RE: 2L11-3 CWWT

Log Number: 3589642Logbook(s): Entry Makers: michaelmBody: 

Warm sweep IR sensor on poly windows; Wmin (warning) at 70% of nominal 9.9V, Fmin (fault) at 60% of 9.9V.

As noted in attached, it was at 10.3 and generating CWVF faults in the 3/4 shared WG too. In looking at the history, it looks like it's been bouncing back and forth between the 5-6 MV range and the 9-10 range. Will attempt to set back up at 5 MV/m when SL recovers.

downstream beamline o-ring. This will be packed with monkey

sublimated away during the warm up.

Task Approved and is ongoing.
