  1. TPCs for High Energy Physics David Attié Max Chefdeville ,Paul Colas, Arnaud Giganon, Marco Zito, Ioannis Giomataris, François Pierre, Jin Li, Yulan Li, Huirong Qi, Zhenwei Yang CPPM Marseille 17 January 2008 FCPPL, Marseille – January 17th, 2008

  2. Overview • Introduction • The LC-TPC R&D Collaboration • Saclay-Tsinghua University  TPCs R&D for HEP collaboration • Saclay & Lanzhou interests • Conclusion FCPPL, Marseille – January 17th, 2008

  3. Micromegas & GEMs (MPGD) 50 µm 40 kV/cm ~1000 µm 1 kV/cm ~50 µm 80 kV/cm Technology choice for Linear Collider TPC: Micro Pattern Gaseous Detector • No E×B effect • better ageing properties • more robust than wires • easier to manufacture GEM Micromegas • simplicity • single stage of amplification • natural ion feedback suppression • discharges non destructive • 2- or 3- stage amplification • easy operation • low field above the electronics • low discharge probability FCPPL, Marseille – January 17th, 2008
