NA01B10 Trip Off

After looking at the Myaplot it appears that everything dropout at the same time. It might have been some kind of power cliche. I went out and power the trim rack back up locally, and turn it back over to Ops.

Field Emission variations in 1L07

21 hours 3 minutes ago
Log Number: 4523951Logbook(s): Body: 

NDX monitors at the ends of the 1L07 cryomodule exhibit daily dose rate variations (the range of up to about a factor 2), correlated with the rack temperatures. Other locations look stable.

Follow-up Re: LERF Rapid Access beacon reported beaconing while in Restricted Access

21 hours 58 minutes ago
Log Number: 4523925Logbook(s): Body: 

There appears to be a noisy probe on RM 209 (p2). This gamma probe is currently being addressed. Since the LERF does not currently have "Beam Authorization", the Rapid Access system has been taken off-line. The system will be restored upon repair of the malfunctioning unit, RadCon checklists complete, and when "JAM" approval is granted.

COMMENT ON Modify VFV2L27 Fast Valve Controls Chassis

22 hours 4 minutes ago
Log Number: 4523924Logbook(s): Body: 

Task slated to begin first thing tomorrow morning.

Hopes are that the chassis can be removed, modified and returned back to the rack before the end of the day.

Worst case scenario is we leave the temporary firmware at 2L26 SRF VAC Controls Chassis and reinstall fast valve chassis on another day.
Firmware will allow the beam operations by masking the fast valve, similar to what was done at 1L26.

PTW can't be placed on issue until IC 16752 is on issue. This will be done tomorrow when we remove the crate and bring it back to the TED.

LERF Rapid Access beacon reported beaconing while in Restricted Access

23 hours 4 minutes ago
Log Number: 4523902Logbook(s): Entry Makers: alexsBody: 

Radcon has been contacted and is on the way to investigate. All radiation monitors in the vault are not reporting any radiation levels that would be expected to activate the beacon, so a hardware malfunction is suspected, but out of an abundance of caution, all personnel have left the LERF vault, and the doors have been locked at the PSS station until Radcon gives the okay.
