Today TM3 HV conditioning went up to 65kV. I'll leave it here over night. ISAC OPS have instructions to keep an alarm on the HV, and ion gauge and turbo
pump (TP2 tripped 3 times due to sparking). |

Friday, May 05, 2017, 11:53, David Wang, Conditioning Station, Repair, TM3, , sparking on TM3 serice cap top.
|
Sparking was found this morning inside HV cover on TCS in TH while TM3 was HV conditioning at TCS. The TCS bias was set to 50KV when I found this spark.
It sparks between HV cover front side wall to a KF 25 clamp on HS water terminal. The KF 25clamp is used in this situation on HS water line top because
the HS line is opened inside module, and we need a vacuum seal on the top of this line. Actually, The clap is much smaller than the corona ring on |

Friday, May 05, 2017, 11:06, David Wang, Crane, Standard Operation, TM3, , TH crane is used for 5 shielding blocks transferring.
|
TH crane is used for transferring five shielding blocks(30000lbs) today. All brakes work fine. Mostly, I do not need crane slow up motion for
this job so during 1 hour moving, no rattle sound and burning smell has been found. I think TH crane is good to use as we decided. |

Thursday, May 04, 2017, 19:10, Aurelia Laxdal, Conditioning Station, Repair, TM3, no target, TM3 HV test at TCS up to 50kV
|
Today TM3 was conditioned up to 50kV. At 50kV sparking started and to go higher in voltage it needs more conditioning time. Lowered it to 49kV for the
night. |

Thursday, May 04, 2017, 14:06, David Wang, Conditioning Station, Repair, TM3, , A vacuum to air leak on TM3 service cap round side panel was found and fixed..

During TM3 roughing down yesterday afternoon,The vacuum gauges CG1 and CG1S stopped at 1.20 torr and refused to drop down. Leak detector was used to
found where the problem was. LD was in rough detecting mode and showed 2.7xE-6 atm.cc/sec as base leak rate. Spray medium amount of helium to TM3
service top, and found this leak was on round panel of TM3 side wall. LR climbed to E-4 atm.cc/sec range on helium spraying. In my vie,One 10# socket head |

|
The window cover panel has been installed on the hot side of the NHC shielding window according to drawing IRH1638. It was necessary to drill
and tap a hole in the steel frame first to achieve proper grounding for stud welding. The strength of all studs were checked by installing a nut
on the stud tightened against a block up against the steel frame, which was then torqued to a minimum of 10 ft*lbs. For the final installation the |

RU( coil 1), F (anode), and 60kv bias(HS, Gasline, and MSP) are shorted together. Other lines are good. They are measured between individual
line each other @500V. The megga showed OL. All of them to ground are OL @500V as well. EL is grounded during check. |

Monday, May 01, 2017, 12:32, David Wang, Crane, Repair, , , TH crane burning smell
|
TH crane burning smell showed again this morning. It appeared after 1-1.5 hours of continuously using during the F308 flasks moving in TH.After a certain
time of using I think the brake gap is reduced because of thermal expansion. The main hoist and brakes work fine still. We knew these brakes gap
are tight especially on west side. So, It is not surprised that this burning smell appeared again. It does not affect the safe of crane use in my view. |

TCS:MP1 was tripping of intermittently yesterday. It was found by Dave Morris that the current sensor was not set correctly causing the pump on status
to flicker at times. Dave adjusted the settings yesterday. The system should be operational and is currently running normally. |

Installation of the NHC right side manipulator was completed yesterday. The three piece manipulator was assembled in the module assembly
area on the manipulator cart which was then craned through the hatch to the NHC service area (the slave end had to be removed for it to fit through the
hatch). The installation went relatively smoothly except for the second (cold side) piece of lead shielding around the thru tube which would not |

|
A video inspection of the lower service tray was performed this morning. Camera was inserted upwards into the service tray/service chase from the containment
box. One potential spark mark was identified as well as epoxy not flush with insulator. Fiberglass does not extend into service tray/chase much and does
not look, from initial inspection that it will be too difficult to remove. |
