  • Updates
    • HCAL
      • Taking data with overlap region trigger with different thresholds
      • testing DAC, patch panel received, not able to get any output so far. Some channels voltage changed but cannot control. Need to look more at it with Bryan.
      • writing GUI to control the DAC
    • Bigbite shower
      • with current noise with MIP from pions, best approach is take data in mode 1 rather than mode 7
      • still need to test F1 TDC
    • Bigbite hodoscope
      • taking data smoothly
      • threshold study for NINO cards
      • working on documentation
      • no issues
    • GRINCH
      • Gasket material delivered, will install next week, GRINCH open this week
      • continuing on software and documentation. VETROC data ok still working on ADC
      • issue with ROC decoding of ADC - might be missing a header for decoding - might need to adjust the read out list - intelvmeha6 - Mark / Bradley will look at making rol similar to hodoscope
    • LHRS
      • cabling detectors with Maria
      • copy Bigbite shower FADC library over to HRS so can use
      • Fastbus was missing a slot, flag word in detec
    • GEM TEDF
      • upgraded resistors on all MPDs and reconnected
      • rate tests : no ethernet readout 100 % occupancy 1.7 kHZ, 800 Hz with ethernet readout, 1% to 2% 4.3 kHz with ethernet. Ben investigating why is a bit lower that expected
      • looking at common mode supression - few channels look fine with common mode suppression but look odd with zero suppression
    • INFN clean room
      • trying to get at least one layer going, so can test shielding, running fine with minor cable connection issues
      • SSP readout on hold for now, maybe after BB is installed in the Hall - might want to set it up early for development while installing in Hall A
    • UVA clean room
      • tested with Bogdan with aluminium shielding, see same noise reduction as copper, will go ahead with alumimium shielding
      • after remove 3 layers to GEN RP , now space for UV chambers
      • reiceived cable ferrites, will test next week
    • VTP setup TEDF
      • about done port MPD library to VTP, debugging fiber links
      • might want to setup SSP optical setup in UVA clean room
    • CDet
      • still odd issue with ADC - Alexandre will look at it next week
