|
Thursday, December 21, 2023, 09:36. ITE multipin wires 12-13-14-15 were rewired from the RF driver box to a TC datalogger inside the HV cage. A
webcam was also installed to monitor the TC values during operation. This is only a temporary setup to be upgraded during shutdown. |

|
West target station is setup to use argon for tank venting. There is 1200 PSI remaining on argon bottle in electrical room. That is sufficent
for venting west target station to atmosphere twice. ISAC Operations has been previousily contacted and their procedures for venting remain the same
except that they can not rely on ITW:CG4S to determine when at atmospheric pressure. I have asked them to contact me if an unscheduled vent is required. |

Friday, June 08, 2012, 15:03, Don Jackson, South Hot-Cell, Standard Operation, TM1, Ta38, Electrical Check on new Ta38 at hot cell
|
Megger checks were exceptionally high (good). Readings taken less than 2 hours after reading low values from end of run on Nb#6. Tests
on Ta38 will be repeated at conditioning station later. |

Tuesday, December 19, 2017, 10:40, Don Jackson, Crane, Maintenance, , , Crane Power during winter break
|
The power to the crane and controls were turned off using the power switch in the Crane Control room. The main disconnect switch in the target
hall was not touched.
All site power will be off for a period of time during the Christmas break and this removes the crane from any issues when power is restored. |

Tuesday, October 01, 2019, 09:23, Don Jackson, ITE, Maintenance, TM2, ZrC #8, 60KV Common Connections
|
1 Jumpers between 60KV common and FEBIAD lines were connected in an unusual way. This should of had no impact on the ZrC run but would have to
be corrected for any future FEBIAD runs.
2 Feedthrough U was mislabeled (label has been removed) |

Tuesday, November 01, 2011, 11:50, David Wang, Conditioning Station, Standard Operation, TM4, , TM4 leak test on conditioning station
|
I did a leak check again on TM4 today. This time, the leak detector pump to the bottom on both base pressure(0.0xE-4 torr) and base leak rate(0.0xE-9
atm.cc/sec). All high vacuum gauges on TM4 and conditioning station at -6torr range.IG1 is 3.3-6torr,PNG5(top of service cap)is 6.5-6 torr, and the PNG4(bottom
of the vessel )is 8.7-6torr. For air to vacuum leak checking, I checked the panel we moved last week on service cap by spraying helium around the panel. |

Monday, November 21, 2011, 13:49, David Wang, Conditioning Station, Standard Operation, TM1, , TM1 full leak check in conditioning station
|
TM1 full leak check in conditioning station has been fulfilled this morning.Both air to vacuum leak check and waterlines helium 80psi pressure test are
fine.The result:
Air to vacuum helium spray:base leak rate on leak detector 1.6x E-9 atm .cc/sec.base pressure0.0xE-4 torr. sprayed helium around all flanges, turbo |

Monday, January 09, 2012, 14:44, David Wang, ITE, Maintenance, TM4, , ITE and TM4 2012 winter shut down leak check is completed.
|
I did a vacuum leak check on all ITE primary vacuum vessel and secondary vessel.I also did a helium pressure test(80psi ) on all TM4 water lines. There
is no leak has been found.ITE and TM4 are both leak tight now.

Thursday, January 12, 2012, 14:32, David Wang, ITE, Repair, TM4, , TP2 on TM4 has been replaced
|
TP2 on TM4 has been replaced with a new turbo pump , I didnt reset the controller in electrical room.So this new pump start to run at 8083 hours
on ITE TP2 controller. The new TP2 pump properly started. It works fine now. |

Monday, January 16, 2012, 09:30, David Wang, ITE, Maintenance, , , Changed all old inducion coils for flow sensors in ITE
|
I had changed all old induction coils for flow sensors in ITE .I checked all ITE water signals on control boards in electrical room.They are all very
stable and constant.All ITE inductions coils work fine now. |

Wednesday, February 01, 2012, 09:54, David Wang, ITW, Maintenance, TM1, , ITW and TM1 winter shut down vacuum leak check
|
ITW and TM1 winter shut down vacuum leak check had been finished yesterday.All ITW primary vacuum vessel, secondary vacuum vessel, and TM1water lines
had been leak checked.No any leak has been found .The ITW and TM1 are both leak tight.Some detail information below:
TM1 and ITW primary vacuum vessel and water lines: The leak detector was hooked on BV2 after TP2. Calibrate leak detector.leak |

Monday, April 02, 2012, 08:17, David Wang, Conditioning Station, Development, , , conditioning station IMC pump down.
|
I pumped down conditioning station IMC today. The inside bellow pressure is -20 psi on the gauge.Visually checked the bellow before and after pump.The
bellow is in retracted condition now. |

Tuesday, April 03, 2012, 12:11, David Wang, Conditioning Station, Development, , , leak check on conditioning station vacuum system
|
I did a leak check on conditioning station vacuum system today.The vacuum system had been roughed over night . This morning before the leak check,the
convectron gauge reading on emittance box is 20m torr which is reasonable. I hooked the leak detector to system (without turbo pump on)
. The leak detector showed base LR 6.3xE-8 atm.cc/sec. At this base LR, I found 2 leaks up to low E -6range on that cross tube flange to small turbo pump, |

Thursday, April 12, 2012, 14:40, David Wang, Conditioning Station, Development, TM1, , conditioning staion and TM1 is under TP1 and TP2 pumping now.
|
TM1 moved to conditioning station to today. After moving, I connected the vacuum system which include all gauges ,vacuum lines , controllers,and fans.I
started roughing the station through two turbo pumps(on TM1) . After 2 hours roughing, the station vacuum went to 100 mtorr. I started TP1 and TP2 on TM1
and turned on 3 gauges (png1 on service cap, ig1 on service cap ,and png4 on emittance box) . All turbo pumps and high vacuum gauges work fine .The |
