• Updates
  • HCAL
    • cable GUI installed on enpcamsonne, section 7.5 on wiki for documentation
    • looking at cable length attenuation

globally

• • • gathering spool of cables and lemos to give to Wendy for 60 more cables for overlapping summing
    • Chris agreed to make a patch panel for the DAC
    • looking for the FADC being repaired
    • maybe look into setting up external clock for F1
  • Bigbite shower
    • Issue with Fastbus getting stuck in weird state. Bryan has a temporary fix.
    • 12 FADCs added, jumpers checked to be set to 2V and will start cabling
    • Provokar more data for preshower calibration and will switch to FADC
    • noise on one side of preshower, HV crate was replaced ( goes away when moving to other HV crate ) but still shifting pedestals on some channels, still need to look at signals with scope ( usually 5 mins runs ), might be ground loop - HV supposed to have same ground but need to check. Some channels have the shift on some channels with scope directly on PMT ( grounding near PMT did not help ), but disappear R26 when HV swapped to another HV card.

Schematics of bases of PMTs ? From Hermes not sure we have. Look with scope on HV too, see in Fastbus even with filter ( so higher frequency noise ).

• • Bigbite hodoscope
    • fix issues with analysis script - everything working
    • more data taking
    • Steve working on the TDC scaler using the hodoscope DAQ
  • GRINCH
    • still working on integration in SBS-offline , some work on best structure
    • software running but no data - need to check map
    • Juan Carlos has information for podd debugging to display data
    • already checked with datadecode that raw data is fine, so still need to fix decoding software
  • LHRS
    • problem with HV tripping on VDC, added more oil on bubbler fixed it
    • Maria working on the DAQ
    • eventually will port the FADC setup from Bigbite
  • CDet
    • issue with sbs2 computer but it was because UPS dead, now plugged directly so working now
    • taking data , students looking at data
    • Ralph set up CDet channel on slack
  • TEDF GEM
    • slides from
    • clock : daisy chaining from input to output - going through PLL and delay - Ben prefer star configuration to daisy chaining - input 50 ohm terminated low level TTL
    • just run on internal clock for the phase study
  • UVA GEM
    • APV front end and backplane being repaired by electronics group
    • tracking APV baseline issue - might be from 5 slot backplane - will try next week
  • TS crate cabled, need to switch to CODA3 Centos 7 and continue next week
