Friday, January 26, 2024, 11:57, David Wang, Safe Module Parking, Standard Operation, TM4, , TM4 coil1, 2, and HS electrical check at SMP after module moving.
|
TM4 coil1, 2 and HS are all OL at 250V at SMP after module move. This week, Chad and Carl fixed short issue on coil1, 2 and HS by insert dropped ultem ring back to position at SHC. |

Friday, September 13, 2013, 08:05, David Wang, South Hot-Cell, Repair, TM4, , TM4 coil 1 leak check in SHC
|
Leak checked TM4 coil1 in SHC with Isaac . The leak detector only can pump down to 1.5xE-7 atm.cc/sec. The leak detector got the response once the helium valve is open, not even close to the leak area. The leak detector got a very big response when the helium probe was put close to the coil terminal block on target front side and spray helium for 2 clicks. The leak detector got a small response when the probe was put close to water block area and spray helium for 2 clicks. The leak is located on the front target side coil line but not from water blocks. The leak is too big to be further pin pointed by this method. See attachment |

|
TM4 and TiC#7 target electrical check and HS leak check at SHC after target installation have been done. all results are good. I will attach the checklist when printer is back to work.
TM4 HS line was helium pressure tested at TCS this morning. No leak. Also i leak checked TM4 top all air to vacuum seals at TCS. Everything is good.
TiC #7 is a febiad target.TM4 top has been configured for febiad target. checked pin 2-2 to bias, target ,and chassis at 250V. they are all OL.

|
TM4 and TCS vacuum system are connected. Turbo pumps are started. Everything is fine so far. |
|
Thursday, March 13, 2014, 07:35, David Wang, ITW, Standard Operation, TM4, , TM4 and ITW turbo pumps have been started
|
I connected ITW vacuum system to TM4. TM4 and ITW turbo pumps have been started successfully. The pumping down is good so far. |
|
Wednesday, March 19, 2014, 15:46, David Wang, ITW, Standard Operation, TM4, , TM4 and ITE air to vacuum leak check and TM4 water lines helium test. 7x
|
With TM4 located in ITW, All air to vacuum seals on ITW primary and secondary vacuum vessels have been leak checked with leak detector hooked directly onto the TM4 service cap.The base LR :00xE-9atm.cc/sec. The ITW IG1 was 1.16xE-6 torr which was good. No leak has been found during the checking.Also, the TM4 water lines(except HS) had been pressurized with 70 psi helium on each for 2 minutes. There was no response during the test. The ITW and TM4 are good on leak checking.See attachment pictures |

Friday, July 06, 2012, 14:38, David Wang, Conditioning Station, Standard Operation, TM4, UO#3, TM4 UO#3 target heat shield helium pressure check is done.
|
Connected leak detector to TM4 and CS vacuum system. The vacuum readings on TM4 and CS:PNG4 3.6 xE-6 Torr, IG1 2.3xE-6torr, IG4(diagnostic box) 3.9xE-6 Torr. Leak detector base pressure:6.0xE-3 torr, base leak rate: 1.0xE-9 atm.cc/sec. Applied 80 psi helium to heat shield circuit for 5 mins . There is no response on leak detector. The heat shield circuit is leak tight. |

Tuesday, June 07, 2016, 17:11, David Wang, Conditioning Station, Standard Operation, TM4, UC#16, TM4 UCx16 electrical check and leak check at SHC
|
Chad and I finished the TM4 UCx6 electrical check and leak check at SHC. Leak check result on HS line is good. There is a dead short between "Z" repellor and HS during the first time electrical check. The dead short disappeared after re- installation of UCx 14 target onto TM4. See attachment
Anders and I did another electrical check on TM4 at TCS under vacuum. See attachment 2 |
