| Time | Item | Who | Notes |
|---|
| Ops communication highlights | All | - Make sure to clarify to ops when they should pass information on to different shifts to avoid unnecessary calls
- Ask them to make logbook entries
- Common problems communication: AOSD 3 pm Thurs meeting? Confluence?
- Discussed having ops regularly check for red boxes
- Get ops in the habit of checking out the SSA expert panels just informationally?
- Might be confusing due to HL ganging issues/generally scary
|
| Recent cavity measurements |
| - Different manufacturers have different cavities with different flux expulsions due to Nb supplier differences
- Have a problem resolving Q's above 4e10 - 2W of power resolution is very challenging
- How much can we resolve different heater powers?
- Probably can't trust a calibration more than 24 hrs old
|
| Schedule |
| - Nicole and Ryan to run up cavities together tomorrow
- Nicole will take notes on the flow charts during run up
- Will need to come in on swing shift 6/11 (Sunday) to do cavity detunes before June downtime
- Email Dan if there's a time we can't be on-call in the next few weeks
|
| SSA's/CoHE/Fans? |
| - Request: drain voltage setup to nominal isn't automatic. Can it be?
- Andy: should be something Mike Dunning can take care of
- 'Fan ritual' for HLs is a pain
- Don't have even have SW from R&K to deal with it at the moment
- 10-6 SSA tripping off frequently - SSP error
- CoHE problem, will be dealt with eventually (CATERed)
- Andy would like help looking at cavity scale parameters alarm for <25 MV (or was it 20?) and >50 MV
- Some are quite low, need an attenuator
|
| Misc Updates |
| - Fudge factor - separate meeting
- Decarads to be moved in June downtime
- Briant has a job to look at the magnets in CM22
- An Le is working on STDZ and degauss errors today
- Rolling out phase offset drift test to CM32
- Detune frequency drift test will take longer to roll out - no software fix yet
