We tested the leaks in GV12's gate o-rings by flooding the gate annulus with dry N2 (with active turbo connected and ready to be valved in to evacuate) and discovered the adjacent volumes' pressures rise too high too quickly. The Y2 beam tube rose to 7e-8 Torr and CP4 side rose to 1.4e-6 Torr in less than one minute. We may try to jog the gate on Monday to see if we can get a better seal, at least on inner o-ring. Will also re-evaluate the bake enclosure dimensions so see if gate annulus tubing can stay (GV11's definitely gets in the way and had to go).

We realized that we did not get any email or text alarms when we should have - pressure was well past the 5 minute and 15 minute set point thresholds on PT-245B and PT-256B. Will contact Dave B. about this.
