Agenda

Analyzer code updates

1. Recent branch activity & pull requests
   • Burst analysis development: several pulls should be ready to merge, but my comparison to previous versions is not yet working because the print-runningsum doesn't work due to the runningsum changes. Rakitha will look at it.
   • Burp cut: Robert has pushed a set of changes that seems to work, and a quick comparison with previous results shows agreement. May need a little further refinement.
2. Activating the blinder
   • Online analyzer doesn't get the EPICS data properly. May b=either use EPICS calls directly, or an independent run-dependent blinder for the online displays
3. miniruns & regression analysis
   • The burst developments
4. feedback
   • Amali had been starting to look at adding the new variables; Rakitha can help
5. Beam modulation
   • Updates to the bmwClient
     • Client is basically working now, may need some tuning
   • Decoding and BMOD tree extraction
     • New decoder is in operations. May need to recheck channel map
     • Post-production extractor is in progress
     • Still intend to do the extraction from JAPAN as part of first pass.

Hardware/DAQ tasklist

1. EPICS run-start and fast logger (and EPICS decoder to slow tree)
2. automatic production of run-dependent database
   • Up and running, Home page: https://hallaweb.jlab.org/rcdb
   • WAC comment gui, and WAC DB edit tool
   • Just a couple more example scripts to add
3. e-logbook entries
   • All three are now active
4. Green Monster rework: Robert
   • An "official" copy is installed under ~apar/devices/PyGreenMonster. Later we should import it into the DAQ repo.
5. Timing: mostly understood, still small mysteries (LNE)
   • I think some CRLs still have module initialization at Prestart, so we need to pull that out.
6. Synchronization-check system. w/help from Ed Jastrzembski
   • Scaler-based sync for injector is better, but still not 100%; see [1] and attachment
   • New digital system will be available some time after the run starts
7. Pedestal studies, aka cross-talk
8. alarms like end-of-run voice
   • Data quality alarm concept: a realtime engine will report problems via text output on a periodic basis (~few seconds), the alarm display will poll this and warn the shift crew.
   • "End-of-run" voice would be tied to coda transitions
9. Clean up cabling, labels, fasteners - First need to examine all signals
   • CC: working on it.
10. Document everything. Circuit diagrams, cable map, "how to".
    • CC: will make circuit diagrams.
11. Remote power supply cycling capability:
    • Most things we need on them are now on them. The spectromater parity crates are not, due to power rating of the remote strips.
