 Friday, May 13, 2016, 10:08, David Wang, Conditioning Station, Standard Operation, TM2, , Helium pressure test on TM2 HS and window line at CS with new Lp Ta target
|
These two lines are passed helium pressure test this morning. The LD base leak rate 0.0 X E-9 atm.cc/sec. The base pressure 0.0 X E-4 torr. Helium pressure 70 psi. applied helium to both line for 5minutes each. No response on LD during the test. |

Friday, May 13, 2016, 10:12, David Wang, Conditioning Station, Standard Operation, TM2, , TM2 water lines, heaters, EE, and EL are connected at TCS.
|
The HV cover is installed on to TM2 after the connections. The HV key is returned back to B2 level. The TCS Faraday cage is locked. |
|
Monday, May 16, 2016, 11:16, David Wang, ITW, Standard Operation, TM1, , ITW, TM1 turbo-pumps are swithched off
|
I let isac opp switched off ITW turbo-pumps. The argon vent valve in electrical room is opened. The ITW argon venting will be started soon. |
|
Friday, May 20, 2016, 08:13, David Wang, Conditioning Station, Standard Operation, TM2, Ta#48, I switched off TCS and TM2 water system
|
Disconnected TM2 at TCS(vacuum system still on). Purged all TM2 water lines for helium pressure test. |

The bigger leak found on MSP before was gone. Leak rate are smaller on all circuits comparing to before.
The leak rate on 1 hour total lines test at 70 psi is better also which is 6.6 XE-8 atm.cc/sec this time. |

|
TM2 has been connected in ITW by Dan.M and David.W. All turbo-pumps have been started. Everything is good so fine. |
|
Thursday, June 02, 2016, 11:59, David Wang, South Hot-Cell, Repair, TM3, , 5K mega test on TM3
|
I did a 5KV mega test on TM3. Only5Mohm @5kV between coli line PQ and chassis(ground). It confirmed the close gap between P,Q and GE. Other lines are ok. See attachment. |
|
Tuesday, June 07, 2016, 11:36, David Wang, ITE, Standard Operation, TM4, Ta#47, TM4 has been disconnected in ITE.
|
Dan and I disconnected TM4 in ITE. HS water lines has been purged. |
|
Tuesday, June 07, 2016, 11:37, David Wang, ITE, Standard Operation, TM4, Ta#47, TM4 has been moved from ITE to SHC
|
Bill and Yasmine did the move. Everything is good. |
|
Tuesday, June 07, 2016, 11:42, David Wang, South Hot-Cell, Standard Operation, TM4, Ta#47, electrical check on TM4 with old Ta target at SHC.
|
I did an electrical check on TM4 with the old target still installed. The number is a little bit low on 500V mega check between chassis and 60KVbias which is 146Mohm. Others are good. See attachment
I wrote all OL to 0 in attachment 1 ohmmeter check. Please See attachment 2 for correction. |

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 |
