  • Updates
    • HCAL
      • will try to restart DAQ
      • around 1 months
      • VTP : readout list and configuration done, need to make a config with VTP readout
      • need
      • output from CAMAC have copy for VETROC
    • Shower
      • look into cosmics this week
      • cosmics run for hodoscope
    • hodoscope
      • Glasgow will come for the summer
      • RF going in left side TDC
    • GEM
      • move to Hall A end of next week
      • fibers routing to SBS bunker - will route with other Bigbite cable around pivot
    • Helicity
      • setting parity DAQ for charge feedback
      • SBS data streams - 3 streams will be put back together - seed calculated in crate and reported at every event - helicity bits are in FADCs
      • prompt helicity - maybe not have charge asymmetry if one stream lost
  • Beamline
    • circular raster installed : checking uniformity, amplitude modulation giving a spike right now
  • Update 3 stream readout : on going
    • will send run number to Ole
  • Tasks for GEn run
    • GEM
      • install fiber and network SBS
      • add 2 VTPs to readout
      • cable detector
    • He3 target
      • EPICS ?
    • Helicity : prompt helicity ? - summer only Hall B cares - most likely should be ok - will need to check for fall
    • HCAL
      • VTP readout FADC
      • VETROC copy TDC
      • HCAL FADC trigger
    • Shower
    • VTP readout
    • Shower trigger
    • Trigger
      • tested during GMn
      • ready to go
    • diagram timing - and check timing
    • DAQ crashing more often with more APV
      • if run starts and APV is failed during configuration - will be automatically disabled -

and email send to mailing

      • stand alone tools given to people for diagnosing issues - GEM related issue - connection on fiber transceiver - tools to diagnose quickly - FS transceiver have reliability issues - similar issue in Hall B - switch to Finisar - all hardware in EEL was debugged
  • DHCP update : will try to move to main server using Jnet
