  • Updates
    • HCal
      • Cables from FE to bunker : about 20% done ~ 2weeks to complete - could use man power to unroll cable while 2 people installing
      • 5 to 9 Sebastian and Provokar out of town
      • power to HCAL racks - still no power - issue with transformer - Jack thinks transformer might not have enough power
    • Bigbite Shower
      • starting laying cable
      • HV cables were found to be to short ( 25 m - need 30 m) - 10 m extension found - making more extensions - signals cables not laid out
      • HV location changed
      • BB shower VXS
    • Bigbite Hodoscope
      • working in Hall staging cables : ADC cables in bunker ready to be plug when BB cable tray is installed, waiting for cable tray for detector to bunker
      • Rachel and David working on SBS-Offline software
    • GRINCH
      • Fully cabled : ADC and TDC at both ends, some slack left in middle way, can adjust if needed
      • ADC cables on detector
      • just need HV to take data
      • LV cable needs to be extended for NINO supply
      • some cables connectors need to be repaired
      • will setup GRINCH CODA on counting house computer
      • repeater rack is in bunker - 100 m TDC cables
    • LHRS
      • Maria plots of A1
      • VDC maybe one bad card : Jack knows about it
      • Scaler server from Steve setup for both crates
      • Scaler ordered postponed to Oct 1
    • CDet
      • taking data, fixing problems
      • identified replacement PMTs
      • HV still running
    • GEM BB Hall A
      • fibers setup
      • LV ready
      • can power up on Monday
      • Bryan get closer to completion, Ben showed ROC part working for FADC
      • ready next week for VTP in Hall A if needed
    • GEM INFN Test Lab
      • Test SSP readout
    • GEM UVA
      • working on shielding
    • Beamline
      • software, monitoring scripts almost setup, writing shifter documentation
      • looking at PREX alarm handler
    • Helicity
      • Bob and Paul, will go in LHRS to install scalers - One scaler has a bad user bit 2 and on has a broken NIM input - could use ECL - ECL scaler - could use one scaler from scaler crate at entrance of hall
      • work on analysis software TQWeak class compatible and should be
    • HV
    • Scalers
      • 2eVME
      • Crate to be installed under hodoscope
  • VME controllers
    • Bryan helping set up, most should be up in a few days


  • On-going tasks
    • Network setup ( done )
    • Scaler crate setup (75 % - need put crate in / setup cpu )
    • 3 rd GEM VXS crate install router moved up ( 75% )
    • need power and network in GEM bunker
    • detector accounts setup ( check with Ole )
    • boot VME controllers (GRINCH Hodo Shower , 2GEM crate up ~60 % controller booted - Bryan setting up as in TEDF - need setup MPD new controllers)
    • detector cabling -
    • new MPD production - about to start - need to ship our FPGA to Paolo
    • MPD VTP readout - on-going in daq lab - being setup in Hall A - need setup VTPs to boot
    • setup portservers
    • need to install remote switch for crate in bunker - rest are VXS or VME64
    • Bigbite - HCal trigger setup
    • TS setup - 0%
    • Beamline crate setup ( in scaler crate )
    • HCAL cabling
    • HCAL need power
    • Mark hodoscope trigger ?
    • Computer move to Hall A : sbsdaq1/2 tedbbdaq enpcamsonne
    • LHRS fiber pull


  • Outstanding issues
    • 2 bad FADCs Bigbite - 1 FADC was repaired - one being repaired - 1 Compton FADC
    • SD delay : still need 2 SDs ( Glasgow and INFN just requested quote )
    • need to adjust for HCAL transit time with different PMTs
    • status of cosmics paddles ( installed by Bogdan )
    • GEM fibers too short : 60 m ordered
    • 15 bad MPDs
