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
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
