Hi all, The old ITE TP3 pump is moved out and the new pump is in
postion .Since this time I used a new holding ring(1 piece) insead of old 2 pieces holding ring which are thicker than new ring, the old holding
bolts are a little bit too long for the thread holes on the ITE exit 1. I have to find the right length bolts for this new holding ring. The pump |

|
ITE TM3, entrance module, and 2A3 window flange seals have been leak checked this morning after 2 new seals replacement.The LD base leak rate was 0.0xE-9
atm.cc/sec, base pressure was 0.0 XE-4 Torr. I sprayed lots helium around the TM3, entrance module and 2A3 flange seals. No any response had been
found on LD during the spraying. All three flanges are sealed perfectly now. |

| ITE MSP water circuit flow wheel was replaced yesterday due to poor performance. |
Wednesday, March 08, 2017, 14:09, David Wang, ITE, Maintenance, TM2, , ITE IG1S increasing. 
|
By retrieving data further, It has been found no directly relationship between IG1S surging and dump plug water opening. Vacuum surging is 10minutes
ahead dump water supply to circuit. SEE attachment 1. Also, The ITE IG1S start to behavior unusual in middle of Feburary. See attachment 2. Today,
ITE IG1S is still slowly climbing up. I decide to leak check ITE vacuum vessel. Before leak check, for more information and trouble shooting. I closed |

Friday, January 22, 2021, 12:34, David Wang, ITE, Standard Operation, , , ITE HV test.
|
ITE annual HV test is done. No module in station. The bias power supply has been ramped up to 49KV on control page. We still have voltage limit issue
on this PS at 48KV so it only can go to 47.7 KV on PS panel. No major spark during test.. The test result is same as last year test which was did in March
2020. |

Thursday, February 10, 2022, 12:42, David Wang, ITE, Standard Operation, , , ITE HV test woithout mdoule was done.
|
Carla did the test. That is what she wrote in Feb 04th: "I am done with the HV testing at ITE - the
results were the same as at ITW. It stayed at 59kV for 30 mins with no issues. Trying to go above 59.5kV is probably possible but a bit more risky. ITE
also has a band, from 54-56kV, where the current jumps around like crazy". |
|
Wednesday, March 04, 2020, 11:52, David Wang, ITE, Standard Operation, , , ITE HV test without module
|
ITE bias test is done to 48KV. No spark. We can not raise bias above 48KV. It looks like we have a current limit issue on control system when testing
above 48KV. John Cow checked current limit on PS locally. It is set to 8mA which is much higher than the test current. Isac operator issued an e-fault
to control group. |

Tuesday, May 02, 2023, 17:18, David Wang, ITE, Standard Operation, , , ITE 4 turbopumps are started for preoperation check.
|
ITE TP3,4, 1S,and 4S were started successfully this afternoon. All pump current draws were below 1.5A . IG1S was switched on. I have no local controller
so TP1 and TP2 on TM4 at MSP can not be checked. IG1S was hard to switch on at first. It timed out and showed error 09 code. I removed the
connector back cap, and it could be switched on after. I will look on this issue. |

|
The 4" PVC drain line in the ISAC-1 active sump was modified so that the drain pipe terminates below the low level water line of the automatic pump-out
system. This will prevent backflow of sump gasses into the SHC, NHC, or TCS space if the air pressure in any of those rooms are lower than the sump
air pressure. The details of the modification were specified by Mechanical Services Group, and the work was done by Paul Jensen. This system |

Tuesday, August 15, 2017, 12:10, Isaac Earle, North Hot-Cell, Development, , , ISAC Active Sump low water level measured
|
The ISAC active sump in the Active Service Room (#002 on B2 level) was pumped out yesterday using the standard procedure (Section 5.5.2 of the ISAC Operators'
Manual, V1.0). The procedure makes use of the auto stop feature of the pump-out system which stops when a low level float switch is triggered. The
water level was measured after pumping stopped, and was found to be approximately 21" above the base of the sump. A new section of pipe will |
