|
5 gallon spent target pail, lifting long pole and hook assembly load test was done by Rupan, Keyur ,and David. Load in pail 101 lbs, test
time 10 minutes. No deform on pail( pail OD 29.8mm is not changed before and after test. The test passed. Also 50 lbs load test on empty tray transit
frame was done. The frame is good on test. Rupan will have a test report on this job. |

Thursday, November 06, 2014, 08:55, David Wang, ITW, Repair, TM1, ThO#1, primary vacuum back up pressureITH CG1 ,CG2,CG4A were high.
|
I found primary vacuum back up pressure ITH CG1, CG2, and CG4A were unusually high this morning. They should be about 10 -20 mtorr after one night pumping,
but all of thier reading were 340-350-mtorr. Thease cause the current draw on primary turbo pumps were all over 2.0A(should be about 1.0A). I let Paul
closed all BVs on primary side . The pressure dropped quickly to normal range after all BVs were closed. This shows the back up line are good. The problem |
Thursday, June 04, 2020, 10:40, David Wang, Conditioning Station, Maintenance, , , Three manual valves are closed on TCS water system 
|
Three manual valves are closed on TCS water system return line in experimental hall. See attachments. It is for TCS TK2 water level slow drop trouble
shooting. These valves will be opened again right after troubleshooting.
TCS TK2 water level no change(11.1 inches) in this week after valves are closed. I will keep these three valves closed for one more week. |

Wednesday, March 25, 2015, 14:34, David Wang, Conditioning Station, Standard Operation, TM4, Ta#45, TM4 and CS turbo- pumps are started .
|
I connected TM4 and CS vacuum system after TM4 move. CS roughing pump was started first this morning. Later, Anders, Bill and I started 3 turbo pumps
on TM4 and CS. The pumping down is good so far. The CS vacuum system ion gauges are turned on also. |

Thursday, August 11, 2016, 10:37, David Wang, Conditioning Station, Repair, TM3, , TM3 service tray cover plate ITA2108 has been removed.
|
Requested by Aurelia, and approved by Friedhelm, TM3 service tray cover plate ITA2108 has been remove out of the module. The plated is checked for active
and contamination after removal. Then,It is double bagged, sealed , tagged, and placed downstairs in TH between south wall and green block . The
ram contact reading on the plate is about 10 usv/hr. We will do anther TM3 HV test at TCS without this cover plate. |

Friday, June 27, 2014, 10:16, David Wang, Conditioning Station, Standard Operation, TM3, , TM3 HS water lines helium pressure test. at CS
|
TM3 HS water line helium pressure test is done at CS. 70 psi helium , 3 minutes.Base LR 0.0xE-9 atm.cc/sec, base pressure 0.0xE-4 torr. No response.
The line is leak free. |

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 |
