Difference: FJPPLDetectorRD (16 vs. 17)

Summary :
This is a proposal to start a new series of R&D on liquid xenon as detectors of the gamma ray applied to PET (Positron Emission Tomography) technology by the SUBATECH Laboratory (http://www-subatech.in2p3.fr/en/research/nuclear-and-health/xenon/about), Ecole des Mines de Nantes, and KEK (http://rd.kek.jp/project/LXe/index_e.html). Recently SUBATECH group has established a technology to measure a small ionization signal in liquid xenon by using a dedicated electronics coupled to readout pads though ceramic feedthough connectors. In parallel in Japan new photo sensors for the use in liquid xenon temperature to measure its scintillation light are being developed with finer segmentations; Avalance Photo diode (APD), SiPM, and multi-anode photomultipliers. These new technologies are supported by developments made in a series of R&D ever performed by the SUBATCH-KEK collaboration. The proposal is addressing concrete tests on prototypes located both at KEK and Suabtech; they will focus on the understanding of liquid xenon properties for medical imaging. In parallel, the groups will prepare the next experiment XEMIS2 which will be installed in 2015 at the Nantes hospital to image small animals

Summary :
This project is a collaboration of Japanese SOI sensor group and French OMEGA microelectronics group. In this project we will develop new photon image sensors by using a Silicon-On-Insulator (SOI) technology and readout ASICs/modules for photon detectors. SOI pixel detector has been developed in KEK Detector Technology Project mainly for charged particle tracking and X-ray imaging. By combining linear mode avalanche process and SOI-CMOS signal processing power, we are aiming to develop high-sensitivity image sensors for visible light and low-energy X-ray. We also develop readout ASICs and modules for photon detectors such as APD or PPD (SiPM) mainly by the OMEGA group. The OMEGA group has rich experience in developing readout ASICs. By collaborating these groups, new photon detection system for many scientific researches will be realized.
