IG1S elbow o ring seal and a blank off cap o-ring seal beside the elbow were replaced on ITE entrance module top last Friday. IG1s has a higher than
normal reading so i leak checked entrance module top last Thursday and found leaks to 5x E-8 atm.cc/sec leak on one of (or both of )these two o-rings seals.
they are too close to identify exactly on which one was leaking so both o rings were replaced. other air to vacuum seal on entrance module are leak |

Tuesday, July 09, 2024, 16:14, Carla Babcock, ITE, Repair, , , Attempts to reduce ITE:EL trips from HV sparks 8x
|
ITE:EL has been tripping off due to HV sparks. Usually this also trips ITE:Q1/2. These are sitting in side-by-side racks.
The working theory is that HV sparks are returning to ground through the EL and quads, tripping them off. Possibly this is the result of a changed
low impedance ground path. How this change happened could be either something we did during shutdown or the changes we made in TM3, no clear evidence yet. |
