Task Lists and Schedules

The Feedback Prototyping project includes several sub-projects. A task list and schedule is (will be...) included for each:

...

  • soft IOC simulator to generate data for feedback testing
    • add simulation of user controls for LLRF
    • add calc of real BPM x-position values, replace virtual energy device for Energy feedbacks
    • add calc of real BL11 reading, replace virtual current device for Energy / Bunch length feedback
    • as ICDs become available add limits, resolutions, EGU etc  to simulator
  • Individual Feedbacks
    • Bunch Charge
      • gotta get going on this soon!
      • need ICD for toroid
      • need ICD and additional info on inner laser energy loop
    • Energy at DL1 / Spectrometer Dump
      • LLRF questions - need ICD (including PV names and how they work)
      • add control records on LLRF Amp and Phase to lock out users during automated feedback
      • need BPM ICD
      • need dispersion values for each BPM - they are not in SLC Database, store in config file? Need that oracle database here...
    • DL1 Energy + BC1 Energy + Bunch Length
      •  need to use IM01 to calc Bunch Length values (along with BL11 reading)
      • where to get calibration constant C for BL11/ IM01 calcs? See doc  from Paul
      • need ICDs for toroids and BLEN
    • Injector Launch
      • test Paul's latest optimization algorithm with latest simulator BPM values and noise levels
      • need BPM ICD
