  • 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).
