CsI(Na) crystals at temperatures of ~-100 ℃ have the best performance in several candidate crystals. An experiment called CINDMS is proposed for WIMPs direct searches based on the CsI(Na) crystals detector by IHEP. The 1T-scale experimental threshold is expected to be in the world advanced level through the background estimates. The initial stage of a 50kg scale experiment called CINDMS50 is under construction at Daya Bay neutrino experiment underground laboratory for the accumulation of technology. CINDMS1T or more large-scale experiment may be located deep underground laboratory of Jinping Mountain in Sichuan, China. This location provides vastly improved shielding from cosmogenic events which will reduce interference of known backgrounds particles.

We propose a novel front-end architecture aimed at reducing dead time by introducing multi signal paths in each pixel cell. A prototype chip using 0.18um six-metal standard CMOS process is consisting of 16 x 16 pixels. Each pixel has 200um pixel pitch and contains two signal paths. Two preamplifiers, eight comparators, three 15-bit counters, switching circuits, and a 30um x 30um input pad are included in a pixel. Each preamplifier has feedback capacitor and feedback resistor. We use a transistor as a feedback resistor to control its resistivity. When the preamplifier integrate charge from the input pad, the gate voltage of the transistor is lower than threshold voltage to have high resistivity. After readout the input current pulse, the transistor is turned on for fast reset. The two preamplifiers are connected to the input pad via the switching circuit respectively. The switching circuit allows only one preamplifier to connect the input pad at a time. After current pulse coming to one amplifier through the switching circuit, the switching circuit changes its connection to reduce dead time of a pixel. Each output of the two preamplifiers feed four comparators with different thresholds respectively. These four comparators perform quantization of the preamplifier output amplitude to distinguish incident X-ray photon energy. The chip will be fabricated in June 2014 and post layout simulation results will be presented in TIPP 2014.

See below a detailed summary of your submitted abstract: Conference: Tipp 2014 - Third International Conference on Technology and Instrumentation in Particle Physics Submitted by: TEH, Lloyd Submitted on: 29 January 2014 00:28 Title: Fine Segmented Scintillator ECAL Abstract content The idea of using scintillator strips coupled with Pixelated Photon-Detector(PPD) has provided the ILD an electromagnetic calorimeter(ECAL) option with a lower cost. In the FNAL 2009 beam test, it was found that the prototype calorimeter of 30 layers could meet the stringent requirements of the ILD. Following this, efforts has been made to develop a more feasible ECAL in terms of performance, size and cost. With a more compact readout electronics and improved PPD, 2 layers of embedded front end electronics technological prototype was fabricated using 3 layers of 180x180mm^2 ECAL base unit(EBU), in which each EBU has 144 channels of 45x5mm scintillator strip coupled with the improved PPD. The two layers are arranged orthogonally and by using the Strip Splitting Algorithm(SSA), we could create a fine granularity of 5x5mm^2 for the Particle Flow Algorithm application. The layers were tested at DESY and the results of this beam test shall be presented. In addition, various studies has been made on the scintillator strip in order to further improve the ScECAL’s performance such as to reduce the dead volume by PPD etc. The findings of these studies shall also be discussed and compared with the simulation results. Summary The ScECAL technological prototype shows no significant problems operating in a multilayer configuration and the SSA works well. The results from the beam test shows good energy deposit, low noisy or dead channel ratio and good scintillator uniformity. By modifying the scintillator strip shape and configuration, these performance can be further improved.

The detector is comprised of tightly-packed optically-isolated water tanks, each 5m tall and 7.3m in diameter, which are instrumented with 4 Hamamatsu photomultiplier tubes. This allows the PMTs detect the secondary charged particles that are produced when high energy (100 GeV - 100 TeV for HAWC) gamma rays and cosmic rays interact with the atmosphere. Though the detector is under construction, the DAQ has been operating and expanding with the detector as tanks are added. The DAQ is designed to handle a final event trigger rate of >15 kHz with high uptime (>99%) and low latency (<5 s), while also analyzing events with multiple triggers and reconstruction algorithms in real time. This is achieved using a modular system based on inexpensive hardware components and open source technology for transferring data (ZeroMQ). This flexible framework is agnostic to the type of data that is transferred and it could easily be applied to other experiments. We will explain the motivation for this design, describe the DAQ in detail, and present the performance of the detector.

The new promising neutrino programs request the higher performance of the detectors. It is proposed to increase the photoelectron detection efficiency of the PMT used in neutrino experiment. The researchers in IHEP designed a new type of MCP-PMT. The small MCP unit instead of the large Dynode, the transmission photocathode and the reflection photocathode were assembled in the same glass shell to form nearly 4 pai photocathode effective area to enhance the efficiency of the photoelectron detecting. Some researchers and engineers in institutes and companies in China come together to manufacture and research this type of PMT based on the MCPs. After two years R&D work, several 8 inch prototypes were produced and there performance was carefully tested in our Lab. The MCP-PMT performance test system was built in our Lab for better performance test. The characteristics of the photocathode were carefully researched by testing the I-V curve, the QE, and the QE-map for the 8 inch area photocathode uniformity. Also we measured the charge spectrum to confirm its ability for the single photoelectron spectrum. More simulation and experiment work have already done to develop an 8 inch prototype module for the MCP-PMT designed in IHEP, and the detailed will be described in this formal manuscript.

These considerations, together with the physics needs and beam structure of CLIC, push the technological requirements to the limits and imply a very different vertex detector than the ones currently in use elsewhere. A detector concept based on hybrid planar pixel-detector technology is under development for the CLIC vertex detector. It comprises fast, low-power and small-pitch readout ASICs implemented in 65 nm CMOS technology (CLICpix) coupled to ultra-thin sensors via low-mass interconnects. The power dissipation of the readout chips is reduced by means of power pulsing, allowing for a cooling system based on forced gas flow. In this talk, the CLIC vertex-detector requirements are reviewed and the current status of R&D on sensors, readout and detector integration is presented.

Laser mass spectrometry is one of the most beneficial applications of this detector, but these detectors can be successfully used in other areas where one-dimensional spatial detection of charged and neutral particles is required. In general dimensions and resolving capacity of the detector are determined by collector’s number which collects the electrons charge, its dimension and pitch. Each collector has its own charge to digit converter completed bodily on one semiconductor chip. Charge to digit conversion mechanism is defined by direct calculating charge’s portions (number of electrons) drops to collector. To ensure that sensitivity allows registering of individual ions, the detector has an integrated assembly of two microchannel plates arranged in front of the surface of the receiving electrodes. Structurally, the detector is designed as a ceramic-based monoblock, which is mounted on the chip detector assembly of microchannel plates and the necessary interface connectors. Overall dimensions of the detector assembly is 40x25x5mm. Size of the sensitive area is 2x10mm.

Abstract content The best jet energy resolution required for precise physics measurements at ILC is achievable using a Particle Flow Algorithm (PFA) and highly granular calorimeters. As it was shown by CALICE international R&D collaboration, the silicon-tungsten imaging electromagnetic calorimeter provides the best granularity and jet resolution. After proving the PFA concept with physical prototypes in 2006-2011, an emphasis is now moved to building a technological prototype satisfying challenging physical, mechanical, electronic and thermal requirements. All chosen technologies should be reliable and scalable for a mass production of a future detector. We report on the current status of R&D, in particular, on beam, cosmic and charge injection tests of the technological prototype and on the tests of ECAL mechanical structure with embedded fiber Bragg grating optical sensors. We also report on our plans to build a realistic almost full-scale prototype detector of 1-1.5 m length and test it together with an existing 600 kg carbon fiber - tungsten mechanical structure in 2015 at CERN beams.

See below a detailed summary of your submitted abstract: Conference: Tipp 2014 - Third International Conference on Technology and Instrumentation in Particle Physics Submitted by: FUENTES ROJAS, Cristian Alejandro Submitted on: 28 January 2014 17:07 Title: A power-pulsing scheme for the CLIC vertex detector and its 3D integration Abstract content The vertex detector is the innermost detector at the proposed CLIC linear electron-positron collider. It is composed of several layers of pixel sensors and readout ASICs, and the barrel region is made of “ladders”. The precision physics requirements limit the material budget for sensors, readout, support, cooling and cabling to less than 0.2% of a radiation length (X0) per detection layer. However, the power consumption of the readout electronics strongly impacts the required low material budget of the detector. To reduce the cable and cooling material, the average power per unit area has to be small (<50 mW/cm^2). The collision at CLIC will occur in bunch crossings every 0.5 ns during a bunch train of 156 ns. The time between consecutive trains is approximately 20 ms. Turning on the readout ASICs during the bunch trains and keeping them idle in the other part of the cycle will therefore significantly reduce the average power dissipation. The use of this beam duty cycle to reduce the average power is known as power-pulsing. The use of a power-pulsing scheme implies that the ASIC current consumption has to change suddenly from its idle value (few hundreds of mA) to full load (more than 40 Amps for a single ladder composed of 24 ASICs) within a few microseconds, then remain constant for enough time to record and process the events (few tens of microseconds) and finally drop back to the idle current value. During the bunch train, the power consumption is at its maximum and constant, and the supplied voltage for the analog components has to remain within 5% of the nominal voltage in order to allow for a correct functioning of the readout ASICs. The latter is particularly challenging, considering the big transient that takes place before the readout process. The analog and digital components of the ASICs have different constraints and therefore will be powered separately. A power-pulsing scheme based on a controlled current source allows achieving a material contribution of 0.1% of X0, which is expected to be reduced as the silicon capacitors technology improves. It consists of a controlled back-end current source that charges silicon capacitors in the ladder with low current during the idle time. In this way, the charging current is reduced to less than 100 mA for a whole ladder. The charge accumulated in these capacitors is then delivered to the ASICs during the bunch crossing time and the voltage is regulated using Low Dropout Regulators (LDOs). A prototype of this back-end current source was implemented using an FPGA. A dummy load emulating the power consumption of the analog and digital components has been implemented. In order to consolidate the proposed scheme the integration of such a system was studied. This implementation requires the use of through silicon vias, silicon capacitor die structures, and 3D connections to an LDO and a low mass interconnection cable. This talk will present the proposed powering scheme and the possible solutions of the 3D integration problem.
