Quick Check on WHY - FSD Masking (Destination HallB, HallC)

Log Number: 4487986Logbook(s): Entry Makers: dchriBody: 

Just a quick reminder of WHY DoEs iT Be MaSkEd?

BSY_3 bit 2
Vacuum Valves 1C00A, 1C05A
* 1C15A & 1C16 are masked because they happen to share a node-channel with 1C00A & 1C05A
* However, only 1C00A & 1C05A have an ABIL entry for masking
--> 1C beamline taken apart for MOLLER install

3H03
Hall C fast Raster B
--> Hall is only using 1 of 2 raster coils (coil B off, coil A on)

2H02
Hall B Solenoid
--> not being used

SL02
RF zone 2L02
--> seems like PSS functional test of 2L02 has yet to be performed?

2W01_1
Horizontal RF Separators

2L09-6 very high, unstable LO power

1 day 4 hours ago
Log Number: 4487978Logbook(s): Entry Makers: kpriceBody: 

Looks like this cavity has had high, unstable LO power for a long time. I don't know if there's such thing as too much LO power except that it might saturate at some point, though maybe the instability is worth noting. As seen in elog 4487960, there's some correlation between a period of cavity instablity and LO power instability. I couldn't say which thing caused the others, but the abnormally high LO power in cavity 6 stands out.
