• Detectors DAQ status
  • BigBite
  • HCal

• CODA3 testing (Bob) pdf

October 4th 2019

• Bigbite DAQ status ( Eric )
  • slide here pdf
  • 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

- computer ready soon

- 3rd (VXS) crate with SSP and MPDs

• 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
