10 pins lectrical check result after insulator is installed on water cap C.
pin 14 to 60kv bias has 20 Kohm @250V Megga check. The rest check on ohmmeter and megga @250 are either OLor over 25Mohm which are good. |

November 26, 2024 - Aaron Tam
Handover from TPO and inspection
- Completed
- Some modification to the center Inner-Outer conductor had to be made (hole enlarged as tab was slightly short)
Target Insertion:
Target Mounting:
- Upon fully seating UC#47 on service tray locating pins, the gas line VCR gasket came off
- Operator doesn't have line-of-sight to this area, so there has to be healthy clearance (Foreshadowing)
- Gas line VCR gasket reinstalled using manipulators
- 2nd seating of UC#47 on service tray locating pins, the gas line VCR gasket came off again
- Some alignment interference with the gas line coupling is the cause of the gasket falling off during placement (photo attached)
- Gas line on service tray was loosened, raised to highest position and fastened (Photo attached)
- Failed to re-install VCR gasket (Plastic separated from gasket material)
- Target removed from Hot cell to reinstall gaskets and make modifications to the gas-line coupling
- Gas line coil plastically deformed to give less of a spring action so the coupling can stay down under friction until it is time to couple
- Target carefully inserted into hot cell without disturbing spring/friction of gas-line coupling.
- This had to be repeated several times. Once for the waterline gaskets coming off, and a few other times to insert the target/tray without disturbing sprung coupling
- Target mounted without issue after the above steps successfully
Gas and Water Services:
- VCR connections coupled
- Leak test passed
- leak test faster today because module had been left in silo for a long time to dry out.
- Gas line no-longer needed, so was not checked
Electrical Services:
- Conductor bolts installed
- All bolts (including mounting bolts) checked for fit with mirror
- Coil conductor bolts torqued to at least 130inch-lbs
- Electrical test completed
Containment box panel reinstalled
Cleared area around module for craning out.

Tuesday, January 07, 2025, 12:05, David Wang, ITE, Standard Operation, TM3, UCx #47, ITE primary and secondary vacuum vessel leak check for 2025 shut down
|
ITE primary and secondary vacuum vessel leak check for 2025 shut down have been done. No leak. The TM3 waterlines helium pressure test will be done at TCS when module is there.
TM3 water lines helium pressure test are done. 70 psi helium 3 minutes to each line( except HS which has no target on it ) . leak detector base leak rate :0.0Xe-9 atm.cc/sec. No leak on all tested water lines.Helium were purged out after test. and 60 psi nitrogen were filled in lines for storage. |

Thursday, January 16, 2025, 14:21, David Wang, Conditioning Station, Standard Operation, TM3, No target, TM3 electrical check at TCS under good vacuum
|
A complete TM3 electrical check at TCS under good vacuum has been done. Pin 14 to 60KV only has 8K ohm on ohmmeter check , and it's about 2Kohm @250V Megga. It's low in resistivity. The pin 14 is for thermocouples only so no big concern. The rest things are good. See attachments. |

Friday, November 01, 2013, 09:08, Travis Cave, South Hot-Cell, Standard Operation, TM2, no target, module move
|
TM#2 has been moved from the north west silo to the south hot cell. The module has a field of about 3.1mSv/hr when it was lowered into the hot cell. |
|
Monday, November 04, 2013, 10:46, chad fisher, South Hot-Cell, Repair, TM2, , TM2 Exploration
|
TM2 is now in the hot cell with the containment box off for inspection and eventual blank off off the water blocks.
Upon initail inspection the status (fron a hot cell point of view) is:
-Water block jig is equipped/on
-There is a thermocouple line that will need to be removed
-TM2 requires a new front containment box cover - already manufactured and waiting for installation
