August 13th 2021

• Updates
  • HCal
    • HCal fully cabled
    • starting reestablishing DAQ, can log to ROC
    • will work today on HV (rpi20 and 21)
    • and try to take data
    • summing trigger should be working, need to adjust for delays with different PMTs
  • Bigbite Shower
    • Eric, Provokar
    • need plug in 15 more bundles
    • need plug scalers ( NIM/ECL converter to scaler and F1 TDC)
    • set up cosmics
    • need cable for BigBite shower thresholds
    • will finish cabling this week, start turning on next week
    • check mapping
    • Bryan configuring all detectors today - think to finish today
  • Bigbite Hodoscope
    • all ADC and TDC cabled at detector frame and signal going to bunker, all cables reach in bunker - TDC cables a bit short to reach converter -
    • connecting ADC, TDC, HV and LV left
    • software progress by Rachel
    • ADC cables 100 m
    • need to setup gate for ADC
  • GRINCH
    • existing cabling was redone at Bogdan's request - slack near BB was moved in near main bunker
    • half fully cable
    • other
    • TDC will be redone
    • HV cables laid and are connected
    • rpi17 HV
    • share same LV cable
    • software ok, still need online monitoring
    • still need to move to a-onl account
    • scalers display ? Existing and will be installed
  • LHRS
    • Maria learning PID for LHRS software
    • Bob helping Ole in counting room ( should be ready in 2 weeks )
    • still connect to connect to TS - should receive the part fiber next week and can try
    • pulser to simulation coincidence
    • EDTM ? Need to look for it
  • CDet
    • taking data to optimize resistors
    • after look different HV for efficiency
    • helping in Hall for installation
    • CNU starting again next week
  • GEM BB Hall A
    • 23 MPDs in Hall
    • all up to date for firmware
    • can update firmware in test lab
    • 10:30 AM power outage, because UV layers, LV was plug on same socket and tripped. Nothing can be read out yet. Being investigated, Thir bringing spares
    • need trigger fan/out box for rest of MPDs

• • GEM INFN Test Lab
    • HV test on two SBS layers, HV tripping is due to shielding - putting shielding in pieces to see where it can short -
    • SSP crate to update firmware for MPDs

• • RF time

• • HV
    • MPOD HV GUI for the GEM people
    • HV for shower and GRINCH up
    • will check hcal

• • Scalers
    • Also I got the DSC modules to work as scalers and I am setting up a bunch of SIS scalers as 3800s. I also have 4 G0 scalers that we could use, but we should make sure that they have wide input signals (>10 ns) and that we don’t use them for anything critical like deadtime, efficiency, beam current etc.
    • Bigbite scalers to be added to this crate
  • Recoil polarimeter
    • hodoscope plugged
    • DAQ rack for experiment set up
    • starting using Hall A system to boot CPU

• • EPICS
    • David found alh not available ( used on old computer - hacweb7 ) will move to adaqsc -

• • Helicity
    • scalers installed, Paul back from vacation

routine pick -up scaler event for the helicity seed and will be inserted in data stream

• • • helicity signal in counting room - not reaching HRS -need to check cable and trace
    • same data stream in SBS scaler crate : need libraries on sbsvme29, library for 3801 - could be easier if in different crate - will check to put it in TS crate or hodo crate
    • reported helicity and T settle signal tagged in trigger

• • • taking the RHRS signal to SBS weldement

• • start / stop / EPICS script
    • Bob has templates working with CODA3

• On-going tasks
  • Network setup ( done ) - SBS MPD side might need few cables - need pull network for SBS side (0%)
  • Scaler crate setup (70 % - Steve ) - Steve could not talk to CPU - IP fixed with DHCP - need change fan tray - CAEN
  • documentation of VME crate names to power cycle - need to make sure all VXS are in dhcp -Bryan
  • 3 rd GEM VXS crate install router moved up ( 100% )
  • need power and network in GEM bunker ( done )
  • boot VME controllers (100 % done - need ask hostname TS crate )
  • TS cables - all fibers plugged - will post informations -hodoscope / grinch/ shower separate - can be combined at any time now everything plugged to TS
  • detector cabling
  • new MPD production - about to start - FPGA shipped to Paolo -
  • MPD VTP readout - on-going in daq lab - still having issue getting APV sending data to MPD - events going through high speed link
  • MPD being setup in Hall A - need setup VTPs to boot (done ) - 10 gigE network plugged (done) - will be able to test in Hall A - LV installed soon (done )
  • setup portservers : 1 4 port portserver for VTP (done), still need to set up a 8 port one and HCAL portserver
  • need to install remote switch for crate in bunker - rest are VXS or VME64 -
  • Bigbite - HCal trigger setup - need check with Bob if additionnal NIM crate need to be install
  • TS setup - 50 %
  • Beamline crate setup ( in scaler crate ) - FADC is in scaler need to be setup - need pull raster BPM BCM (0% will do it with David )
  • HCAL cabling
  • HCAL need power ( done, Berta )
  • Mark hodoscope trigger ?
  • Computer move to Hall A : sbsdaq1/2/3 tedbbdaq (done ) enpcamsonne ( done ) - need to install X server - Need ask Ole -
  • LHRS fiber pull ( waiting fiber August 13th ) - most likely LHRS at end of SBS run
  • Cosmics trigger ( Bogdan ? 0 %) -
  • Cosmics HCAL
  • Cosmics Shower
  • Cosmics Hodoscope
  • Test 10 gig link to DAQ to adaq1
  • EPICS script -
  • alarm handler (David)

• Outstanding issues

  • SD delay : still need 2 SDs ( Glasgow and INFN just requested quote )
  • need to adjust for HCAL transit time with different PMTs
  • status of cosmics paddles ( installed by Bogdan )
  • GEM fibers too short : Mark will order parts - need to check status of order
  • 15 bad MPDs - need to look at fixing - Ben ? Dustin loaning us 6 MPDs - need 85 total - 67 in hand - 1 MPD (301) VME address issue in some slot -
    • APV needed 1208 - 966 in hand working - Michael might lend 40 - ( check with Thir )
  • GEM fiber possibly bad - 2 broken - if long sleeve want to pull spare in separate conduit
