Agenda

Analyzer code updates

1. Recent branch activity & pull requests
   • Burst analysis development: PRs are just about ready to merge; Wouter will check today
   • Burp cut: Ready to merge
2. Activating the blinder
   • All detector channels are currently marked as "not blindable". When we reconnect the quartz into the parity DAQ, we will need to change the status of those channels to be blindable.
   • Offline/prompt analysis seems to be properly determining the blinder status from EPICS events
   • Online analyzer doesn't get the EPICS data properly. May either use EPICS calls directly, or an independent run-dependent blinder for the online displays
3. miniruns & regression analysis
   • The minirun correlation analysis is ready in the feature branches; should merge to develop soon
   • Wouter will add a branch which has regression enabled on the VQWK subblocks in addition to the hw_sum..This may stay on the independent branch instead of going tinto main use...
4. feedback
   • Amali had been starting to look at adding the new variables; having trouble accessing the variables. Rakitha will assist
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 done
     • 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.

Prompt analysis toolchain

1. • The engine is run twice, and then several scritps are run to produce plots
   • Plots got to a web directory
   • What tools are we missing for the WAC?
