10 minOn call normsAll
  • Linac should not have been turned on at 3am
    • Lisa was called and spent 3 hrs helping turn on
    • Auto set up worked excepts SELA
    • Ryan suspects issue with ramp
  • Calling ACR back within 30-60 min is acceptable
10 minAuto setup
  • Add Janice's auto cheeto code to auto setup?
  • Sebastian said some cavities were on the edge of tripping from forward power
  • Sebastian suggests not running Janice's code in <>?
  • Ryan - cavity display was showing purple piezo faults, piezo feedback turns off and is not regulating
    • Dan - watch piezo voltage
    • Ryan - piezo control loop is invalid not detune
    • Dan/Lisa - do two steps, run autotune, use SELA then chirp
    • Two use cases, add flag to use chirp
  • Dan - all cavities need to be tuned at gradient?
2 minPower outages
  • Lauren/Janice - Magnets getting turned off, vacuum valves in, WS turned off
  • 4p on Sunday, everyone will be at ACR for cold landing
  • Everyone take Monday off, Lauren will take Wed off
1 minConference
  • Posters need to go to Bambi by 19th 
  • Dan can take all the posters
30 minCavity display
  • Janice - more than AOT is going on when cavities quench/misbehave. 
    • how to differentiate between AOT and worse things
    • Sonya can add new alarm for PRLSTD?
    • freakouts are still happening time to time and we need to signal operators
  • Dan - make PV for diff between Acct and Amean/Ades?
    • same as AOT? but make one when diff is larger than AOT threshold/a lot
    • some AOTs are microphonics but not big excursions
  • Sebastian - flag on frequency deviations, that should never happen
  • Janice - votes for checking Pzt:DF_RFS>50/100 & AACTMEAN.SEVR=MALOR
    • New fault, JIT? jitter higher in warning hiearchy 
    • Sebastian, worried AACTMEAN.SEVR would happen too often, but ok w/ the first half?
    • Sonya working on this ^
    • Can help future freakouts get catered?
    • Sebastian, maybe PZO flag is enough? greater than 100 Hz should never happen?
  • Lisa. - why not DFBEST?
    • Sebastian/Janice, not the right PV to look at?
    • She can add severity check in cavity display for detune
  • Janice wants operators to be able to cater bad PRL's




Action items

  • Lisa requested archive of failed ramp up/SELA issue
  • Lisa M Zacarias update autotune to have chirp flag and ramp issue
  • Send conference posters to Bambi by June 19th, 2023
  • Lisa M Zacarias Ask Sonya to add if PZT:DF_RFS>50 Hz, flag red and
    • PZT:DFVALID_RFS is not flagging when appropriate, change threshold/lower 
    • Can we get red status for DFBEST > 50?
  • Lisa M Zacarias will add DFBEST to cavity display (warning and alarm as DET or JIT)
