Near term work plan

Update on INFN GEM layers for GEn-RP

  • Ran up a new divider on the front layer GEM of the inline stack. Verified temperature and V/I consistent with divider run-up with no GEM.
  • Currently in Hall. Plan to install new dividers on upstream-most layer while we can easily access. Will need sliding platform to remove the layer to install the new dividers on the second layer.

Update on UVa GEM layers for GEn-RP

  • UVA GEM HDMI, HV and LV cables are all connected both from the detector side and crate sides.
  • The order of gas sut-off valves arrived and we have connected them and start flushing the GEMs with Nitrogen since Monday.
  • Plan to do a HV test on UVA GEM sometime early next week.

Update on BB GEMs

  • Cosmic data taken last week and alignment in progress
  • Need to get the new HV on the main HV GUI and added in EPICS

DAQ updates (Ben, Bryan, Alex)

  • schematic of setup?
  • FIR filter?
