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. |

Monday, January 25, 2021, 10:57, David Wang, South Hot-Cell, Repair, TM4, , TM4 steers short investigation.
|
Cables were disconnected for steers in containment box. The Megga measurement (500V) result from the top of the module:
Left to right: OL, left to top OL, left to bottom OL, right to top OL, right to bottom OL, Top to bottom OL. And all of them to ground
are OL. No short on cables from module top to steers itself. The short should be inside the steers. It will be confirmed with directly test on steers. |

Wednesday, February 10, 2021, 11:34, David Wang, Assembly/Bench Test, Standard Operation, , , Old resin can and 2A window RH clamp field measurement at silo.
|
Old resin can: 0.5 meter 360 degree rotation above silo area, 350u sv/hr. On contact 3.0 to 3.5 msv/hr. It was replaced
during 2017 winter shut down, and stored in silo since then.
2a window RH clamp: 0.5 meter, 160 usv/hr. On contact, hottest spot 3.5msv/hr, general,1.8 msv/hr. |
Wednesday, February 10, 2021, 13:30, David Wang, Safe Module Parking, Standard Operation, , , TM2 and TM4 electrical check without targets. 
|
TM2 at SMP under vacuum. TM4 at silo. Frank and I did the tests. Everything is fine on TM4 check. On TM2, all mega test at 500V
are around 200K ohms which is so abnormal. We will move TM2 to TCS and start investigation there. |

|
The crane pendant for the main hoist was upgraded to a FLEX EX2 style pendant by Canco Cranes. The installation work was performed by Matt at Canco,
supervised by Tom Kauss, David Wang, and Adam Newsome. Installation work was performed in two phases since the initial installation did not provide adequate
range and an antenna issue needed to be resolved (I2021-01-14-1, |

|
TM3 old source tray, old target hall high active water resin tank, and old 2A window RH clamp are transferred from TH to cyclotron lower vault
basement 10 and 10A location for storage. They are placed beside and in front of old TM1 and TM2 source tray boxes which stored there in 2018. |

|
Edi and I inspected roughing pump ITM MP1, primary backup pump ITHMP1, and secondary backup pump ITHMP2. We checked oil level and color on all pumps.
Refilled lubricant to ITMMP1. ITHMP1 and MP2 oil level is fine. ITH MP1 oil color is darker than MP2. But, both them are ok still. Shielding block has
been restored after the job. |

|
The North Hot Cell gas delivery lines (labeled 1, 2, and 3 on the hot and cold side panels) were leak checked today. 5psi helium gas was
applied to each line in turn with the appropriate solenoid valve opened and a Staubli connector with plastic tubing and the leak check wand attached to
the matching connector inside the cell. The end of the wand was sealed using tape. The Agilent G8601 leak detector was used on "sniffing" |

First thing I entered into the NHC to install to the target kart mounting clip, and remove excess tools and materials from the hotcell
After the TM3 without a target was lowered into the NHC.
Once inside, with the use of the manipulators, I was able to remove the containment box door, place it on the swivel arm, move the arm out of the |
