Agenda

Analyzer code updates

  1. Recent branch activity & pull requests
    • PK: the prompt summary will be checked soon. It makes use of the data handlers and formats things nicely.
    • PK: LinReg typo will be merged
    • CC: panguin fixes add loading shared lib functionality
    • PK: we should bump up the minimum requirement for the root (6.08 was reported to be broken)
    • CC: for the online monitoring and feedback (pull req 89); pushed the size of the chunk close to the ET system limit. PK: will have to study to see the impact on the online analysis
  2. regression analysis
    • PK: RR and TY have started making comparison between postpan and japanReg; RR: there are some inconsistencies between postpan and japanReg wrt event numbering.
    • CG: should we throw events that only one subsystem has a DeviceErrorFlag? PK: there could be a mismatch between devices when calculating a correlation.
  3. feedback
    • PK: talked to Amali before lunch and she still is having some issues figuring out how to get the XC charge asymmetry. CG: will follow up with Brad S
    • PK: at least it was tested for PITA feedback and we should follow up on the rest. CG: position feedback also worked. Hall C feedback on the IA was not tested and neither were the helicity magnets; but Amali thinks it should be easy to implement.
  4. Beam modulation
    • Updates to the bmwClient
      • PK: Ye is working on the BMW client and she is doing a test Wed. Will communicate with them to see if they can test it out before the hardware check on Wed.
    • Decoding and BMOD tree extraction
      • PK: VO promised to push something up soon.

Hardware/DAQ tasklist

  1. VQWK adcs
    • CC: one last module is going to be repaired. There is no timeline for this.
  2. EPICS run-start and fast logger (and EPICS decoder to slow tree)
    • RR: slow tree is reading everything fine. The fastLogger works. PK: will follow up on the start scripts today
  3. Timing: mostly understood, still small mysteries (LNE)
    • PK: Cameron and I fixed the 7200 scalers in the injector and made the VQWK in the CH consistent with the injector setup. We need change the injector and CH to use a timing board to set the VQWK start — so we can do a test with tune mode beam.
    • KP: we ran with timing boards for PREX1.
  4. Synchronization-check system. w/help from Ed Jastrzembski
    • CC: pending. This checks the scalers between the different crates. Injector and CH match.
  5. Clean up cabling, labels, fasteners - First need to examine all signals
    • CC: in progress. Labeling will be done once timing system is fixed.
  6. Clean up CRL -- eliminate so-called "dirty trick"
    • CC: that is Bob’s court. PK: we should look at the CH and injector CRLs once we finish up with the timing.
  7. Check the 7200 scaler setup at injector, find a spare 7200.
    • CC: Checked. still need to find a 7200 spare. Bob will ask someone in hall B for a spare.
  8. Pedestal studies, aka cross-talk
    • CC: plugged in a batter in the CH and injector crates. Analysis to follow.
  9. Green Monster rework: Adam.
    • AZ: worked on Compton; CG: let’s talk at the end of the day today.
  10. automatic production of run-dependent database
    • SP: all scripts are ready. Brad S. is working with computing center for a world facing server.
  11. alarms like end-of-run voice
    • later
  12. e-logbook entries
    • later
  13. Document everything. Circuit diagrams, cable map, "how to".

ReSpin of APEX runs

runlist

    • What output do we have?
      • CC: ran respin and will have to investigate the results
      • CC: aggregator works.
    • standard plots
      • CG: we'll go over the default plots at the 5pm mtg.
  1. "Operations" branch
    • PK: there were some extra files created during the injector studies. Will update soon.
