Standby Tasks / Wishlist / Brainstorm
- Generic/Global
- 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
- laser heater GUI
- MPS interlocking for EOS
- Klystron jitter report → should get an automated FTP update script process thing
- laser cathode auto-alignment software → meeting w/ LCLS injector AP to discuss methodology
LEM
- 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
*Orbit
- 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
Feedbacks
Feedbacks
- tie DL10 set point directly to LLRF control (switch off "slow FBtie DL10 set point directly to LLRF control (switch off "slow FB" on RF controller when FB on and vice-versa, increase gain)
- Implement full PID controller coefficients to each feedback, setup and test and include P or PID as option (at least for DL10)
- Implement use of LI17 fast phase shifters for BC20 feedback through SCP multiknob controls
- Auto-adjust gains for changes in beam rate
- Add FFS transverse feedback
MDL Feedforward
Wirescans
- Wire scanner GUI not set wire speed to such a low speed after a scan that the following scan fails if you change planes for IPWS1.

MDL FeedforwardPreferred development workflow with git repository:- Create new development branch for work in personal clone of repo
- Do work and test
- Merge in any recent changes from main branch
- Push your branch, email Glen to evaluate & merge into main branch
