<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 being intensively worked on, including 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_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.
