Agenda

1. respin of APEX runs: runlist
   • What output do we have?
     • CC will begin on the 30 uA runs
   • Agregator
     • Sakib had run the aggregator for the uncorrected trees. He also has regressed values in the aggregator tree.
     • Sakib says that for adding the values from the "mulc*" trees, we would need to have the "mul" and "mulc*" friended together.
   • Pair tree plots?
   • Do we have a "process a run" analysis chain ready? Do we want to set it up as a script? >> This will develop into the prompt analysis script.
2. "Operations" branch
   • Uncommitted changes
     • Parity/prminput/#prexCH_beamline_eventcuts.1356-1423.map#
     • Parity/prminput/prexCH_beamline.1572-.map
     • Parity/prminput/prexCH_beamline.Carynfix.map
     • Parity/prminput/prexCH_helicity.1588-.map
     • Parity/prminput/prexCH_helicity.1593-1595.map
     • Parity/prminput/prexCH_scaler.1588-.map
     • Parity/prminput/prex_sam_pedestal.1635-.map
     • Parity/prminput/prex_scaler.1588-.map
     • Parity/prminput/prexinj_beamline.1572-.map
3. Recent branch activity & pull requests
   • feature-cavityBPM
   • feature-PromptSummary
     • Sakib is still working on the formatting and adding in the new combinations. He expects that to be done in a few days.
   • bugfix-AggrigatorStringHandling
     • Probably ready submit a pull request. But Cameron had started implementing a new regression functionality into that branch. He will split it out, and revert the bugfix branch, test it, and submit a pull request.
4. regression analysis
   • Comparison between postpan and japan-correlator
     • Not yet reported upon
5. feedback
   • PK will follow up with Amali
6. Beam modulation
   • Updates to the bmwClient
     • Ye has made the changes to the client, but hasn't had a chance to test.
   • Decoding and BMOD tree extraction
7. VQWK adcs
   • One last module is ready to be tested
8. EPICS run-start and fast logger (and EPICS decoder to slow tree)
   • Updating EPICS decoder lists for PREX variables
9. Bob's DAQ tasklist
   • Timing: mostly understood, still small mysteries (LNE)
     • Current plan is to work on this early next week (Apr29)
   • Synchronization-check system. w/help from Ed Jastrzembski
   • Clean up cabling, labels, fasteners - First need to examine all signals
     • CH crate has a preliminary cleanup and Caryn is checking signals
   • Clean up CRL -- eliminate so-called "dirty trick"
     • ??
   • Check the 7200 scaler setup at injector, find a spare 7200.
     • Talked to Bob related to timing. Event counters
   • Pedestal studies, aka cross-talk
     • Tao will look into it soon.
   • Green Monster rework: Adam.
   • automatic production of run-dependent database
   • alarms like end-of-run voice
     • later
   • e-logbook entries
     • later
   • Document everything. Circuit diagrams, cable map, "how to".
10. Thinking about the tune mode scan
    • How long do we want to integrate? Beam pulse may be 360 us long, followed by a 4us pulse for tracking the linac pass.
    • Can we do all of the gate shifting with the VQWK gate delay, or de we need to use a timing board?
