*Status

• GEM ( Ching _
  • All MPD and APVs are in ESB
  • need VTP and V1495 - CPU and TI
  • low voltage
  • 1 VXS crate + 1 VME crate for MPD
  • 2 QSF board in Hall C
  • got fibers from Hall C
  • backplanes and adapter : 5 slots - Florian has the one for his chamber - Need more 2 slots ideally - need to get adapter fro Stony Brook
  • most hardware - need to setup crate
  • EPAS can copy and paste Bill's EPAS
• Computer
  • CPU TI SD - using sbsecal4 - need add VTP - SSP for MAROC
  • VMM3 board start to setup in ESB - we should have 6 of them - and start testing
    **MRPC
  • 64 channels of SAMPIC
  • 8 channels AARDVARC and 8 channels ASOC
  • main readout of MRPC will be A/D and vfTDC
  • will borrow NINO chips from SBS for the readout
  • or NIM A/D
  • CDet software
  • EPAS
• Infrastructure
  • new switch arriving in January
  • one small dumb switch in the rack - pull one 196 cable from rack in HKS

• PMTs readout
  • scintillators
  • FADCs for PMT readout : Scintillator, Cerenkov

• VTP
  *ECal single trigger
  *Scintillator
  • Ecal+Cerenkov
  • Pion trigger - scintillator after calorimeter
  • need volounters to program VTP
  • analog trigger -
    EPAS
    copy from Bill
    *Hall C
• we need fibers for VTPs
• need to check data rates and data volumes
  High Voltage
  Lecroy for PMTs
  **MPGD : CAEN ? and SoLID Wiener
• MRPC : HV Wiener - need
• NPS crate in SHMS - Bill can find cards and help with slow control - have positive
• LAD Crate -
  **HKS
  • DC need more ribbon adapters for vfTDC
  • can look at data with trigger time
  • FADC v2 for ENGE
  • still need to test V3
  • finished test KDC1 and KDC2 ok
  • will test all ENGE hodoscope data with FADC
  • will test EDC
  • LVDS repeater ? - Bill shortened the cable length - 125 ft - 150 ft - 2 to 3 % signal loss - might only need for ENGE - 40 ribbon cables might need repeater
