Agenda

Analyzer code updates

1. Recent branch activity & pull requests
   • Have merged several of the pull requests in
   • One which is pending is to remoive the outdated "qwparity_simple" executable
2. burpcuts
   • this is not quite the same as the stability cuts. I have a framework idea in progress, may be ready to hand off to someone later today or tomorrow
3. miniruns & regression analysis
   • Several issues have been opened relating to getting the minirun functionality. It will be based on the burst analysis.
   • RR is working on getting the corrected detector values, and will put into github soon
   • Sent an example of the current correlator output to Sakib to include in aggregator.
4. feedback
   • Want to add HC calcuation of means and widths to the feedback engine to send to EPICS for OPS to look for correlations with machine configuration
   • Total "lag" from feedback has been looked at briefly and seems to be a few seconds
5. Beam modulation
   • Updates to the bmwClient
     • Plan to test changes tomorrow (May 30) sometime
   • Decoding and BMOD tree extraction
     • RR was working on the BMOD tree extraction, but was pulled off to work on the miniruns and greenmonster. He'll push a work-in-progress branch with what he had so we can hand off to someone else

Hardware/DAQ tasklist

1. EPICS run-start and fast logger (and EPICS decoder to slow tree)
2. Timing: mostly understood, still small mysteries (LNE)
3. Synchronization-check system. w/help from Ed Jastrzembski
4. Clean up cabling, labels, fasteners - First need to examine all signals
5. 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 and beamMod client.
6. Pedestal studies, aka cross-talk
7. Green Monster rework: Robert
8. automatic production of run-dependent database
9. alarms like end-of-run voice
   • later
10. e-logbook entries
    • later
11. Document everything. Circuit diagrams, cable map, "how to".
    • CC: will make circuit diagrams.
12. ADAQ and HDD system monitoring
13. Remote power supply cycling capability:
    • CC: asked Alex about this and he said there are some. Will investigate further.
