  • Updates
    • HCal
      • analog sum setup using for cosmics
      • DAQ running, can see pulses in data
      • still take a day or so to check out everything
      • can take cosmics to have things set up as in Test Lab
      • software setup
    • Bigbite Shower
      • finished all cabling signal and HV and trigger monitoring, cosmics paddle cabling and labeling
      • scalers : all supplies to make the special cables, need to make sure not to forget remove terminator on scaler
      • can see signal from the cosmics trigger - cosmics
      • mapping check on detector side
      • moving from front end to bunker for mapping check - only one mistake found so far
      • continue checks and turn one layer at a time and look at individual signals
      • HV can be controlled with HV GUI
      • cosmics calibration
      • Mark set up cosmics trigger, if someone need to use it coordinate with Mark
      • cables on table - used to look at trigger rates
      • odd thing with scaler rates : sum much higher than individual sum of channels
      • Provokar will check offset of the analog fan - to see where the threshold can be set
      • Cable for threshold for DAQ - still need to be installed - 50 meters might be long enough for that
    • Bigbite Hodoscope
      • HV just setup thanks to Steve
      • LV : were thinking combined voltage with GRINCH but did not work out to have both for GRINCH and hodoscope, so need another supply, Jack ordered another supply
      • cabling : need extension on TDC cables - next week
      • can start looking at signals straight from PMTs
      • all cables laid out
    • GRINCH
      • good progress
      • GRINCH fully cables
      • HV cables and on
      • checking all signals, 3 BNC head need to be fixed for ADC, most signals look good
      • powered HV incrementally : most TDC channels are working
      • need to replace 2 NINO cards
      • some boards cannot reach 5V
      • hodoscope using older version
      • can use spares - old version found by Rachel - she is shipping it
      • checking mapping of detector
      • scalers display working in the bunker in bbhodo account
      • still need to try to run CODA
    • LHRS
      • Maria working on the PID software
      • looking at target reconstruction
      • Bob still working with Ole on counting house
    • CDet
      • last of optimized resistor in
      • few individual pixels which have smaller than expected amplitude - might need to fix / adjust
      • once all fixed will take cosmics for threshold and efficiencies
    • RF time
    • HV
      • All HV crates are up, except for VME CAEN card in INFN GEM
      • EPICS for HV working
      • if want to try : go to aslow@adaqsc and type gohv
      • GUI for HVs
      • will give infor about HRS to add to the EPICS GUI
    • Scalers
      • progress with scaler
      • scaler server setup - Mark is using to look at rates
      • 4 G0 scalers are working - could use for detector rates - need to make sure width is greater than 20 ns - can be used for monitoring
      • trigger monitor just for rates - will use to monitor trigger rate - check discriminator width
    • EPICS
      • David on site
    • Helicity
      • Paul on site this week , helicity signal patched down to LHRS , and patched down from patch panel to behind the wall, can use to go to SBS crate
      • disconnected the RHRS cables so we can to patch to go to SBS DAQ
      • need 12 cables from DAQ bunker to behind green wall for signals
      • signals connected to helicity scalers : check with standalone program, everything is showing up, still need to integrate code into crl for LHRS
      • minor modifications need for the QWeak helicity class to get it to work with the current system - inside Podd framework - we are using the master version - 1.75 - Paul will add to master - will be used as a plug-in same as usual helicity decoder - might still need to recompile Podd after added
    • start / stop / EPICS scripts
    • GEM
      • Bigbite GEM Hall A
      • took pedestal data with SSP two days ago - UV UVA look as expected -
      • lot of noise compared to TEDF - 20 to 100 ADC in Hall - not sure source - might be grounding and other to be improved
      • trying to find if BigBite can be shielded to see if this improves noise
      • shielding on J3 in Test Lab, but still HV issues to be figured out
      • all fibers working on SSP
      • all UVA chamber to VTP : can get VTP data this morning. Some fibers not showing up. Holly swapped around fibers - but still need to figure out issue
      • INFN : just working on shielding - no DAQ for now
      • received fiber extension - can lay out spares - need to check if we have protective sleeve - most likely 100 feet left - check with Scott
      • UVA  : just testing Bigbite setup
      • might move from cleanroom to TEDF
  • On-going tasks
    • Network setup ( done ) - SBS MPD side might need few cables - need pull network for SBS side (0%) - MPD bunker will move with SBS - ordering longer fiber to take that into account
    • Scaler crate setup (90 % - Steve )- still need to add the CODA part - if add barebone read out - right now scalers at 3800 - helicity scaler set as 3801- could work if stay this way- Steve scan the crate - can make that the scaler is not initialized by Steve program - sbsvme29 - Steve could not talk to CPU - IP fixed with DHCP - need change fan tray (done )- CAEN
    • documentation of VME crate names to power cycle - [[1]]- 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
    • 2 bad FADCs Bigbite - 1 FADC was repaired - one being repaired - 1 Compton FADC - repaired can use as spare ( done )
    • 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
    • GEM HV IP need setup ( Alex ) Done
    • GEM clock/trigger box for BB side
