  1. News from Micromegas modules D. Attié, P. Colas, M. Riallot LCTPC WP Meeting #82 7 May 2009 Micromegas module

  2. Back from GEM to Micromegas • We dismounted the GEM module and mounted the new Micromegas module with resistive ink and the new electronics enable_shaping=false option • We also tightened some loose screws suppressing leaks • We installed the updated software for the new electronics and tested it Micromegas module

  3. Cosmics with new detector & electronics Micromegas module

  4. Signal from new electronics (cosmics) • Signal at the central pad showing • the exponential tale characteristic • of no shaping • Signal at the neighboring pad Micromegas module

  5. Schedule for next beam test • TPC Analysis Jamboree 2009: May 11th -14th (no one from DESY?) • Plans for data taking: • May 18th-20th: fiber and laser installation and commissioning, flush with gas • May 21th-24th: commissioning of detector with cosmics at B=0 • May 25th start data taking at B=1T • Around May 28th : change module to C-loaded kapton • June 2nd: end of data taking Micromegas module
