Follow-up Re: 1L26 Valve Closures

Log Number: 3644542Logbook(s): Body: 

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.

COMMENT ON Survey MQR6S03 for possible offset.

Log Number: 3644536Logbook(s): Body: 

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.

LCW Leak behind 1A15 Dipole Array

Log Number: 3644530Logbook(s): Body: 

During todays access a fitting behind 1A15 array was found to be leaking badly. Leak has been repaired and system back on line

COMMENT ON 1L20 Waveguide warm ceramic window installation

Log Number: 3644529Logbook(s): Body: 

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.

ced2Epics modified EPICS PVs

Log Number: 3644528Logbook(s): Tags: Body: The following control system variables were updated because they were detected to differ from their CED property counter-parts.
  • IHVIONNL1301SDV: found 1000; restored to CED value of 800

2A02 Dipole Stands Adjustment

Log Number: 3644527Logbook(s): Body: 

The 2 center stands in the 2A02 dipole arry were found to be out of position by 6 & 3.5mm. These have been moved back into place. S&A is re-aligning the dipoles.

Magnet Over Temp Checks & Repairs

Log Number: 3644526Logbook(s): Body: 

JD3A21, JC5A31 & JA9A20 were reported tripping on over temp. All 3 were found to have dead headed circuits. These have been fixed. EES was checking all the other dipole which were repaired and if any are found to need fixing this will be taken care of.
