Its innovative approach is that it uses a compact annular 300 mm long Time Projection Chamber (TPC) surrounding a thick cylindrical liquid hydrogen target. The TPC reconstructs the recoiled proton tracks in order to locate the interaction vertex inside the target, allowing a proper Doppler correction to emitted gamma rays measured in a dedicated detector. A bulk-micromegas, segmented in 4608x2 mm2 pads, is used to readout the TPC which is filled with an Argon-iC4H10(3%)-CF4(15%) gas mixture. The electronics is composed of 20 analog front-end cards. Each of these is read out by a newly designed digital board, called the Feminos, which is compatible with the AFTER and AGET chips. The internal and external TPC field cages are made of 2 mm thick Rohacell cylinders on which are glued 50 microns thick Kapton foils printed with 381 copper strips. The MINOS device will be described, with a focus on the design choices and performances of the TPC characterized in laboratory with cosmic rays. We will report on the recent full in-beam validation of the TPC at HIMAC (Japan) where a better than 4 mm vertex resolution was obtained with a 180 and 350 Mev/u 20Ne ion-beam impinging on 0.5 mm thick CH2 and C targets.

It enables new detector designs, like the Time-of-Propagation DIRC of Belle II, or the TORCH upgrade for LHCb, and to improve existing designs, e.g. allow chromatic corrections in DIRCs. These applications have in common a high channel density, limited available space and low power consumption. We report on Frontend Electronics developed for the PANDA Barrel DIRC. The customised design utilises high-bandwidth pre-amplifiers and fast discriminators providing LVDS output signals which can be directly fed into the TRBv3 readout using FPGA-TDCs with a precision better than 20ps RMS. The discriminators also provide Time-over-Threshold (ToT) information which can be used for walk corrections thus improving the obtainable timing resolution. Two types of cards, optimised for reading out 64-channel Photonis Planacon MCP-PMTs, were tested: one based on the NINO ASIC and the other, called PADIWA, on FPGA-based discriminators. Both types feature 16 channels per card, thus requiring four cards to read out one 64-channel MCP-PMT. Power consumption for the complete readout of one Planacon MCP-PMT is approx. 10W for the NINO FEE and approx. 5W for the PADIWA FEE. The timing performance of the cards was tested with a fast laser system and also in a test experiment at the MAMI accelerator in Mainz using a small DIRC prototype to image Cherenkov patterns. In both cases, using the ToT information, a timing resolution of better than 100ps was found for the complete readout chain.

There are three candidate photodetectors; One is a 20-inch venetian blind dynode type PMT (R3600) which is used in Super-Kamiokande. Second is a newly developed box and line dynode type PMT which has a better collection efficiency and timing response than R3600. The other one, a large-aperture Hybrid Photo-Detector (HPD), is also newly developed and uses an avalanche diode instead of dynodes to multiply photoelectrons. Compared to PMT, the HPD has a simpler structure, better collection efficiency, better timing response, and better single photoelectron charge resolution. A high quantum efficiency (QE) is a common option for the three candidates and it was applied for the R3600 at first. The high-QE R3600 has 30 % QE at maximum peak, 1.4 times higher than that of the R3600 used in Super-Kamiokande. In order to evaluate the performance and usability of the candidate photodetectors, we perform a long-term test with a 200-ton water Cherenkov detector located in Kamioka mine. The progress of the long-term test of 8-inch HPDs and high-QE R3600s will be reported. The status of R & D of the 20-inch box & line PMTs and 20-inch HPDs will be also presented. We plan to choose the photodetectors for Hyper-K in 2016.

Thus this camera has a potential of developing the new reagents for molecular imaging. Until now we have carried out several imaging reagent studies such as : (1) F-18-FDG (511keV) and I-131-MIBG (364keV) for double clinical tracer imaging, (2) Zn-65(1116keV),Mn-54, Fe-59 in mouse for high energy gamma emitting RI imaging. In addition, ETCC can image continuum spectral gamma-rays by removing background particle using dE/dx of the track. ETCC has a potential of real-time monitoring of the Bragg peak location by detecting prompt gammas. We successfully obtained the images of both 511keV and continuum high energy gamma rays (800-2000keV) from the water target irradiated by 140MeV proton (Kurosawa, Cur. Apl. Phys, 12 (2012), pp. 364). In 2013 we have completed a 30cm cube ETCC to catch gamma-rays, of which tracking efficiency was improved with 10 times. It enables to select the Compton event contained in TPC using only the energy loss rate of the track with distinguishing it from all backgrounds. Eventually its sensitivity is improved by a factor of 100. A similar imaging test for prompt gammas using 140MeV proton beam was recently carried out, of which intensity was increased more 10 times than previous experiment. Here I present new performance of the improved ETCC and the results of the beam test.

See below a detailed summary of your submitted abstract: Conference: Tipp 2014 - Third International Conference on Technology and Instrumentation in Particle Physics Submitted by: YAO, Yuan Submitted on: 31 January 2014 08:12 Title: A Method of Frequency-tracking in Direct Detection Doppler Wind LIDAR Abstract content The Direct Detection Doppler Wind LIDAR (DWL) is of great significance in the study of global wind measurements and climatology. The DWL adopting double-edge technique of Fabry-Perot etalon requires outgoing laser frequency to fall on the abrupt linear region of the transmittance curve of F-P etalon. Vibration and temperature variation would cause frequency shift, which will further induce laser frequency to fall outside the linear region. While the precision and sensitivity of DWL greatly lowered, a locking channel is hereby designed for shift detection. According to the shift, the position of transmittance curve can be modulated, which guarantees the frequency falling on the linear region. An approach of detecting the frequency shift is to measure amplitude variation by Photomultiplier Tube (PMT). The output signal is periodic, with 50Hz in frequency, only 20ns-width and sharp edges. Consequently, it is difficult to measure amplitude of such a narrow pulse signal under relatively low sampling rate. To reduce the error caused by low sampling rate, the measurement of the pulse area is made to instead of pulse amplitude. Statistical methods are also applied for further accuracy and improving stability. A data acquisition system including circuit and a specific software is designed. The system includes external trigger, data acquisition and processing. Controlling system sends trigger parameters and acquisition commands via software. Tests using splitters have been carried out. The ratio results indicate consistent between the data acquisition system and commercial oscilloscope. The results with relative error of 0.80% also meet the locking requirements.

By measuring the track of an electron, ETCC measures the direction of gamma-rays as a small arc, which provides a good background rejection using the kinematical test and energy loss rate of the track (particle identification), and clear imaging. Already we revealed its strong background rejection ability by the balloon experiment (a 10cm-cube ETCC: SMILE-I) in 2006, where 98% background events were removed. In 2013 we completed a 30cm cube ETCC to catch gamma-rays from Crab in next SMILE-II balloon experiment with >5shigma for several hours. The tracking efficiency was improved with 10 times, which enables to select the Compton event in TPC using only the energy loss rate of the track with distinguishing it from all backgrounds. Thus, we can extract the maximum detection efficiency expected by the simulation. Also SPD angle provides a several times better contract in image than conventional Compton method. Then, SMILE-II would provide a 5times better sensitivity than COMPTEL with the use of 3atm CF4 gas, and 40cm-cube ETCCs onboard satellite is expected to reach near 10-12 ergcm-2s-1. To verify this performance, SMILE-II was irradiated by secondary gammas and neutron from water target using 140MeV proton beam, and measured the clear image of a weak source under 10times stronger radiation than that in the balloon altitude. Here we will present the detail of the SMIEL-II performance including this beam test.

This MCP-PMT has high photon detection efficiency which results from using transmission photocathode and reflection photocathode simultaneously, and the total quantum efficiency reaches approximately 30%. Good design of focusing electrode and appropriate distribution of voltage can ensure 95% photoelectrons entering the surface of MCP. The electron multiplication system consists of 4 MCPs that each of the two pieces of MCP is a component, by optimizing the voltages of each MCP and the gaps between MCPs, the gain obtained is greater than 107 and the peak to valley ratio of single photoelectron is about 2. For anode optimization, we design two kinds of configuration to reduce signal ringing, the one is metal mesh and plate, the other is micro-strip line. Finally, by using signal cable which impedance matches the anode, we obtain very single photoelectron signal.

The following email has been sent to YUREVICH, Vladimir: === Dear Vladimir Yurevich, The submission of your abstract has been successfully processed. Abstract submitted: <https://indico.cern.ch/userAbstracts.py?confId=192695>. Status of your abstract: <https://indico.cern.ch/abstractDisplay.py?abstractId=121&confId=192695>. See below a detailed summary of your submitted abstract: Conference: Tipp 2014 - Third International Conference on Technology and Instrumentation in Particle Physics Submitted by: YUREVICH, Vladimir Submitted on: 31 January 2014 06:29 Title: Modular Detector with Picosecond Time Resolution Abstract content Nowadays the TOF measurement with picosecond time resolution is important feature in high-energy physics experiments and the detectors solving this task are important part of experimental setups. The initial point of our activity in this direction was a proposal of Fast Forward Detector (FFD) for MPD/NICA project [1]. The detector concept and results obtained with the first version of detector modules were published in [2]. Another considerable application is developing a modular array for BMN project [3]. Both these cases were studied by MC simulation and some the results are presented here. Application in experiments with rather low energy of heavy ions, sNN1/2 ~ a few GeV, is the most difficult case because in such collisions the produced particles have the smallest multiplicity and mostly their velocities β are essentially less of 1. The examples are novel experiments CBM at SIS-100, BMN at Nuclotron, and MPD/NICA which are in preparation stage. In this report the experience in developing and testing modules for detector arrays with picosecond time resolution based on registration of Cherenkov radiation induced by relativistic charged particles and high-energy photons is described. The important point for ps-timing and operation in magnetic field is application of MCP-PMTs XP85012/A1-Q from Photonis. The main idea of the detector concept is registration of ultrarelativistic charged particles and high-energy photons by conversion to electrons in lead layer in front of quartz radiator. The total active area of the module is 59 × 59 mm with zero dead space (only module housing defines the dead area). It is very important point because it allows designing detector arrays without any dead space. The module has four independent cells/channels. The quartz radiator has 15-mm thickness and it is segmented into four bars. The radiator is optically coupled with MCP-PMT which has 8 × 8 anode pads transformed into 2 × 2 cells by merging 4 × 4 pads of each cell into a single channel. The FEE is carried out amplification and formation of output analog and LVDS signals. The performance of detector modules and modular arrays proposed for start signal generation in TOF measurements and triggering Au + Au collisions in MPD/NICA and BMN was studied by MC simulation and in tests with GeV single-charged ions of Nuclotron beam and cosmic rays. In the experimental tests three different types of readout electronics were used: (i) measurement of time and amplitude with TAC and ADC, (ii) determination of time and pulse width for LVDS signals, and (iii) analysis of pulse shape by digitizing with 200-ps/bin time scale. For single-charged particles with β ≈ 1 producing about 1800 Cherenkov photons in quartz, the module channel generated the pulses with pulse height of ~ 300 mV, rise time of 1.2 ns, pulse width of 5 ns at noise level of a few mV. The time resolution obtained in the measurements with two modules is ~ 30 ps (sigma) per module cell. It means that one may hope to get an excellent time resolution better than 10 ps in a real experiment where registration of a large number of charged particles and photons by modular array occurs in single events. 1.
