CTA will study the highest-energy particle accelerators in the Universe and potentially confirm the particle nature of dark matter. We have designed an innovative Schwarzschild-Couder telescope which uses two mirrors to achieve excellent optical performance across a wide field of view. The small plate scale of the dual-mirror optics enables a compact camera which uses modern technology including silicon photomultipliers and the TARGET application-specific integrated circuit to read out a finely pixelated focal plane of 11,328 channels with modest weight, volume, cost, and power consumption. The camera design is hierarchical and modular at each level, enabling robust construction, operation, and maintenance. A prototype telescope is under construction and will be commissioned at the VERITAS site in Arizona. An array of such telescopes will provide excellent angular resolution and sensitivity in the core energy range of CTA, from 100 GeV to several TeV.

Abstract content The Large Area Picosecond Photo-Detector Collaboration (LAPPD) is currently developing a large-area, modular photo-detector system composed of thin, planar, glass-body modules, each with two 20cm x 20cm ALD-functionalized MCPs in a chevron geometry. The collaboration is working closely with industry partner Incom inc., towards the commercialization of this technology. One of the major challenges has been to successfully seal a top window to the hermetic glass package module. The collaboration is pursuing multiple sealing techniques; one a hot solder sealing technique and a second thermo-compression sealing technique. In this talk, I will present results from a thermo-compression seal of a top window to a 20cm x 20cm glass package module with a pump out port for leak checking the seal and describe the path towards commercialization of the 20cm x 20cm devices with Incom, Inc. As an intermediate step towards building a full system for making 20cm x 20cm devices, but independent from the LAPPD collaboration, Argonne has also developed a small form-factor (6cm x 6cm) photodetector development facility consisting of a four vacuum chamber system: loadlock, bake and scrub chamber, photocathode deposition chamber, and sealing chamber. Successful thermo-compression sealing of the 6cm x 6cm photodetector prototypes at the Argonne development facility has been accomplished in the sealing chamber. The entire system has recently undergone a bakeout and is currently achieving an ultra-high vacuum base pressure throughout the system with photocathode fabrication underway. An overview of results from the first working 6cm x 6cm active area detectors based on the ALD micro-channel plate, all glass body technology will be presented as available.

See below a detailed summary of your submitted abstract: Conference: Tipp 2014 - Third International Conference on Technology and Instrumentation in Particle Physics Submitted by: FIORINI, Massimiliano Submitted on: 28 February 2014 22:09 Title: CLARO-CMOS: a fast, low power and radiation-hard front-end ASIC for single-photon counting in 0.35 micron CMOS technology Abstract content The CLARO-CMOS is a prototype ASIC that allows fast photon counting with 5 ns peaking time, a recovery time to baseline smaller than 25 ns, and a power consumption of about 1 mW per channel. This chip is capable of single-photon counting with multi-anode photomultiplier tubes (Ma-PMTs), and finds applications also in the read-out of silicon photomultipliers and microchannel plates. The prototype is realized in AMS 0.35 micron CMOS technology. In the LHCb RICH environment, over ten years of operation at the nominal luminosity expected after the upgrade in Long Shutdown 2, the ASIC must withstand a total fluence of about 6x10^12 1 MeV neq/cm2 and a total ionizing dose of 400 krad. A systematic evaluation of the radiation effects on the CLARO-CMOS performance is therefore crucial to ensure long-term stability of the electronics front-end. The results of multi-step irradiation tests with neutrons up to the fluence of 10^14 1 MeV neq/cm^2, with protons up to the dose of 8 Mrad and with X-rays up to the dose of 8 Mrad are presented, including measurement of single event effects during irradiation and chip performance evaluation before and after each irradiation step. In addition, systematic tests have been done on the single-photon counting performance of the CLARO-CMOS coupled to a Hamamatsu R11265 Ma-PMT, that is the baseline solution for the upgraded LHCb RICH photo-detectors. Such results are presented as well. Summary The CLARO-CMOS is a prototype ASIC primarily designed for single-photon counting with multi-anode photomultipliers (Ma-PMTs). The chip allows fast photon counting up to 40 MHz with power consumption in the order of 1 mW per channel. It was developed in the framework of the LHCb RICH detectors upgrade at CERN, but also found application in the readout of Silicon photomultipliers (SiPMs) and microchannel plates (MCP-PMTs) [1,2]. The prototype has four channels, each made of a charge amplifier with settable gain (3 bits) and a comparator with settable threshold (5 bits) that allow tuning the response of the chip to the gain spread of the PMT pixels. The threshold can be set just above noise to allow an efficient single-photon counting with Ma-PMTs. In the readout of SiPMs, the threshold can be set above the single photon signals, allowing to count events with two or more photoelectrons with high efficiency and good separation of the photoelectron peaks. The prototype is realized in a 0.35 micron CMOS technology. In the LHCb RICH environment, over ten years of operation at the nominal luminosity for the upgrade, the ASIC must withstand a total fluence of about 6x10^12 1 MeV neq/cm^2 and a total ionizing dose of 400 krad. We present results of multi-step irradiation tests with neutrons up to the fluence of 10^14 1 MeV neq/cm^2, with protons up to the dose of 8 Mrad and with X-rays up to the dose of 8 Mrad. During irradiation, cumulative effects on the performance of the analog parts of the chip and single event effects (SEE) were evaluated. The chips were biased continuously and the chip threshold voltages were measured regularly, in order to detect possible single event upsets (SEUs) affecting the threshold DAC settings. Power consumption was also monitored online, and an additional circuit provided protection against Single Event Latchup (SEL). A picture of one of the irradiation setups can be seen in Figure 1. S-curves were measured before and after each irradiation step, to follow the evolution of counting efficiency, threshold shifts and noise during the irradiation. ![Figure 1. Picture of the setup used to irradiate three CLARO-CMOS chips at the neutron irradiation line of the Université Catholique de Louvain Cyclotron Facility (Louvain-la-Neuve, Belgium). The visible cables are used for powering and configuring the chips, monitoring single event effects on-line and measuring chips performance][1] [1]: https://dl.dropboxusercontent.com/u/63884889/louvain.png **Figure 1.** Picture of the setup used to irradiate three CLARO-CMOS chips at the neutron irradiation line of the Université Catholique de Louvain Cyclotron Facility (Louvain-la-Neuve, Belgium). The visible cables are used for powering and configuring the chips, monitoring single event effects on-line and measuring chips performance. The electrical performances of the CLARO-CMOS chip coupled to the Hamamatsu R11265 Ma-PMT are presented as well. For these tests a dedicated PCB was designed to connect the chips to the Ma-PMT with minimal contribution of parasitic capacitances at the input, and allowed to obtain very low noise and crosstalk. This readout scheme simulates the baseline read-out solution for the upgraded RICH detectors of the LHCb experiment. To mimic the conditions expected in the upgraded LHCb RICH environment, single photons in the blue range were generated using LED and diode laser. The speed of the CLARO signals and the low power consumption were demonstrated. Single-photon spectra from the Ma-PMT pixels were nicely reconstructed with a threshold scan, showing that the binary outputs allow precise characterization of the Ma-PMT. Also, crosstalk between neighboring pixels was shown to be negligible. References: [1] P.

The devices has been irradiated with neutrons in three dose steps: 5x10^8 1MeV-neutron equivalent (neq), 5x10^9 neq and 5x10^10 neq. After each irradiation step the characteristic current-voltage curves and a high statistics sample of the dark noise waveforms have been recorded for offline analysis. In the proposed contribution we will present the results on the variation of the main SiPM parameters as a function of the dose for the devices under study, that include as well special “Radiation Hard” designs. Summary Silicon Photo Multipliers (SiPMs) are novel solid state photon detectors based on matrices of Geiger mode APDs. The interest of the scientific community for these devices has constantly increased since their (recent) development, thanks to their very appealing characteristics. They can in fact guarantee the same performances of standard vacuum tube photo multipliers with many advantages: single photon counting capability, compactness (few mm), low bias voltage (< 100V) , insensitivity to magnetic fieds etc… They have also a few drawbacks though, like the high dark noise rate and the radiation damage, which cause a degradation of the main parameters (i.e. gain, dark noise, photon counting capability…). The first issue has been addressed by the manufacturers, with significative improvements in the last years. The radiation damage is, instead, an intrinsic effect that is of paramount importance to understand, especially for applications where a high radiation environment is expected (like in High Energy Physics experiments). SiPMs producers are prototyping new devices to face this issue and it is very important to have a feedback from the final users. In the proposed contribution we will present results of the irradiation test of 16 SiPMs from Hamamatsu, including non commercial “Radiation Hard” devices. The sample under study is made of 16 SiPMs with the same geometrical parameters (a square 1x1 mm2 active area and 50μm pixels) but realized with 8 different constructive methodologies (2 SiPM per type). The devices have been irradiated with neutrons in Leuven la Neuve at the CRC-CYCLONE 110 facility, with integrated 1 MeV equivalent doses of: 5x10^8 neq, 5x10^9 neq and 5x10^10 neq. (values where is maximum the rate of change of the performances.). The experimental setup consisted of: a custom made PCB, for the mechanical support, bias and readout of the SiPMs signals; a commercial National Instrument CompactRIO system, for the readout of the currents and of the temperature; a high performances waveform digitizer (5GS/s, 12 bits) and a Keithley picoammeter for the I-V curves. After each irradiation step and for each device, we measured the current versus voltage (I-V) characteristic curve and, thanks to the high resolution wavewform digitizer, we stored a high statistics (100 k-events per SiPM) sample of dark noise signals. The offline analsysis of the above data will allow us to measure the change in the main parameters of the devices: dark current, dark noise (rate and spectra) and, possibly, the gain (for the latter parameter, it can be measured as long as the single photo electron peaks are visible). The results of the above measurements will be presented.

The current status and future plans of this program will be presented, with an emphasis on recent results from the Liquid Argon Purity Demonstrator (LAPD). Removing electronegative impurities from liquid argon is crucial for the operation of liquid argon time projection chambers (LArTPC). An important milestone for future large LArTPC detectors was the demonstration that electron lifetimes greater than 2 ms can be obtained in two cryostats that cannot be evacuated: the LAPD and the LBNE 35 ton prototype membrane cryostat. A TPC with a 2 meter drift was operated in the LAPD cryostat, and the electron lifetimes measured by the purity monitors are compatible with those measured by the TPC.

The LAPPD collaboration is developing 20$\times$20 cm$^2$ glass-body micro-channel plate (MCP) photomultiplier tubes equipped with an economical 1.5 GHz, 30-channel microstrip anode to extract the MCP signals. The PSEC4 chip, a 6-channel 0.13 $\mu$m CMOS waveform digitizer, was designed by the Universities of Chicago and Hawai'i as a first generation readout ASIC for these photosensors [1]. A PSEC4-based DAQ system that is capable of reading out a number of LAPPD MCPs was subsequently developed by our group. The system architecture incorporates two levels of hardware, FPGA-embedded system control, and data processing. At the front-end is a 30 channel unit that holds five PSEC4 ASICs and a control FPGA that plugs directly into one terminal of the LAPPD MCP anode. The analog bandwidth of the signal input is 1.5 GHz. In order to record waveforms at both ends of the LAPPD anode, two of these cards are required to fully instrument an LAPPD MCP. The back-end card houses the system control FPGA, distributes the system clock, and manages up to four front-end units by means of eight 800 Mbps LVDS lines. This back-end card communicates to a PC using USB 2.0 or gigabit Ethernet. The system performance and LAPPD detector-integrated testing results will be presented. [1] NIM A732, p452, Jan 2014.

Their main advantages are high gain, low operational voltage, insensitivity to magnetic fields, robust and compact design. Their big disadvantage for single photon detection is their high dark count rate, which is of the order of 0.1-1 MHz/mm$^2$. We have however already measured and demonstrated that 1mm x 1mm SiPMs (Hamamatsu MPPC S10362-11-100P ) can be used a sensor of single photons if the acquisition time window is narrow enough to reject most of the background hits. A progress in the last several years has made available the SiPMs with much lower background per unit area, which enables the use of SiPM with larger pads and increase the sensor geometrical acceptance. We have studied a module based on a Hamamatsu MPPC S11834 8x8 SiPM array of 3 mm x 3 mm SiPMs. To increase the geometrical efficiency the 5mm x 5mm $\to$ 3mm x 3mm quartz light collectors were used. In the contribution, a bench and beam tests of the module will be presented.

During that time, the CDF silicon vertex detector was subject to radiation doses of up to 12 Mrad. After the end of operations, the silicon detector was annealed for 24 days at 18 degrees celsius. A method for monitoring the bias current and depletion voltage of the sensors was developed, and the measurement of the time evolution of these quantites during annealing are in agreement with expectations from the Hamburg model. This monitoring method has the potential to alert today's experiments when the beneficial effects of annealing, that happen on short time scales, are complete and allow them to stop the annealling process before the harmful or reverse annealing effects, that happen on longer time scales, become significant.

MCPs can be used in wide variety of applications such as imaging spectroscopy, photodetectors for high energy physics and astronomy, time-of-flight mass spectrometry, molecular and atomic collision studies, and cluster physics. The same MCP-based technology is used to make visible light image intensifiers for night vision devices. Through the Large Area Picosecond PhotoDetector (LAPPD) program based at Argonne, we developed a cost-effective and robust Atomic Layer Deposition (ALD) nano-composite thin film technology to fabricate large-area (8”x8”) microchannel plates. Here we have tailored the electrical resistance and secondary electron emission (SEE) properties of large area, low cost, borosilicate glass micro-capillary arrays to produce MCPs with high gain, low noise and long life. We have developed several robust and reliable ALD processes for the resistive coatings and SEE layers to give us precise control over the resistance in the target range for MCPs (10e6-10e9) and SEE coefficient (up to 8). These MCPs were found to provide high gains of up to 10e7 (chevron pair). Here, the latest developments in the ALD nano-composite materials will be presented.
