GMn GEM commissioning Meetings: WEDNESDAY 10:00am - 11:00am

Link to all previous meetings: GMn GEM Commissioning Meeting

Update on INFN GEM commissioning (Evaristo, Roberto, Ezekiel)

Update on UVa GEM commissioning (Kondo & Anu)

  • Soldered the 85% divider into the modules that were recently put into the cosmic stand (i.e the first 3 layers in the cosmic stand)

Update from cosmic data (Malinga & Thir)

Update on the Tracking efficiency / resolution (Andrew)

Update on the High rate DAQ development (Ben, Alex, Paolo, Holly)

  • Able to read out all installed MPDs in BB setup in a stable configuration except for MPD in slot 13. 66 APVs total including the 5 in the test setup. Will troubleshoot the MPD in slot 13 and connections. Ben doing firmware updates.
  • New firmware updated in SSP and MPD to support VME2eSST320 (320MB/s) and supports much faster event building. Firmware is running on BB setup and saturates the 1Gbps ethernet. Next the data needs to be verified. The system ran at 1.1kHz trigger rate with no zero suppression and 118MB/s. Enabling zero suppression will reduce the data rate and allow higher rates to be reach (2.7kHz should be the limit if there is an MPD with 15APV).
