February 4th 2021¶

• VMM
  • gigabit ethernet working, data generated and sent through interface, next step hook up VMM evaluation board as data source - need phase adjustement between VMM and FPGA board - next step use pulse generator to feed VMM and use trigger to trigger FPGA board - finally plug GEM to board and use cosmic ray setup - setting up GEM in test lab so can look with source -
  • scaling from 12 to 128 using same gigabit ethernet for now
  • prototype board should be close to ready be end of February
  • test board INDRA
    
    
    **need to look a GEM and connector mapping
    *MPD APV : progress on VTP code - still need to run simulation - need to add the TI to the simulation for ROC readout - will test bandwidth after simulation done
    **UMass test stand : working on cluster finding simulation in Vivado - received 10 gig adapter - will install this week
• ASOC : plugged to detector - can recorded pulses - setting detectors in test lab for cosmics trigger
  *SD board order : quote requested last week
  *VXS crates for SoLID preRD - will be move to room 126
  *Xinzhan got zero supression and common mode subtraction working - one bug fixed by Ben
  *some plots from APV : noise in APV maybe coming from trigger - don't see in VME readout - might need to adjust trigger - might put 20 us - CMS rejected trigger - MPD bug in buffered in VME ( counter not incrementing/decrementing if trigger hspprns during readout ) , fixed in optical readout
