It is expected to reach an order of magnitude better sensitivity than has been achieved so far by the best experiments in the field. The technical challenges of commissioning a payload of this size have led to the development of 1.4 kg germanium detectors (100 mm diameter, 33 mm thick), which are 2.3 times larger than those presently in use in the SuperCDMS experiment at Soudan. The first results from testing of a prototype detector with interleaved phonon and charge channels are presented. The test results are promising for the use of these detectors in the next phase of SuperCDMS. Summary Primary Authors: Dr. CHAGANI, H.

However a key problem of low count rates need to be tackled. A noval geometry and scintillator architectures with the AMOC spectrometer is designed to promote the spectrometer count rates. A well-shape BaF2 scintillator is employed to detect the 1.28MeV gamma photon emmitted while the generation of a positron, which improves the cross section by about three times. By placing the HPGE detector behind the photomultiplier tube in the line, HPGE detectecor can still capture the 0.511MeV gamma photon emmitted while the annihilation of a positron.A new hard trigger system is designed and utilized to reduce the dead time. The spectrometer with high efficiency is on debugging for better performance.

It has been designed to achieve an excellent Jet Energy Resolution by using Particle Flow Algorithms (PFA), which rely on the ability to separate nearby particles within jets. PFA requires calorimeters with high granularity. The ILD Electromagnetic Calorimeter(ECAL) is a sampling calorimeter with thirty tungsten absorber layers. The total thickness of this ECAL is about 20 centimeters, and it has between 10 and 100 million channels to make high granularity. Silicon sensors are a candidate technology for the sensitive layers of this ECAL. Present prototypes of these sensors have 256 5.5x5.5 mm^2 pixels in an area of 9x9cm^2. 　　　 We have measured various properties of these prototype sensors: the leakage current, capacitance, and full depletion voltage. We have also examined the response to an infrared laser to understand the sensor's response at its edge and between pixel readout pads, as well the effect of different guard ring designs. We will report on the results of these basic measurements of silicon sensor. Summary We have established a silicon sensor test bench system to measure leakage current and capacitance. The results of these measurements satisfy the requirements for the ILD ECAL. We have also studied the effects of the guard ring and inter-pixel gap by using a laser system.

The proximity-focusing A-RICH system is especially designed to identify charged pions and kaons by the use of aerogel Cherenkov radiators with refractive indices of 1.045 and 1.055 and to have a separation capability of greater than 4σ at momenta up to 4 GeV/c. We plan to fill the large end-cap region of 3.5 m^2 with 124 segmented dual-layer-focusing aerogel combinations (248 tiles in total). It is crucial to minimize the number of aerogel tiles (i.e., to maximize the aerogel dimensions) to reduce tile boundaries, because the number of detected photoelectrons decreases at the boundaries. Therefore, we have developed a method for producing 18 × 18 × 2 cm^3 large area, transparent aerogels with no cracking. Prepared aerogel tiles will be trimmed in fan shapes according to the cylindrical end cap with a water jet cutter, making the best use of the hydrophobic features. Mass production was started in September 2013 and is going on track. Here we report the status of optical characterization of mass-produced aerogels in addition to the results of a beam test with a prototype A-RICH counter conducted at DESY, Germany in advance of mass production.

This counter is designed to be used at the forward endcap region and to have pion/kaon separation with more than 4-sigma deviations at momenta up to 4 GeV/c. 144-channel Hybrid Avalanche Photo-Detector (HAPD) modules developed with Hamamatsu Photonics K.K. have been adopted as the photon detectors for the A-RICH. A total of 420 HAPD will be used in Belle II detector. We started the mass production of the HAPD. Quality of the manufactured HAPD is checked by a system that we developed. We report the status of the quality check that consists of the leakage current measurement, channel-by-channel noise level measurement, the 2-dimensional scan for photon detection, and the quantum efficiency measurement for the photo cathode. As for the readout of about 60,000 channels from the A-RICH, we developed an ASIC for the amplification and digitization of the signal from HAPDs. We started the mass production of the ASIC last year. Then we plan to test all the ASIC chips before mounting them on the front-end boards attached to HAPDs. The data from several front-end boards will be merged into one board, and are sent to the Belle II central DAQ system by an optical link called Belle2Link. For this purpose, modules called "merger board" located inside the detector are under development. Each merger board is connected to 6 front-end boards, and has an FPGA for the data merging and transmission. We are developing the firmware for the FPGA and testing it. In this presentation, status of the mass production of HAPDs and ASICs, and the development and test results for the merger board will be reported.

How do these fundamental degrees of freedom dynamically generates the mass, spin, motion and spatial distribution of color charges inside hadrons ? To investigate these fundamental question new electron proton and electron ion colliders are proposed (EIC). The inner tracking system of the detectors in these colliders will require very high granularity, low material budget and radiation hard design. In this talk will be shown some of the studies done for eRHIC: a EIC facility with polarized electron and proton beams, unpolarized ion beam, to be realized in the Brookhaven National Laboratory. This talk will focus mainly on the studies and performance simulations realized for the inner silicon tracking system and on the possibility of using Monolithic Active Pixel Silicon detector (MAPS) as silicon sensor.

The thermal management of the system will be provided by evaporative CO2 circulating in microchannels embedded within thin silicon plates. This solution has been selected due to the excellent thermal efficiency, the absence of thermal expansion mismatch with silicon ASIC’s and sensors, the radiation hardness of CO2, and very low contribution to the material budget. Although microchannel cooling is gaining considerable attention for applications related to microelectronics, it is still a novel technology for particle physics experiments, in particular when combined with evaporative CO2 cooling. The R&D effort for LHCb is focusing on the design and layout of the channels together with a fluidic connector and its attachment to withstand pressures in excess of 200 bars. This talk will describe the design and optimization of the cooling system for LHCb together with latest prototyping results. Even distribution of the coolant is ensured by means of the use of restrictions implemented before the entrance to a race-track layout of the main cooling channels. The coolant flow and pressure drop has been simulated together with the thermal performance of the device. The results can be compared to the cooling performance of prototype plates operating in vacuum. The design of a suitable low mass connector, together with the bonding technique to the cooling plate will be described. Long term reliability as well as resistance to extremes of pressure and temperature is of prime importance. The setup and operation of a cyclic stress test of the prototype cooling channel designs will be described. Summary The status and R&D for microchannel cooling for the LHCb VELO upgrade will be described, as outlined in the abstract above.

The LAPPD glass tile module was designed to be simple, with: a) a hermetic package made of top and bottom plates and a rectangular sidewall, each made of water-jet-cut plate glass; b) an internal stack consisting of 2 glass capillary plates functionalized with Atomic Layer Deposition and 3 glass grid spacers made from waterjet-cut plate glass; and a getter assembly that drops into place. Features of the design are: no pins penetrating the envelope; c) an internal HV divider implemented by resistive coatings on the MCP's and spacers; d) RF-stripline anodes silkscreened on the bottom plate with an analog bandwidth above 1.5 GHz for good spatial and temporal resolution; e) mechanical rigidity provided by atmospheric pressure; and f) modular design for covering large areas. The tile is one component of a modular system in which an array of four tiles sits on a 1800-square-cm `Tray' section that contains the ground plane of the RF strip-lines and supports the waveform sampling and data-acquisition electronics that reads out the strips.

The prototype is being designed in the same 0.13um IBM-8RF CMOS process as the PSEC4 ASIC [1]. The major improvements are the increase of the storage buffer from 256 cells to 32,768 cells per channel, allowing a trigger latency of ~3.3us at 10GS/sec, and an increased readout rate. The input signal is continuously sampled into a Primary Array with 256 capacitors which, for a 100ns sampling rate, is rewritten every 25.6ns. The sampling pulses are generated by a Voltage-Controlled Delay Line in 256 stages, run as a Delay-Locked Loop (DLL). The deep Storage Array is organized as two arrays, each 128 capacitors wide by 128 deep. The contents of each half of the Primary Array are transferred into the Storage Array at fixed time intervals in an alternate fashion. The writing and reading of the Storage Array is done with full external control. The design allows uninterrupted writing of the Storage Array after a trigger by selecting a region-of-interest for read-out and temporarily removing it from the recording chain. Depending on the size of the region-of-interest window, the dead time can be greatly reduced or eliminated. The sampled signals are digitized on-chip, and read out serially. The design status and simulation results will be presented. 1.
