Main topic

Update on INFN GEM commissioning (Evaristo, Roberto)

Evaristo could not attend the meeting today. Below is his updates from email

  • My colleagues in Catania re-tested a second GEM foil that did not passed the Quality Check in 2015. We left dry nitrogen flushing for more than 1 full day. The new test has been passed: all sector currents at 550->450 V are well below 10 nA.
  • thanks to Bogdan suggestions we prepared a new version of the GEM installation procedure (still draft), that I will distribute to Todd probably tomorrow. Essentially we are coming back to the hypothesis of using a portable crane instead of an installation stand (which would require design and manufacturing).

Update on the Tracking efficiency / resolution (Andrew)

Update on UVa GEM commissioning (Kondo, Anu)

High Rate MPD readout / DAQ (Danning)

MPD decoder software (John)

Update on PREX GEM (Siyu)
