Agenda

Analyzer code updates

1. Recent branch activity & pull requests
   • #127---Removed old qwparity_simple, updated test cases that used it.
   • #144---Hotfix disable temp rootfile
   • #128---Updating qwhelicity pattern to calcualte burst asyms eventwise instea…
   • #145---Feature: second moments, errors, number of samples for bursts
2. burpcuts
   • New code in PK's workdir should demonstrate burp functionality for subset of objects; needs to be tested. Extension should be straightforward if it works
3. miniruns & regression analysis
   • Miniruns are in progress, but likely not ready at start of run
   • Day-one regression will be done over the entire run and output in the "blueReg" files
4. feedback
   • Branch has been pushed to github
   • Many new EPICS variables are intended to be written on the update cycle of the charge feedback to give diagnostic info to OPS
   • How to ensure we catch run transitions? Explicit kill and restart, or can the engine catch the run transition?
5. Beam modulation
   • Updates to the bmwClient
     • Total rework to do the looping and EPICS calls from a Linux process and send data to VxWorks using cfSock
     • Interaction with CODA will remain the same. There are changes to the VxWorks library needed to support this new system
     • Are there halls which want a 'FFB paused' signal, and do have their cables?
   • Decoding and BMOD tree extraction
     • New decoder has been comitted; needs to have cuts defined.
     • Post-production extractor is in progress
     • Still intend to do the extraction from JAPAN as part of first pass. Likely not ready at start of run

Hardware/DAQ tasklist

1. EPICS run-start and fast logger (and EPICS decoder to slow tree)
   • Is this ready to add to CODA on a permanent basis?
2. automatic production of run-dependent database
3. e-logbook entries
4. Green Monster rework: Robert
5. Timing: mostly understood, still small mysteries (LNE)
   • All crates now have timing defined at boot, scaler gates are defined as (HAPTB Gmn2 && T_stable)
   • 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:
    • CC: trying to figure out how to use them (talked with Jack).

ReSpin of APEX runs
