VIP1L26B definitely faulted and took the zone down.
Perhaps the F/S/L lights are tied to the incorrect bits and are showing the instantaneous state rather than the latched state, which would mean once the ion pump recovered on its own (in this case it only took a few seconds, likely before you looked at the screen), it would appear nothing is faulted.
I will look into this and correct it if this is the case.
Using a machinist level, I sampled several dipole stacks in
the east and west arc and found potential leaning stand
candidates. In every instance the bubble was pegged
indicating a clockwise roll looking downstream.
Insulating vacuum leak check good. No leaks detected.
Flooded everything on the cryomodule with helium.
New insulating vacuum cold cathode gauge installed & cabled up.
reinstalled insulating vacuum pump on the cryomodule. The
pump will stay at location actively pumping on the cryomodule.
