Odd 0L03 Detuning correlated to foreline vacuum

13 hours 8 minutes ago
Log Number: 4471689Logbook(s): Entry Makers: samariBody: 

It seems that the foreline vacuum pressure is tied to the detuning in 0L03. The turbo pump was recently replaced on the 6th, and all of the cavities are detuning at an ~80 minute interval starting on the 10th after a larger pressure spike (fig 4). As can be seen, the .0002 torr oscillation is correlated to the detuning in figs 1 through 3). I am not knowledgeable enough to understand how this could be happening.

COMMENT ON RF work for 2026 HCO

14 hours 35 minutes ago
Log Number: 4471676Logbook(s): Body: 

2L12-1 RFCM and comm. issue repaired, 2L14-2 KMAI issue fixed and RFCM comm. issue repaired (zone in HV). 2L18-4 RFCM replaced to fix HV enable faults. 2L08-8 HV enable repair fixed to un-bypass cavity and get zone back to HV. Zones 2L12 and 2L18 will need PSS locks off maybe tomorrow in beam permit to check repairs done today. 2L12-1 also had a KMAI tripping zone HV but I think I know whats going on after correcting 2L14-2 KMAI. More T/S tomorrow.
