| General safety updates |
| - Be careful of sharp cable ties
- Someone got stabbed by one
- Try to cut cable ties so they aren't sharp
- 750 pit fire
- We are storing HE CMs down there
- Power still out
- Be aware of burning smells
- Smell something say something
- Be aware of egress paths in your work area
|
| ops call tracker |
| - Remember to update the ops call tracker
|
| Information PV |
| - New PV setup to keep notes on cavities that don't behave quite as expected
- Example: HL1-7 keeps failing SSA cal. How to communicate to ops
- Sebastian is figuring out how to add text
- Lisa is figuring out where to put it in Auto setup
- Sebastian: Needs to be obvious that they need to look at it
- Lisa is thinking about a button beside the EDM expert panel button
- Lisa: it's harder than you'd think to have the button light up
- Release soon with no light up?
- Ops checks if something goes wrong
- Take longer to develop highlight
- Sonya: add indicator beside the button?
- Sebastian: hover text over the indicator?
- Might disappear to quickly to be read?
- Sonya can add another PV to track severity if that is useful
|
| PAMM Work AMRF |
| - Shop getting some chassis ready for the next PAMM
- They are going to try to replace some chassis for troublesome cavities
- Need to calibrate with new chassis
- This will help identify problem when we restart
- Sebastian: should we ask for more restart time to check out cavities with replaced chassis
- What cavities/chasis
- 17-4 (RFS2), 12-3 resonance chassis
|
| Fake Quenches |
| Had large chunks of the machine have fake quenches all at once - Whole machine one day
- L1B all crash (Saturday)
- Jing: PRL looked okay, MO looked okay
- Ryan: noticed CM01 was off and can see spike on PRL readout
- L0B + L1B fed from same source
- Sebastian: is there anything we should ask ops to look at or document when it happens
- Sonya: it's too fast... nothing for them to catch
- Added some new monitors that will not get cross-talk signal
- LLRF MASTER SOURCE PRL Diag, LLRF PRL Diag Other (RF Global)
- Forward not connected for some of them
- LO power only read every 10 seconds
- Jing: always look at S2 MO power, RACK PRL STD
- Could something in cryo be related?
- Sebastian: we could turn off the quench resetter to get more information on cavity quenches
- Some we might not notice due to the instant reset
- Linac locking work ongoing. That might be having some impact.
