• 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 (done) )
  • 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 - working some fibers missing compared to SSP -
  • 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 - hareboot32 ( done )
  • Bigbite - HCal trigger setup - need check with Bob if additionnal NIM crate need to be install - will add NIM crate - in middle rack
  • 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 ) - FADC in scaler crate - for BPM readout
  • HCAL cabling - done
  • HCAL need power ( done, Berta )
  • Mark hodoscope trigger ? - need to convert LVDS Or to ECL and bring to SBS bunker - if useful - can ask Armen or Arun for help with making cables
  • Computer move to Hall A : sbsdaq1/2/3 - (still need to install x server ) - tedbbdaq (done ) - enpcamsonne ( done ) - Need ask Ole -
  • LHRS fiber pull ( waiting fiber August 13th ) - need few cables for trigger and L1A - if need fast L1A - for cable - will check latency - latency might be worse with daisy chaining - might still need to pull a few cables - want at least L1A for scalers - plan to run on 1 of 12 cables Green and DAQ bunker - can run additionnal signals there at the same time
  • Cosmics trigger - Done for Bigbite side
  • Cosmics HCAL - Done using overlapping trigger - could use paddles later -
  • 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 ) - will borrow two from Hall B
  • need to adjust for HCAL transit time with different PMTs
  • status of cosmics paddles ( done )
  • GEM fibers too short : Mark will order parts - need to check status of order - follow up on lead time
  • 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 - Ben fixed several MPDs ( 2 or 3 MPDs to be repaired )
    • APV needed 1208 - 966 in hand working - Michael might lend 40 - ( check with Thir ) - need to ask to Dustin if can borrow
  • 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 - ok for BB - need to make sure we have enough for GEn RP -
  • would like to put helicity control signals to be recorded on trigger - either TS/TI input bits - 3 signals - need to setup with TI ( I think firmware was updated to work - and will try - if any channels available for FADC- can add those too - could add to BPM/Raster FADC available channels
