• Updates
  • HCal
    • New FADC working, taking cosmics
    • F1 switch to external clock in top crate with help of Mark and Bryan
    • Got cables from Mindy, will be installed
    • VME DAQ almost complete, needed a few additionnal parts

( next week or week after )

• • • will install discriminator with remote threshold
    • one channel need one lemo replaced
    • plan for moving HCAL racks May 10th, racks can be moved individually - decabling
    • DAQ location : one month down to get power and other utilities
    • will try to get computer and racks up
  • BB Shower
    • Trigger monitor and FADC fully cabled
    • Mark looking into readout
    • will take data until Jessee gives heads up for move ( 1 week before move ) , will uncable and detector and move in hall
    • will start setting up cable on trays
    • Jack did measurement of BB weldment, will check if it can get inside bunker
    • looking at individual channels for noise level, still issue of noise on one side after HV switch. Looked on scope and could not see difference left and right.
    • F1 trigger from TI : but F1 seems to not get it from trigger ( Data not ready error ) - going to NIM/ECL translator - pretty big delay ( ~ 700 ns for FADC and 1200 ns for TDC) - using TDC output - can use the prompt output OT#2 instead -
  • BB Hodo
    • taking data multiple run every day
    • gain matching on going
    • will add time threshold studies
  • GRINCH
    • took good cosmics run with large paddle
    • checked VETROC decoding was working, will test with ADC
    • Gasket material received and will be cut next week
    • scintillator paddle moved back to original position
  • LHRS
    • Maria working on detector cabling
    • setting up VXS in room 1546 for helicity with Paul
    • Centos 7 upgrade with help of Ole : ready for SBS cpu now
    • restored FADC DAQ, issue with fastbus ( all 0 in data from time to time : known bug ) - FB arbitration time out
  • CDet
    • still taking cosmics data
    • sbs2 working fine
    • still need put VETROC in crate
  • GEM TEDF/INFN
    • INFN GEM in test lab working
    • INFN TEDF looking at modified MPD, made things worse, maybe due to only have half of chamber powered
    • VXS for VTP readout - need IP - need get APV backplane for starting testing
  • GEM UVA
    • finished assembly 4 GEM layers, replaced with all good backplanes ready to move in GEn RP inline
    • noise study : help with Bogdan, test to find noise, grounding scheme to be tried

• BB FADC has couple of empty channels

• Scott giving HCAL talk on Sunday g21 - instrumentation

and poster session Sunday afternoon 2PM
