  •  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)



  •  Lucretia model server conversion
    •  python PVA service
    •  matlab interface class
    •  GUI conversion

  • 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

  • 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 high-priority GUI model uses. 
  • 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...

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
    • python PVA will make it straightforward to build a LEM CUD



  •  New Phase scan GUI
    •  L0 phase scan automation
Phase ScansBuschmannDONE2

rudimentary functionality, needs with-beam test

  •  Add quad scan emittance measurement function (for L0)
Optics MatchingPerez3last step needed to migrate off of the LCLS-side emittance application. seems to be already partially implemented, so the challenge here is partially archeological in nature.

  •  RTBSA for FACET-II
    •  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

  •  Full lists of PVs used in HLAs accessible from each help menu
GlobalPerezWIP3F2_Feedbacks does this already with a hardcoded list, something similar could be done in other GUIs than have a lot of anonymous matlab PVs – ideally this could be automated by parsing the GUIs internal list of PVs
  •  Add Logbook feature to BSA GUI

Wire/Multi-WireBuschmann (+intrepid sidekick?)Done1

Both wire GUIs use the F2_WirescanApp object – save fit data/timestamps etc there, then GUIs can log & display that info as needed

  • update 3/5/2024: got the skew/kurt calculation implemented and have GUI frontends updated in-kind. still need to do some correctness checks and add timestamps
  •  Implement real-time rms energy spread PV with SYAG stats
Buschmann/ParkerWIP2Camera is serving stats. Just need a way to measure a conversion factor of MeV/pixel, then write both the calibration and the sigmaE to matlab PVC
  •  update 2/28/24: need to better understand what AD plugin stats actually calculate, the quantity I thought was the Xrms is not
  • simpler solution: measure the MeV/mm calibration and make an MeV axis so the sigE can be eyeballed
  •  Create tool to display corrector strength relative to beam energy vs Z.

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
