Hall C will stop taking beam 4pm Sunday.
Hall A will stop taking beam 8am Monday
Hall B will not be ready for beam until 4pm Tuesday.
Four shifts are therefore available for beam studies and maintenance.
I'd like to see four hours allocated to cavity restoration, including RF
repairs, lem, and cavity phasing to viewers. Monday or Tuesday Day.
We need to set up second pass beam to the B dumplet Tuesday day shift.
Mark Dalton has some things he'd like to do.
Joe Grames is working up a list.
I think it worthwhile to spend 30-60 minutes trying to get 80 uA CW, 93
kW, to the BSY dump while we have the time, but it's not pressing.
The CHL has been very stable since the hardware changes made July 7

so it may be OK to do the SL21 JT valve flow test. This is compatible
with injector work but not with RF recovery in power permit, much less
spinning up beam to to phase recovered cavities.
PD Mike Tiefenback will decide.
