See slide. Mystery ground fault @ MI-60. MI-52 area vacuum leak. F2 manhole Grindex pump turned on with high water alarm.
Linac
Quiet. Good weekend.
Booster
Good weekend. Thanks to ops for tuning.
Booster Neutrino
Will need to change DI bottles tomorrow (5/2/17)
BNB Experiments
Running well.
Main Injector & Recycler
Hopefully a simple vacuum leak. MI-60 North ground fault concerns due to logistics of the penatration (45 degree angle). Guessing that heavy rain caused temporary fault then dried up. Two possible options: 1) push cover up from bottom to surround PVC sleeve. 2) figure out how to pull inclined pipe out. Need to work with MSD for a plan. Hipot data suggest that there is a soft fault there now. Will inspect location today during MI-52 vacuum repair.
NuMI
Quiet weekend. Issue with adsorber rad monitor.
NuMI Experiments
Experiments running well. MINOS magnet tripped twice over the weekend. Trips related to rainfall. Investigating options.
Muon Rings
Power supply testing. Will take beam when available.
SY120
Ops installed protable sump pump in F2 manhole. Thanks to ops under the adverse conditions. F4 pond pump only runs in the 'slow' mode. Investigating.
SY120 Experiments
ODH alarm---- fire dept. did not find anything. Cryo controls suggested not a real Argon release, only a controls problem. Investigation in progress. Two experiments to be installed on Wednesday, M03 & MC6 21b. Not loosing any experiments.
ES&H
Will provide support for MI-60 investigation.
EE Support
Nothing to add.
Mechanical
MI-52 vacuum investigation. Rain water in that area.
Fluids
Make up Tev LCW today.
RF
MI & Booster running well. Recycler switched from cavity #1 to #2. Running stations #2 & #3
MTA
Accessing enclosure today for inspection tomorrow.
Controls
Nothing to report.
Instrumentation
Nothing to report.
FESS
Alot of sitewide flooding. Nothing affecting operations. F2 manhole pumps running but way below amp rating. (no load, plugged line) This week CUB strainers cycle time has gotten worse. Working on backwash option. MI-40 kicker room HVAC.
Miscellaneous
Linac Laser Notcher --- Working on spare, being aligned today. Future access to install ~ 4 hrs opertunistic access.
