Tuesday, September 20, 2016, 11:41, David Wang, ITE, Standard Operation, TM4, , TM4 has been disconnected in ITE.
|
TM4 has been disconnected in ITE. No water line purge on HS and 3 water circuits are looped after disconnection. The HALCW system resistivity is stable
before and after this disconnection. |

|
Chad and I leak checked the TM4 HS line after new target installation. base leak rate:0.0Xe-9 atm.cc/sec. No response on LD during the leak check.
The line is leak free so far. It will be helium pressurized at TCS late. |
|
Friday, September 23, 2016, 07:49, David Wang, Conditioning Station, Standard Operation, TM4, , TM4 has been moved and connected at TCS
|
| All TCS and TM4 turbo-pumps were started yesterday. Overnight pumping down is good so far. |

|
| All ITE turbo pumps have been started since yesterday afternoon. The ITE and TM4 pumping down is good so far. |
|
Tuesday, October 04, 2016, 09:18, David Wang, ITE, Standard Operation, TM4, , 5 Shielding blocks have been transferred from ITW to ITE.
|

Thursday, October 20, 2016, 14:17, Anders Mjos, ITE, Repair, TM4, SiC#34, HV enclosure inspection
|
The HV enclosure and module connections were inspected by David and Anders on Wednesday 19th in an attempt to find any HV problems causing the
high leakage current. One cable was cable tied to a copper conductor in the chase. Some small pieces of loose material were removed. No obvious problems
could be detected. |

Tuesday, November 01, 2016, 14:53, David Wang, ITE, Standard Operation, TM4, , TM4 was disconnected at ITE
|
TM4 was disconnected at ITE this morning. It was moved to SHC after. No alpha alarm issue has been happened during and after move. The ventilation
pumping down procedure on ITE was fulfilled during the move. |

Tuesday, November 01, 2016, 14:58, David Wang, South Hot-Cell, Standard Operation, TM4, , SHC, TM4 leak check on HS line.
|
Chad and I did a leak check on TM4 HS line with new Ta target installed. Base leak rate 0.0xE-9 atm.cc/sec. base pressure 0.0XE-4. splayed
2 helium to each VCR joints and did 10 seconds helium flush. No response on LD during the test. The HS line is leak free so far. It will be helium pressurized
at TCS later. |
