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).
