Tuesday, July 03, 2012, 12:26, Travis Cave, South Hot-Cell, Standard Operation, TM4, SiC#27, module move
|
| TM#4 with SiC#27 moved from the east station to the south hot cell. Fields at East MAA were 127mSv/hr and the fields at the south hot cell was 77.5 mSv/hr. |
Wednesday, July 04, 2012, 11:33, Travis Cave, South Hot-Cell, Standard Operation, TM4, UO#3, Electrical check 
|
Electrical check of TM#4 with UO#3 attached at the south hot cell see attached PDF for full results. It has been noted that the Anode to 60kV common
is of a low value after consulting with Friedhelm Ames it was determined will will run with what we have. |

Wednesday, July 04, 2012, 13:18, David Wang, Conditioning Station, Standard Operation, TM4, uo#3, leak check on heat shield circuit
|
Chad and I
leak checked the heat shield circuit after uc#3target installed. It took 5minutes to pump down the circuit to the leak detector bottom scales. All
the vacuum lines and connections are leak checked by spraying helium. Chad sprayed helium to each vcr fittings for 2 seconds. There is no any response |

Wednesday, July 04, 2012, 14:16, Travis Cave, Conditioning Station, Standard Operation, TM4, UO#3, module move
|
| TM#4 with UO#3 moved from the south hot cell to the conditioning station. The fields of the module at the hot cell was 74.4 mSv/hr. |

Friday, July 06, 2012, 09:24, Travis Cave, Conditioning Station, Standard Operation, TM4, UO#3, Electrical check
|
| Electrical check of the target was done at the conditioning station under vacuum, see attached file for details. |
|
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. |

Monday, July 09, 2012, 10:51, Travis Cave, ITE, Standard Operation, TM4, UO#3, module move
|
| TM#4 with UO#3 from the conditioning station to the east target station. Move went well. |

Thursday, July 26, 2012, 08:33, David Wang, ITE, Standard Operation, TM4, , I moved 5 shielding blocks from ITW to ITE thisTuesday morning .
|
All water interlock checks for ITE had been done. The ITE water signals strength and frequency(Espcially on MSP circuit) had been checked from
electrical room, and everything is good. |
|
Thursday, August 30, 2012, 13:57, David Wang, ITE, Standard Operation, TM4, , Disconnected TM4 in ITE.
|
| I disconnected TM 4 in ITE on AUG 29th morning.The vacuum lines stay untouched and they will be disconnected on SEP 04th. |
|
Tuesday, September 04, 2012, 11:11, Travis Cave, South Hot-Cell, Standard Operation, TM4, UO#3, module move
|
| TM#4 with UO#3 has been moved from the east target station to the south hot cell for a target exchange. The move went well. |
|
Tuesday, September 04, 2012, 14:34, David Wang, South Hot-Cell, Standard Operation, TM4, NiO #1, TM4 heat shield circuit leak check with NiO#1 target
|
Chad and i did a leak check on TM4 heat shield circuit with new NiO#1 target installed. It took about 40 mins(much longer than usual) to pump down the
circuit to leak rate 0.6x E-9atm.cc/sec and 0.0x E-4 torr o leak detector.
All vacuum lines and joints which connected to the leak detector had been helium sprayed and they are leak tight.Chad sprayed helium on each |

|
| TM#4 with NiO#1 has been moved from the south hot cell to the conditioning station. Move went well. |

Wednesday, September 05, 2012, 14:36, chad fisher, South Hot-Cell, Standard Operation, TM4, NiO #1, UOx removal NiO installation
|
UOx was removed from TM4 yesterday and NiO#1 installed.
Video was taken.
Main stand-off insulators continue to deteriorate. |
|
Wednesday, September 05, 2012, 14:40, Travis Cave, Conditioning Station, Standard Operation, TM4, NiO#1, Electrical check
|
See attached PDF for details. 60kV Common to the target is low at 343k but I've been told will work. Test will be done again on Friday after it has sat
a few days under vacuum. |
|
Friday, September 07, 2012, 08:54, David Wang, Conditioning Station, Standard Operation, TM4, NiO #1, TM4 NiO #1 target heat shield helium pressure check is done.
|
leak detector pumped down to 0.0xE-9 atm.cc/sec, and 0.0xE-4 torr. All high vacuum gauge readings at CS and TM4 are at low -6 range from 2.2xE-6torr
to 4.2x E-6 torr. Applied 80 psi helium to heat shield circuit for 5minutes and there is no any response on leak detector. The heat shield circuit
is leak tight. |

|
| Electrical check of the TM#4 with NiO#1 was done again today. see attached file for results. |
|
Wednesday, September 12, 2012, 07:00, David Wang, ITE, Standard Operation, TM4, NiO #1, ITM4 in ITE connected and pumping down
|
TM4 had been connected in ITE. Six turbo pump had been started . thepumpming diwn is very good so far. The water interlock check on ITE and TM4 had been
finished and everything is good.All water signals are strong and constant by visually checking. |
