorder operating in a real-time mode, based on the ADC with the sampling frequency of 500 MHz and the amplitude resolution of 12 bits, the synchronization system to provide in-phase operation of multiple channels of the recording system and the communication modules for interfacing with an operator’s PC via the Ethernet 10/100 channel. Thanks to building the digital circuitry of the recorder based on a PLD (Programmable Logic Device), the data acquisition system software includes the ability to modify data processing algorithms for the specific diagnostics (interferometry, laser scattering, spectroscopy, refractometry and others) in a real-time mode. The synchronization system consists of two main modules: the timer and the synchronization unit. The accuracy of binding of the output data bundle to the trigger pulse is determined by the sampling frequency of data acquisition system recorders.

A key advantage of using CO2 as refrigerant is the high heat transfer capability allowing a significant material budget saving, which is a critical element in state of the art detector technologies. At CERN new CO2 cooling system has been constructed to serve for new ATLAS Insertable B-Layer (IBL) detector. Two independent cooling units, sharing one common accumulator, placed about 100m from the heat source, are designed to cool 14 individual staves with evaporative CO2 at the given pressure. This paper describes the general system design, innovative redundancy approach, maintenance philosophy, control system implementation and the commissioning results including the performance tests in the proximity of the detector. Additionally the different failure scenarios and recovery techniques including cooling units swap procedure will be discussed. The system tests and challenging commissioning proved precise temperature control over the long distance and expected performance. Looking forward for the IBL detector installation, cooling system will be prepared to serve for the next Large Hadron Collider physics run.

Abstract content Daniela Calvo on behalf of the PANDA MVD group. The fixed target experiment PANDA is one essential part of the FAIR facility in Darmstadt and is going to study the interactions of antiproton beams, featuring unprecedented quality and intensity, on protons and on nuclei. It includes the Micro Vertex Detector (MVD) [1], as innermost detector of the tracking system, specially able to detect secondary vertices of short-live particles. Due to the forward boost the MVD layout is asymmetric with four barrels surrounding the interaction point and six disks in the forward direction. The innermost layers are composed of hybrid epitaxial silicon pixels and the outermost ones of double sided silicon strips, with about 10^7 pixels and 2x10^5 strips channels. PANDA features a triggerless architecture, therefore the MVD has to run with a continuous data transmission at a high interaction rate (about 10^7 int./s) where hits have precise timestamps (the experiment clock is 155.52 MHz). In addition the energy loss of the particles in the sensor should be measured. To cope with these requirements custom readout chips are under development for both pixel and strip devices. The powering and cooling of the readout are challenging since the MVD volume is limited by the surrounding detectors and the routing is only foreseen in the backward direction. Support structures are made of carbon fibers and high thermally conductive carbon foam with embedded cooling pipes beneath the readout chips is integrated. The presentation is focused on the technological aspects of the design and the integration of this detector in PANDA.

Due to the CCD's low electronic readout noise (R.M.S. ~ 3 eV), this instrument is able to reach a detection threshold of 60 eV, suitable for the search in the low mass range. The excellent energy response and high spatial resolution of a CCD image allow a powerful background characterization. Early DAMIC runs determined the world's best cross-section limits for WIMPs with masses below 4 GeV. Here we report on DAMIC100, a fully funded dark matter search detector with a target mass of 100 grams of silicon that will be installed at Snolab during the Summer of 2014. We also discuss the challenges associated with the scale-up of the experiment, the calibration efforts for low energy nuclear recoils in silicon, and the prospects for the first physics results after a one year run.

It will replace the present silicon tracker with 7 layers of Monolithic Silicon Active Pixel Sensors (MAPS) and significantly improve the detector performance in terms of tracking and rate capabilities. The choice of technology has been guided by the tight requirements on the material budget of 0.3 X$_{0}$ for the three innermost layers and backed by the significant progress in the field of MAPS in recent years. The new ITS will in total cover a surface of 10.3 m$^2$ with approximately 25 $\times$ 10$^9$ pixels. The pixel chips are manufactured in the TowerJazz 180 nm CMOS imaging sensor process on wafers with high resistivity epitaxial layer. Within the ongoing R&D phase, several sensor chip prototypes have been developed and produced on different epitaxial layer thicknesses and resistivities. These chips are being characterised for their performances before and after irradiation using source tests, test beam and measurements using an infrared laser. The present contribution will provide an overview of the ALICE ITS upgrade with a focus on the R&D activities on the pixel chip.

In particular, the Pixel detector is inserting an additional inner layer called Insertable B-Layer (IBL). The Readout-Driver card (ROD), the Back-of-Crate card (BOC), and the S-Link together form the essential frontend data path of the IBL’s off-detector DAQ system. The strategy for IBLROD firmware development focused on migrating and tailoring HDL code blocks from PixelROD to ensure modular compatibility in future ROD upgrades, in which a unified code version will interface with IBL and Pixel layers. Essential features such as data formatting, frontend-specific error handling, and calibration are added to the ROD data path. An IBLDAQ testbench using realistic frontend chip model was created to serve as an initial framework for full offline electronic system simulation. In this document, major firmware achievements concerning the IBLROD data path implementation, tested in testbench and on ROD prototypes, will be reported. Recent Pixel collaboration efforts focus on finalizing hardware and firmware tests for IBL. Time plan is to approach a final IBL DAQ phase by the end of 2014.

Cherenkov photons emitted within a 1 cm thick quartz radiator are propagated by internal reflection and imaged on to an array of Micro-Channel Plate photomultiplier tubes (MCPs). Performing 3$\sigma$ pion/kaon separation at the limits of this momentum regime requires a time-of-flight resolution per track of 10-15 ps, over a ~10m flight path. With ~30 detected photons per track the required single-photon time resolution is ~70 ps. This presentation will discuss the development of the TORCH R&D program and present an outline for future work. Summary TORCH (Time Of internally Reflected CHerenkov radiation) is a highly compact Time-of-Flight (ToF) system utilizing Cherenkov radiation to achieve particle identification up to 10 GeV/c. At the upper limit of this momentum, a 10-15 ps resolution per track is required to achieve a 3$\sigma$ ToF difference between pions and kaons. TORCH will consist of a 1cm thick radiator plate equipped with light guides along the top and bottom of the plate which focus the produced Cherenkov radiation onto a series of micro-channel plate photomultipliers (MCPs). Precise timing of the arrival of the photons and their association with a particle track is then used to determine the particle time-of-flight. Around 30 photons are expected to be detected per track which results in a required time resolution per photon of around 70 ps. The time of propagation of each photon through the plate is governed by its wavelength which affects both its speed of propagation and its Cherenkov emission angle, and by measuring this angle to 1mrad precision TORCH will correct for chromatic dispersion. The performance of the system relies on the MCP combining fast timing and longevity in high radiation environments, with a high granularity to allow precise measurement of the Cherenkov angle. Development of a 53 mm x 53 mm active area device with 8x128 effective pixel granularity, sub 50ps time resolution and long lifetime is under way with an industrial partner as part of the TORCH development. A GEANT-4 simulation of the TORCH detector and its performance is currently being developed, taking accounting for the contributions to the overall TORCH resolution. This talk will focus on the requirements of the TORCH design and R&D developments including progress toward a prototype and the development and laboratory tests of the MCP.

Currently its Pixel-Detector is being upgraded with a new innermost 4th layer, the Insertable b-Layer (IBL). The upgrade will result in better tracking efficiency and compensate radiation damages of the Pixel-Detector. Newly developed front-end electronics (FE-I4) will require a complete re-design of the Off-Detector- Electronics consisting of the Back-Of-Crate card (BOC) and the Read-Out-Driver (ROD). The main purpose of the BOC card is the distribution of the LHC clock to all Pixel-Detector components as well as interfacing the detector and the higher-level-readout optically. It is equipped with three Xilinx Spartan-6 FPGAs, one BOC Control FPGA (BCF) and two BOC Main FPGAs (BMF). The BMF are responsible for the signal processing of all incoming and outgoing data. The data-path to the detector is running a 40 MHz bi-phase-mark encoded stream. This stream is delayed by a fine delay block using Spartan-6 IODELAY primitives. The primitives are reconfigured using partial reconfiguration inside the FPGA. The 160 MHz 8b10b-encoded data-path from the detector is phase and word-aligned in the firmware and then forwarded to the ROD after decoding. The ROD it will send out the processed data which is then forwarded to the higher-level readout by the BOC card. An overview of the firmware, which has been developed, will be presented together with the results from production tests and the system test at CERN. One focus will be the partial reconfiguration and the results of the fine delay measurements. Summary For the new innermost layer of the ATLAS Pixel-Detector at CERN new off-detector hardware needs to be developed. The Back-Of-Crate card (BOC) is driving the optical interface to the detector and distributing the LHC clock to all detector components. A brief overview of the firmware and test results from production and system test will be presented.

The new sub-detector, named Insertable B-layer (IBL), will be installed between the existing Pixel Detector and a new smaller radius beam-pipe at a radius of 3.3 cm. To cope with the high radiation and pixel occupancy due to the proximity to the interaction point, a new read-out chip and two different silicon sensor technologies (planar and 3D) have been developed. Furthermore, the physics performance will be improved through the reduction of pixel size while targeting for a low material budget should be imposed, pushing for a new mechanical support using lightweight staves and a CO2 based cooling system.

For the PID system in the forward region of the spectrometer, a proximity focusing RICH counter with aerogel radiator is being developed. For this counter we have devised a focusing radiator consisting of two aerogel layers with increasing refractive index along the particle path, which results in a focusing of Cherenkov light at the photon detector plane. In this way, a thicker radiator can be used, and the number of photons can be increased without degrading the single photon Cherenkov angle resolution. The detector will provide a $4~\sigma$ separation of pions and kaons up to momenta of 4 GeV/c, at the kinematic limits of the experiment. The main challenge was, however, a reliable multichannel sensor for single photons that operates in the high magnetic field of the spectrometer (1.5 T) and withstands the radiation levels expected in the experiment. A 144-channel Hybrid Avalanche Photo-Detector (HAPD) was developed in a collaboration with Hamamatsu Photonics K.K. The design of the detector components is currently being finalized and part of the mass production has already started. The counter will be ready for installation in 2015. We will report on the tests of the prototypes conducted with test beams at CERN and DESY, and the optimization and performance studies of the counter final design, based on the Geant4 simulation.

We used a 1 liter PTFE chamber observed by an array of 7 large area SiPMs (Hamamatsu S11828-3344M) covering about the 4% of the internal surface. The chamber is lined with a reflective foil (VIKUITI) evaporated with a wavelength shifter (TetraPhenyl Butadiene). This solution allows to convert the UV photons to the visible band, thus matching the SiPM sensitivity window while maximizing light collection. The measured light-yield is comparable with the highest light-yield values obtained in similar conditions using standard 3" cryogenic PMT's (Hamamatsu R11065) for a 3 times higher photo-cathodic coverage. The present result, combined with the other well known intrinsic SiPM advantages (compact design, contained costs, low bias voltage,… ) represents a step forward in the confirmation of the SiPM technology as a real alternative to standard PMT-based read-out systems for application in cryogenic noble liquid detectors.

LZ will be deployed at the 4850-ft level of the Sanford Underground Research Facility (South Dakota, USA) after completion of LUX, which is presently operating there. At its core, LZ will feature a 7-tonne (active) liquid xenon TPC surrounded by two ‘veto’ detectors. Particle interactions in the WIMP target generate two signatures: prompt scintillation light and ionisation charge, the latter transduced to a pulse of electroluminescence light in a thin gaseous layer above the liquid. Our strategy is to mitigate radiogenic backgrounds from detector materials through a combination of self-shielding, precise vertex location, coincidence vetoing, and xenon purification – to expose a uniform background from astrophysical neutrinos. Electron recoils from solar pp neutrino scattering can be mostly discriminated by the ratio of the two signatures, which differs from that for nuclear recoil interactions expected from WIMPs. We present the project status and the sensitivity reach of this exciting instrument due to start construction soon.

A $^{96}$Zr nuclei has a large Q-value (3.35MeV), and no experiment is planned to use as a target. In order to realize ton scale target isotope with good energy resolution (4\%(a)2.5MeV), we have used zirconium beta-diketon complex which has huge solubility (over 10w.t.\%) to the Anisole. However, the absorption wavelength of diketon ligand overlaps with the luminescence from Anisole. Therefore, the light yield of liquid scintillator decreased in proportion to the concentration of beta-diketon complex. In order to avoid this problem, we synthesized beta-keto ester complex introducing -OC3H7 or -OC2H5 substituent groups in the beta-diketon complex. These complexes have shorter absorption wavelength (245nm) than the emission wavelength of Anisole (275nm). The scintillation light yield recoverd about double, however, did not reach at the expected value, because the residual absorption around the 275nm still exists. We found those were caused by the imprities of beta-keto ester complex and it will be solved by thr purifying the complex. Now we have also found that a diethyl malonate ligands shifted the absorption peak to around 210nm, and the complex will have no quenching for the Anisole based liquid scintillator. Here we will report the present status.

The increase in luminosity will produce a higher particle background with respect to present conditions. Performance and stability of detectors at LHC and future upgrade systems will remain the subject of extensive studies. The current CERN-Gamma Irradiation Facility (GIF) has been intensively used to simultaneously expose detectors to the photons from a 137Cesium source and to high energy particles from the X5 beam line in SPS West Area for many years. From 2004 onwards, only the 137Cesium source is available for irradiations and the shutdown of the present facility is scheduled for the end of 2014. The present contribution describes a joint project between CERN-EN and CERN-PH departments to design and build the new CERN GIF++ facility. GIF++ will be a unique place where high energy charged particle beams (mainly muon beam with momentum up to 100 GeV/c) are combined with a 14 TBq 137Cesium source. The higher source activity will produce a background gamma field which is a factor 30 more intense than that at GIF, allowing to cumulate doses equivalent to HL-LHC experimental conditions in a reasonable time. The 100 m2 GIF++ irradiation bunker has two independent irradiation zones making it possible to test real size detectors, of up to several m2, as well as a broad range of smaller prototype detectors and electronic components. The photon flux of each irradiation zone will be tuned using a set of Lead filters with attenuation factors from zero to 50000. Flexible services and infrastructure including electronic racks, gas systems, radiation and environmental monitoring systems, and ample preparation zone will allow time effective installation of detectors. A dedicated control system will provide the overview of the status of the facility and archive relevant information. The collaboration between CERN and the users’ detector community, the latter providing detector specific infrastructures within the framework of the FP7 AIDA project, will bring the new facility to operation by the end of 2014.

The heart of HEC read-out electronics is the pre-amplifier and summing (PAS) system, which is realized in GaAs ASIC technology. These PAS devices are installed inside the LAr cryostats, directly on the detector. They have been proven to operate reliably in LHC conditions up to an integrated luminosity of 1000 fb$^{-1}$, including safety factors. However, at the HL-LHC a total integrated luminosity of 3000 fb$^{-1}$ is expected, which corresponds to an increase of a factor of 3-5 in the expected radiation levels. On top of this, a safety factor of at least 2 needs to be accounted for to reflect our confidence in the background rate simulations. Samples of the GaAs ASIC have therefore been exposed to neutron and proton radiation with integrated fluences in excess of 4x10$^{15}$ n/cm$^2$ and 2.6x10$^{14}$ p/cm$^2$, several times the levels expected for ten years of HL-LHC running. In-situ measurements of S-parameters allow the evaluation of frequency-dependent performance parameters, like gain and input impedance. The non-linearity of the ASIC response has been measured both at warm and at cold, i.e. at LAr temperatures. This allows an improved estimation of the expected degradation of the HEC performance. The measured gain and non-linearity of the ASIC response have been applied to Monte-Carlo simulations in order to understand their effects on jet measurements in HL-LHC conditions.

Summary A feasibility study of a 3-inch Vacuum Silicon Photo Multiplier Tube Introduction The Vacuum Silicon PhotoMultiplier Tube (VSiPMT) is an innovative design that we propose the first time at the 11th Topical Seminar on Innovative Particle and Radiation Detectors (IPRD08) in Siena, triggering deep discussions on the feasibility of the device itself and on the convenience of such an idea. The basic idea is to replace the classical dynode chain of a PMT with a SiPM, which acts as an electron multiplying detector. Such a solution will match the goal of a large photocathode sensitive area with the performances of a SiPM. This will lead to many advantages such as lower power consumption, mild sensitivity to magnetic fields and high quantum efficiency. The feasibility of this idea has been thoroughly studied both from a theoretical and experimental point of view. As a first step we performed the full characterization of a special non-windowed Hamamatsu MPPC with a laser source. The response of the SiPM to an electron beam was studied as a function of the energy and of the incident angle by means of a Geant4-based simulation. After this firsts results Hamamatsu accepted to considered the idea and built, expressly for us, two prototypes for testing purposes. In this work, we present some results of the full characterization of the first two prototypes of VSiPMT. Both devices exhibit very attractive features, such as low power consumption, weak sensitivity to magnetic fields, high resolution in the pulses height giving so excellent photon counting capability. owever, the two prototypes made by Hamamatsu presents a photocathode of only 3 mm in diameter. In order, for these innovative devices, to be competitive, compared to traditional PMT (e.g. in areas such as underwater neutrino telescopes or dark matter search experiments), it was necessary to study the feasibility of a 3-inch VSiPMT. This study was based mainly on the electron beam focus on the SiPM surface. As will be shown, the linearity and the efficiency of the VSiPMT can be affected by poor electron focusing on the MPPC. For this reason, the focusing system requires special attention with the respect of classical PMTs. Will be present COMSOL simulations (figure 3) of a possible solution for the electron beam focusing trying to keep the external dimensions of the device similar to those of a classical 3-inch PMT. We are confident that the realization of the VSiPMT will start a revolutionary generation of photo- detectors for near‐future applications. Moreover, fields like medical equipment, physical checkup and diagnosis (e.g. Radioimmunoassay and Enzyme immunoassay), biomedicine, environmental measurement equipment, oil well logging, all will require further improvements in photon detection performances, as linearity, gain, quantum efficiency improvement and single photon counting capability. We believe that the proposed device has the potential to fulfill these requirements.

See below a detailed summary of your submitted abstract: Conference: Tipp 2014 - Third International Conference on Technology and Instrumentation in Particle Physics Submitted by: VIVOLO, Daniele Submitted on: 25 February 2014 16:36 Title: Test on VSiPMT prototypes Abstract content Vacuum Silicon PhotoMultiplier Tube (VSiPMT) is an innovative photodetector based on the combination of SiPM and PMT technologies. The basic idea consists in replacing the classical dynode chain of a PhotoMultiplier Tube with a SiPM. Such a design was proposed by our group in order to match the goal of a large photocathode sensitive area with the unrivalled photon counting performances of SiPMs. Moreover, much more improvements with respect to the standard PMT technology are expected to be obtained by VSiPMTs. First of all, the absence of the standard dynode chain will lead to avoid using voltage dividers and, hence, to a much lower power consumption. Transit Time Spread is expected to be sensibly reduced, since there will be no dynode chain spread, while Single Photoelectron resolution and gain stability will be much improved. In the proposed configuration, the SiPM acts as an electron multiplying detector. Therefore, the proof of feasibility of VSiPMT has required a thorough study both from a theoretical and experimental point of view. The extremely encouraging results obtained by our group led us to a new, advanced phase, consisting in the test of some VSiPMT prototypes realized by Hamamatsu. Our results show that VSiPMT prototypes performances go far beyond our expectations, thus charting the course for the development of an unrivalled innovative photon detection technology. In the present work we will describe accurately the results of our tests on Hamamatsu prototypes and we will show our studies and our purposes for the optimization of the device. Summary The detection of (single) photons is an essential experimental tool for a wide range of research areas. To date, in astroparticle physics experiments based on Cherenkov detectors a crucial role has been played by photomultiplier tubes. PMT technology has been improved continuously in the last years: the quantum efficiency of the photocathode has now reached a level of 40%, close to the theoretical maximum; single photon sensitivity and time resolution have been improved by a careful design of electrostatic focusing on the 1st dynode; with new coatings the secondary electron yield of dynodes has greatly improved, reducing the required number of dynodes and their size. Nevertheless standard photomultiplier tubes suffer the following drawbacks: • fluctuations in the first dynode gain make single photon counting difficult; • linearity is strongly related to the gain and decreases as the latter increases; • transit time spreads over large fluctuations; • mechanical structure is complex, voluminous, rather massive and expensive; • they are sensitive to magnetic fields. Moreover, in low background experiments the radioactivity of the photomultiplier components is a key concern. In fact, in many applications PMTs can dominate the total radioactivity of the detector. A significant effort is being made by manufacturers and research teams in order to reduce the background from photomultiplier tubes by rigorous choice of the raw materials used for all components. However, significant traces of radioactive nuclei are encountered in the metal and ceramic parts of the electron multiplication system. Hybrid photodetectors, not using dynode structures for amplification, are an attractive solution. In fact, in this type of device photoelectrons emerging from the photocathode are focused onto a silicon detector. As silicon is virtually free of radioactivity and the mass of the photodiode can be very small, the background from the inner part of the tube can be significantly reduced. The Vacuum Silicon PhotoMultiplier Tube (VSiPMT) is an innovative photodetector based on the combination of SiPM and PMT technologies. The basic idea consists in replacing the classical dynode chain of a PhotoMultiplier Tube with a SiPM. Such a design was proposed by our group in order to match the goal of a large photocathode sensitive area with the unrivalled photon counting performances of SiPMs. Moreover, much more improvements with respect to the standard PMT technology are expected to be obtained by VSiPMTs. First of all, the absence of the standard dynode chain will lead to avoid using voltage dividers and, hence, to a much lower power consumption. Transit Time Spread is expected to be sensibly reduced, since there will be no dynode chain spread, while Single Photoelectron resolution and gain stability will be much improved. Differently from standard hybrids based on APDs, in the VSiPMT the HV between the photocathode and the silicon device is limited to 2-4 kV. Moreover, this HV is needed for the transportation of the photoelectrons and to make them overcome the SiO2 coating layer covering the SiPM. Therefore, the photoelectrons need a much lower voltage to be detected by a SiPM. The multiplication given by the SiPM is independent of the kinetic energy of the photoelectrons, as the output signal of a SiPM is independent of the number of electrons/holes created by the photoelectron in the same cell and is instead proportional to the number of cells fired. Several studies have been performed in last years by the INFN Napoli group on this subject. On the base of the very encouraging results obtained by our group, a first prototype of the VSiPMT has been developed in collaboration with Hamamatsu and tested in our labs. The measured performances are extremely encouraging. The work function of the VSiPMT has been evaluated showing a good linearity with satisfactory gain output G=(3÷6)·105. This prototype showed extremely good photon counting capabilities thanks to the very good performance in terms of SPE resolution (<17%), peak-to-valley ratio (> 60) and Transit Time Spread (< 0.5 ns). With an optimized design, the VSiPMT will exhibit several attractive features such as: • excellent single photon detection; • high gain; • small electron amplification system size; • negligible power consumption; • low radioactivity background; • weak dependence on magnetic fields; • small price with respect to PMTs; • good performance at low temperature. In this work we will provide an accurate description of the prototypes and of the extremely encouraging results of our tests. Moreover, we will show our studies and our purposes for the optimization of the device.

These two conditions imply that future experiments will take place in very high radiation areas. In order to perform these complex and perhaps expensive experiments new radiation hard technologies will have to be developed. Chemical Vapor Deposition (CVD) diamond has been developed as a radiation tolerant material for use very close to the interaction region where detectors must operate in extreme radiation conditions. During the past few years many CVD diamond devices have been manufactured and tested. As a detector for high radiation environments CVD diamond benefits substantially from its radiation hardness, very low leakage current, low dielectric constant, fast signal collection and ability to operate at room temperature. As a result CVD diamond has now been used extensively in beam conditions monitors at every experiment in the LHC. In addition, CVD diamond is now being considered as a sensor material for particle tracking detectors closest to the interaction region where the most extreme radiation conditions exist. We will present the present state-of-the-art of polycrystalline CVD diamond and single crystal CVD diamond and the latest results on the radiation tolerance of these materials for a range of protons, pions and neutrons obtained from strip detectors constructed with these materials.

See below a detailed summary of your submitted abstract: Conference: Tipp 2014 - Third International Conference on Technology and Instrumentation in Particle Physics Submitted by: KRIEGER, Peter Submitted on: 25 February 2014 15:23 Title: Upgraded readout and trigger electronics for the ATLAS liquid argon calorimeters for future LHC running Abstract content The ATLAS Liquid Argon (LAr) calorimeters produce almost 200K signals that must be digitized and processed by the front-end and back-end electronics at every triggered event. Additionally, the front-end electronics sums analog signals to provide coarse-grained energy sums to the first-level (L1) trigger system. The current design was optimized for the nominal LHC luminosity of 10$^{34}$cm$^{-2}$s$^{-1}$. However, in future higher-luminosity phases of LHC operation, the luminosity (and associated pile-up noise) will be 3-7 times higher. An improved spatial granularity of the trigger primitives is therefore proposed, in order to improve the trigger performance at high background rejection rates. For the first upgrade phase in 2018, new LAr Trigger Digitizer Boards are being designed to receive the higher granularity signals, digitize them on-detector and send them via fast optical links to a new digital processing system (DPS). This applies digital filtering and identifies significant energy depositions in each trigger channel. The refined trigger primitives are transmitted to the L1 system, allowing extraction of improved trigger signatures. This talk will present the concept for the upgraded readout and describe the components being developed for the new system. R&D activities as well as architectural and performance studies will be described, as will details of the on-going design of mixed-signal front-end ASICs, radiation tolerant optical-links, and the high-speed FPGA-based DPS units. These studies also guide the way towards the second upgrade phase, in which all LAr Calorimeter read-out electronics must be replaced due to radiation damage, ageing, and a new ATLAS trigger scheme.

The electromagnetic calorimeters use lead as passive material and are characterized by an accordion geometry that allows a fast and uniform response without azimuthal gaps. Copper and tungsten were chosen as passive material for the hadronic calorimetry; while a classic parallel-plate geometry was adopted at large polar angles, an innovative design based on cylindrical electrodes with thin liquid argon gaps is employed for the coverage at low angles, where the particle flux is higher. All detectors are housed in three cryostats maintained at about 88.5K. The approximately 200,000 cells are read out via front-end boards housed in on-detector crates that also contain calibration, trigger and timing boards. The talk will focus on the design and performance of the detector during the first three years of LHC operation, during which approximately 27 fb$^{-1}$ of pp collision data were collected at centre-of-mass energies of 7-8 TeV. Throughout this period, the calorimeter consistently operated with performances very close to specifications, with a data-taking efficiency greater than 99% in 2012. The high efficiency is in part due to sophisticated data monitoring infrastructure designed to quickly identify issues that would degrade the detector performance, to ensure that only the best quality data are used for physics analysis.
