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. | ||||||||
