  • Update
    • Ecal
      • DAQ running : DMA was not working for VTP, seems to work with register - VTP data can be readout, taking cosmics data with cluster feature and comparing. Check FADC and VTP data cross checking. Will adjust timing of VTP
      • Ecal will be opened until Tuesday for adding additionnal cooling
      • some data recorded : VTP matching with FADC on the small amount of data
      • add HCAL next week in DAQ - less work to do
      • add print statement for sync reset
      • coincidence trigger ready : pulser to test from HCAL and ECAL - Ecal cosmics, Ecal auxiliary, Cluster, same for HCAL + HCal and Ecal coincidence - need lookup table from Kip - firmware support all of them - Chandan and Jiwan looking into setting up pulse
      • All Ecal FADC channel ok - One FADC removed - 2 FADCs need to be repaired - 0 spare right now - Moller/Compton has 2 or 3 FADCs
      • v3 need driver and firmware ~ summer - Moller has a few v3 - does not support trigger - use Hall D firmware - Hai working on up to date version combining - no charge scalers - no diag guy - no pulse trigger mode -
    • GEM
      • 10 gig fiber issue on going
      • 2 stuck APV, replaced but still issue
      • MPD transceivers : all look OK - no MPD not connecting lately - stick with this transceiver
      • 15 hour run - 2 or 3 M events wih random pulser with no crash
      • LV : EPICS variable for readback - supply has webserver
      • CM danning -
    • CDet
      • took cosmics - see hits
      • HV debugging
      • need to send signals to VETROC : RF, trigger ...
    • Beamline
      • updated firmware for FADC - can start run for sbsvme29
      • still need to add helicity in read out list - Paul will look at it early next week - need to write decoder - should be straightforward
      • configuration beam - on with TS and need to make one stand alone
      • need to plug back fiber for LHRS beamline crate - and will make config with both
      • test with helicity board of whole system ? Can easily verify decoder decoder sequence matches what is coming form scalers - Check helicity bits match with FADC - take one BCM signal from VtoF and can patch reported helicity for test - could test after APS
      • need to check spot++ for BPM
