COMMENT ON Master Oscillator System - Obsolete 70 MHz Chassis Removal
Hi Matt, we could do it then, or if you're ok with it, we could do it much sooner (this or next week).
We can do this sooner, because the MO signals in the NL and SL were turned off (and left off) to avoid damage/overstress during the SL and NL breaker PMs earlier this SAM (as no one will run RF until we bring the linacs up, and no one has complained).
While the MO's central source and hub is in the MCC (Bldg 85), the system is configured so that turning its distributed elements off in the surrounding service buildings poses no threat to the system as a whole.
Again, I will let you make the

puck movement
Moving pucks with the aim of putting a GaAs puck in the HV chamber for HV conditioning (now delayed or cancelled due to prep chamber long manipulator)
Pucks 10, 31 and 3 were moved from the suitcase to storage manipulator 1 (closest to HV chamber)
Pucks 34, 9 and 32 were moved from the prep chamber back into the suitcase. Two of these are bulk GaAs, one is a used broken SSL
The mirror puck was then removed from the HV chamber. Inserting it last week went ok, but then the bearings stopped working well.
