DESCRIPTION:Speakers: Paul Colas (CEA/Irfu Université Paris Saclay)\nSign
 ificant R&D on detectors for the future International Linear Collider (ILC
 ) has been carried out during the last few years. The ILD central tracker 
 includes a Time\nProjection Chamber (TPC) embedded in a 3.5 T solenoidal f
 ield. \nWithin the framework of the LCTPC collaboration\, a Large Prototyp
 e (LP) TPC has been built\nas a demonstrator. Its endplate can accommodate
  up to seven modules of MPGD representative of the proposed design for ILD
 . The MPGD technologies being developed are Gas ElectronMultiplier (GEM)\,
  Micromegas and GridPix. In these technologies\, two solutions for the gas
  amplification (GEM and Micromegas) are combined with either a traditional
  pad-based or a digital chip readout.\n\nA large prototype of TPC\, equipp
 ed with up to seven identical modules in a 1 T magnetic field has been tes
 ted with a 6 GeV electron beam at DESY. Track reconstruction performance w
 as measured for three different detector technologies: Gas Electron Multip
 lier\, Resistive Micromegas and GridPix. Recent results of these tests wil
 l be given. They address realistically implementation questions. Also\, to
 gether with the ILD collaboration\, a detailed study of the field configur
 ation in the interaction region and its effects on the background is start
 ed\, and plans for calibration and alignment are drawn up. The current sta
 tus of these will be reported.  \n\nIt was demonstrated that current techn
 ologies allow us to meet the ILD tracker requirements.\n\nhttps://indico.i
