Waiting on model server deployment

  • 3/13/24: current plan is to deploy a second PVA server that writes LEM EREF/EACT/BDES etc to an NTTTable, then the ModelReceiver can be updated in-kind to provide those quantities

  •  Lucretia Bmad model server conversion
    •  python PVA service
    •  matlab interface class GUI conversion?
GlobalCesar, Perez, BuschmannS2E group + Buschmann + moreWIP1

Lattice files for Brad already exist. Current high-level goals are:

  • Establish agreement with Lucretia (S2E et al)
  • Implement interface to live machine parameters (Buschmann)
  • Add Bmad model to python PVA server
  • (TBD) Convert GUIs
    • Depends on tao→matlab compatibility
    • alternative: PyTao would let us rejoin the LCLS shared application ecosystem in some areas (emittance GUI, wires)

  • 1/12/24: demo PVA server works, writing live/design Rs and twiss params, but matlab pvaGet not working yet. next step: document lucretia dependencies across matlabTNG to determine what the matlab interface needs to do
  • 1/23/24: matlab PVA access works with a python workaround (good enough for now, likely need a better long-term solution) Cesar prepped draft interface design document. reviewed

  • 2/8/24: PVA server is running but not deployed to prod yet. Drafting implementation of matlab class F2_ModelReceiver - once the lucretia functions GetRmats, RmatAtoB and GetTwiss are replicated we can proceed to test GUIs. Need to check w/ controls deputes to get some watcher PVs set up
  • 3/12/24: draft version of receiver on GitHub, testing for correctness and use by GUI controllers
  • 4/9/24: F2_ModelReceiver 0.1 version is ready for deployment, unfortunately the python models service has some errors in it, but the mechanics of the interface are mostly stable
    • 4/18/24: live model is currently starting from the gun, which produces very unrealistic twiss parameters. Need to start sim downstream at some treaty point
  • live model GUI gets marginally more realistic outputs starting from L0BFBEG, one option...
    • more realistic: take the latest PR10571 emittance measurement, back propagate to initial twiss at L0AFBEG – there are some kind of hooks in place for this already. but I'm not 100% on if they ever worked.

    •  python class for streaming BSA data
    •  python class for real-time BSA time series & correlation plots
    •  GUI
BSABuschmannWIP2
  • 07/05/2024: Developed proof-of-concept GUI using lcls BSA PVs - works for us as well since our BSA encodes pulse IDs the same way. Corr plot with fitting, time series and FFT are all working.
    • still need to optimize syncing for network performance
    • likely can replace the current RTBSA GUI for lcls as well

  •  New Phase scan GUI
    •  L0 phase scan automation

rudimentary functionality, needs with-beam test

    Standby Tasks / Wishlist / Brainstorm

    ...

    • Remove remaining dependencies on legacy Matlab2012 & "matlab model" code
    • Remove instances of direct use of LabCA - move everything over to using PV class in readiness for implementation of PVA
    • Beam stay clear plot vs Z (beam aperture vs Z, or acceptance vs delta E)
    • Automation/tools to facilitate 7-hole alignment 
    • Injector RF waveform generator tool
    • MPS interlocking for EOS
    • Klystron jitter report 

    LEM

    • write L1-L3 design phases to PVs
    • ignore CQs/SQs when propagating twins parameters. (BMAG plot)
    • flag "matching quads" and handle separately when "Lem to model"
    • fix BACT=0 causing NaNs in BMAG propagation

    ...

    • indicate TRIM operation in progress by disabling UI
    • Orbit fitting tools
    • Allow reference orbits to have names changed in Python Orbit Display Reference Orbit list

    Optics

    • wire names don't update in multiwire matching tabs after changing linac selection
    • automatically de-select CQ/SQs from matching options
    • native quad scans → ultimate goal of fully migrating off of the LCLS emittance GUI
