|
both high active pumps ITC:MP1 and MP2 are refurbished by RH group Maico and Peter. Pumps have been installed back to system with new inlet/outlet flange
gaskets. high active water surging tank is refilled with water and pumps were primed. I asked operator to switch on pumps separately. Both pumps work fine.
They are quiet and pumps discharging pressure is a little bit better comparing to before refurbishment. Nitrogen gas is injecting into system. O2 level |

|
water are supplied to both ITE and ITW. I did a general inspection on HALCW system. Two small leaks on 2" shut off valves are fixed. No other leak
has been found so far. all water flow meters work fine. MP2 pump discharging pressure is ok which is just above 100 psi on local gauge reading. pump noise
are low. pump body temperature is less than 45C which is good. |

|
ITW gas lines pumped down to 2e-3Torr on leak detector with leak rate in the low e-7 atm-cc/s. Gas bottles opened at 3psi and labels in epics changed
to reflect correct setup. switch box set to cathode mode, checked that anode wire was at HV common.
note ballast is removed from ITW now to be used in ITE so that line is blanked off. |

Tuesday, June 04, 2024, 11:44, Carla Babcock, South Hot-Cell, Development, , empty LP FEBIAD, investigation of cathode short on empty LP FEBIAD
|
On May 30 Aaron, Chad and I removed the empty LP FEBIAD target from the SHC into the anteroom to attempt to find out the source of the cathode short
observed online. The behaviour online was that a connection of several hundred ohms was preventing the cathode from being biased. The resistance was still
enough to allow us to run in anode mode, which is what we did. I am not sure where the cathode short came from but there was significant sparking on this |

Monday, June 17, 2024, 07:36, David Wang, ITE, Repair, , , IG1S elbow oring seal and a blabk off cap oring seal beside the elbow were replaced on ITE entrance module top..
|
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 |
