<center>D_RD_09 : *Toward the final design of a TPC for the ILD detector* </center>

_Summary_: <br>
The D_RD_02 project allowed a ‘proof of principle’ of MPGDs (Micromegas and GEMs) for the electron amplification and readout of a TPC for the Linear Collider. The resolution of such an apparatus was understood and shown to be adequate, and the operation in a beam was demonstrated.
Since 2013, a new project was started, as a preparatory step toward the construction of a TPC for the ILD experiment. Integration aspects are now fully addressed: cooling, distortion mitigation and correction, electronics design, gating and other issues, as well as the definition of criteria for the technology choice.<br>

<center>D_RD_11 : *Prototype development of a positron emission tomography detector using liquid Xenon* </center>

_Summary_ :<br>
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

<center>D_RD_14 : *Development of photosensor with SOI technology* </center>

_Summary_ :<br>
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.

<center>D_RD_15 : *Innovative design concepts in P doped bulk planar pixel sensors* </center>

_Summary_ :<br>
Our aim within the FJPPL is to develop and improve, around French and Japanese collaborators at LAL Orsay, KEK and Tsukuba University, respectively, a strong expertise on tracking detectors for future experiments, with international visibility. The detector upgrade programs underway in ATLAS for HL-LHC will be occasions to improve and optimize the planar pixel technology, which is a particularly well established technology for vertex detectors. The challenge consists in building more granular and thinner P doped sensor devices while keeping the goal of achieving cost effective solutions for large surfaces of sensitive material. This technology, even if it is mature, still needs to prove sufficient radiation hardness in the innermost region, close to the HL-LHC beam crossing environment. The activity within the project includes several of the critical tasks needed to develop this technology.
