    • taking data but timing needs to be done to look at detector signals
    • Eric should look at existing PODD classes for shower to decode Fastbus
    • Shower trigger  : less than 200 ns
    • test trigger lines : 190 ns might


  • HCAL DAQ status ( Scott )
    • 2 crates : 1 VXS crates with FADC and 1 VME64X with F1 and FADC
- see cosmics in both crates in FADC , missing in TDC ( need to check new timing with 2 crates )
- resolution lock issue with F1, might be overheating
- add blanks to improve cooling
- reduce resolution of F1 to see if problem goes away
- latency from TI ( OT2 is prompt output less delay down to 200 ns)


  • UVA GEM status (Bryan / Kondo )
- 3 VME crates in clean room with TI ( 2 VME and 1 VXS ) : 2 planes per crate , 1 TI and one fiber, need 1 TI with two transceiver
- using CODA3
- wiki with information on wiki : SBS_DAQ:_GEM_EEL_Cleanroom_setup

  • SSP readout ( Ben )
- 16 MPD for 1 SSP to be tested
- all transceiver and fibers on site
- test radiation hardness of transceivers and fibers


  • BCM digital :
- daughter board design done, need to make prototypes and test


  • Certification of electronics : need to check with Ed Folts ( Nilanga question )


  • CDet
    • All TDC for coordinate in weldment : need checks ?
    • Software : running DAQ CODA and root scripts to analyze, need to check if other functionalities needed. Library can be loaded in Hall A / SBS analyzer
    • amount of TDCs for CDet sufficient
    • 25 TDCs - need to check with Bob
