Log Number: 4543393Logbook(s): Entry Makers: jhowardBody: 

Main machine in Power Permit. North Linac has been surveyed the set back to Power Permit. With Faraday Cup #2 locked in and RF placed in local mode (no beam or RF in the segment since the survey), the survey is still good.

RF in Inj, NL, and SL are in local mode.

All PSS interlocked Box Supplies are off.

Hall C has been surveyed and left in Controlled.

All other segments have not been surveyed.

Vacuum (AA region) alarm. spurious/common spikes, alarms cleared soon after

3 days 14 hours ago
Log Number: 4543373Logbook(s): Entry Makers: dchriBody: 

(FIG.1,2)
AA[08,14,16,17] vacuum alarm came in,

(FIG. 3,4,5)
Before I could plot & pull up the vacuum spikes, the alarms & levels resolved themselves.
Seems to be a common spike which happens ever so often. Quickly drops back down soon after to nominal levels (last image)

Regardless I'll keep an eye on it throughout the night.

Anyone know what/why this occurs?

Seems to be a common spike which happens per week or so. Quickly drops back down soon after to nominal levels

Regardless I'll keep an eye on it throughout the night.
