Agenda

1. New branch "operations"
2. online plots
3. regression analysis
4. feedback
5. DAQ issues
6. VQWK adcs
7. Pull requests
8. DAQ tasklist
9. Other issues
   • Run type classification
   • What types of signals would we want to be able to set an alarm on (single defined variables, sums and differences of variables with scaling, arbitrary arithmetic functions of defined variables, ....)?

Bob's DAQ tasklist

 TO-DO list for Parity DAQ
   updated Jan 4, 2019

Cameron & Bob: 1, 2, 4, 5, 6, 11, 12, 13
Tao & Cameron: 8, 9
Bob: 3, 6, 10
Cip, Cameron, Tao: 13  
1 Doing - Timing: mostly understood, still small mysteries (LNE)
2 Doing - Synchronization-check system. w/help from Ed Jastrzembski
3 Done - File naming, reset run num, finalize configs (INJ, CH, ALL) 
4 Done - Fix scalers on spectrometer crates.
5 To Do - Clean up cabling, labels, fasteners - First need to examine all signals
6 Clean up CRL -- eliminate so-called "dirty trick"
7 Check the 7200 scaler setup at injector, find a spare 7200.
8 Doing - Pedestal studies, aka cross-talk.  
9 Done - Test JAPAN. Need cable map & labels. Possibly maintain "pan" ?
10 Green Monster maintenance.
11 Doing - Test spares.  Repair bad modules.
12 Doing - Document everything.  Circuit diagrams, cable map, "how to".
13 Online software, a bit undefined since software is changing.
    (a) automatic production of run-dependent database
    (b) alarms like end-of-run voice (Bob)
    (c) feedback
    (d) coil-pulsing aka modulation aka dithering (Victoria)
    (e) panguin (GUI showing real-time plots)
    (f) prompt analysis
    (g) e-logbook entries 
    (h) archiving EPICs data
Accomplished
 * Revive all crates.
 * Deploy all ADCs needed and test each channel.
 * Build various DAQ configs with subsets of the DAQ crates.
 * Timing diagram, check timing of external signals and readout.
 * ET system upgrade, test rate limits, ensure deadtime zero.
 * Implement Bank structure.
