Tuesday, June 17, 2014, 10:46, David Wang, ITW, Standard Operation, TM1, UC#9, 5 Shielding blocks have been transferred from ITE to ITW.
|
5 shielding blocks have been transferred from ITE to ITW. ITW is configured to take proton beam. Argon venting system for ITW is ready also. |
|
Wednesday, July 16, 2014, 11:28, David Wang, ITW, Standard Operation, TM1, , TM1 had been dsiconnected in ITW.
|
The TM1 and ITW were vented with argon gas last night. TM1 had been disconnected in ITW this morning. |
|
Wednesday, July 23, 2014, 13:36, David Wang, ITW, Standard Operation, TM1, , TM1 in ITW.
|
TM1 has been connected in ITW . The new roughing pump replaced on last Friday works good. I started all turbo pumps in ITW. The ITW TP1 controller was broken during the starting time. Dimo and I changed a new controller for ITW TP1 in electrical room. The pumping down is good so far. ITW water supplies to TM1 only. |
Monday, July 28, 2014, 17:26, Ron Kuramoto, ITW, Repair, , , ITW:IV5 Air leak repair 
|
Air leak was found at the Solenoid control valve located in the Pre-Separator & DB0 room. The gasket between the solenoid body and its manifold block was broken, see attached photos. The gasket and solenoid body were replaced. Air was turned back on to IV5 (B/L gate valve) with no apparent air leaks. The gate valve was actuated open & closed from the control room seeing both limits successfully.
Repair was done by Dimo Y. who received 0.01 mSv, and assisted by Anthony I. & Ron K. who both received zero dose.
Rad fields measured by RPG were; 1300 uSv/hr above B/L and 350 uSv/hr @ the Solenoid valves at knee height.

|
Removed ITW HS and COIL flow rate monitors installed at the beginning of this year. They were installed on these two circuits for testing.They are broken during last run in ITW due to radioactive field. |

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 are from one of the connections on primary BVs. I let Paul opened the BVs one by one,but the problem did not show again. Now ,the current draw on the turbo pumps are back to normal also.
I will keep monitoring the system and take a look on all KF25 clamps on BVs once I have a chance to access to ITW. |

Thursday, November 13, 2014, 14:01, David Wang, ITW, Repair, TM1, , I replaced flow wheel and coil on ITW MSP water flow sensor.
|
I replaced flow wheel and coil on ITW MSP water flow sensor which is located in ITW pit. Before replacement, I checked the signal strength and frequency form e-board on this circuit. The signal was good in 10minutes watching. Still, I replaced them. The flow sensor works fine after replacement. I made a comment on Isac e-fault system about this issue. |

Tuesday, February 17, 2015, 13:07, Anders Mjos, ITW, Development, , , Resistance measured of TGHT and TBHT lines to ITW
|
See e-log entry for ITE for details. The copper bars have not been removed. They can be used for testing the new power supplies.
Local measurement was done by Ray with a voltmeter. The voltmeter was consistent with EPICS readback and local readback on the power supplies. A voltage drop of 0.137 V @ 580 A was measured across the bus bar from the TGHT power supply to the cooled transmission lines. |
