Wednesday, March 30, 2016, 15:49, David Wang, Assembly/Bench Test, Repair, TM2, , TM2 Helium spray leak check on solder stems inside service cap on the top of SW silo. 7x
|
On each water circuit in side the service cap, there are 4 soldering stems which two of them are inside blue nylon insulator and other two are connected
to service tray. Each stem has two soldering spots. See attachment pictures for detail location. I sprayed 15 psi helium on each soldering spots on stems
for 20second on each circuit. I sprayed tons of helium inside each blue nylon.No any leak has been found during the check. The leak detector base leak |

|
A silo and blue steel frame are removed out of TH this morning. They are transferred through ante room, and moved to experimental hall TM assembly
area for a long term storage. Swipes are done on the silo and frame before and during move. No contamination has been found . |

Source tray is complete for brazing, gas line bracket is currently missing but can be made in parallel with tube bending operations.
Source tray water lines to be fabricated according to ITA6144 drawing set.

|
Two minor chips in the main 60 kV insulators on the source tray was inspected today by Anders, Tom and Aurelia. The chips are small enough that
they should not be a problem. See photos for details. |

|
The Source tray was inspected in the RH shop today by Anders, Friedhelm and Jens. The routing of the lines are satisfactory, however a design proposal
to remove the ground electrode line will be made. This design will have to ensure a proper connection from the electrode to ground (using the window cooling
lines). All other lines are OK at this point. Some fine adjustments are expected after brazing and soldering to maintain high voltage separation. Photos |

Thursday, October 31, 2019, 10:17, David Wang, Assembly/Bench Test, Maintenance, TM2, , Febiad target gas line leak check.
|
Feibiad gas line for ITE and its adapter fittings for TM2 are tested today by installing them on a dummy water stem. No leak on VCO fitting, adapter
o-rings, and all Swagelock fittings of this assembly. Manual valve on gas line works fine. The positional check on gas line between TM2 and ITW will
be fulfilled next Tuesday during module disconnection. |

|
The second module lifting assembly ITA0490 is moved into TH and installed onto TM3 . It will stay with TM3. I adjusted the CofG on the assembly.
It is same to the first lifting assembly we are using now. After adjustment, The installation of assembly on TM3 are smooth. |

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. |

|
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. |

|
Based on a request from CNL (attached), modifications were made to the wire ropes protruding through the tops of F-308s to add a crimped loop which acts
as a lifting feature. Tests were performed (report attached) on 10 sample units to validate the strength of these loops, since each loop could not be tested
in-situ once the pails were already packed in F-308s. CNL has reviewed and approved the test report. |
