Monday, January 09, 2012, 14:44, David Wang, ITE, Maintenance, TM4, , ITE and TM4 2012 winter shut down leak check is completed.
|
I did a vacuum leak check on all ITE primary vacuum vessel and secondary vessel.I also did a helium pressure test(80psi ) on all TM4 water lines. There
is no leak has been found.ITE and TM4 are both leak tight now.
ITE primary vacuum vessel and TM4 waterlines: |

Thursday, January 12, 2012, 14:32, David Wang, ITE, Repair, TM4, , TP2 on TM4 has been replaced
|
TP2 on TM4 has been replaced with a new turbo pump , I didnt reset the controller in electrical room.So this new pump start to run at 8083 hours
on ITE TP2 controller. The new TP2 pump properly started. It works fine now. |
|
Thursday, April 05, 2012, 10:30, David Wang, ITE, Standard Operation, TM4, , I moved 5 shielding blocks back to ITE this morning.
|
| MAA is secured .The ITE and MAA are ready for taking proton beam now. |

Thursday, April 26, 2012, 09:23, David Wang, ITE, Repair, TM4, , changed flow wheel on ITE TM4 contaiment box water circuit
|
The the magnetic field on ITE TM4 flow wheel was gone yesterday.So there is no water signal on this circuit. The water flow is fine ,and the wheel
is rotating. I removed 1 shielding block on ITE and replaced the old wheel with a new one.Now the containment box water signal is normal.The problem is
fixed.The shielding block is back. |
|
Thursday, April 26, 2012, 13:01, David Wang, ITE, Repair, TM4, , Replaced TM4 EE water flow wheel in ITE.
|
Due to weak magnetic field on TM4 EE water flow wheel, we have two times intermittent water signal on this circuit this morning. I replaced the old
wheel with a new one in ITE. I checked the signal frequency and strength.It looks fine now. |
|
Tuesday, May 08, 2012, 10:28, David Wang, ITE, Standard Operation, TM4, , Disconnected TM4 in ITE.
|
I disconnected TM4 in ITE. The heat shield water circuit is purged. I closed the water supply to ITE.Now, the water system only supply water to
ITW and the system pressure is 110 psi which is good.I visually checked S-tank sight glass,and the water level is stable comparing to last week. Also,
I visually checked the ITW water signals strength and stability on electrical panel from electrical room.Everything looks fine. |

Tuesday, May 15, 2012, 12:14, chad fisher, South Hot-Cell, Standard Operation, TM4, SiC#26, SiC#26 removal TM4 degredation 19x
|
SiC#26 was removed from target module #4 this morning. Target shows the now standard arc marks on the 9 pin connector housing...pictures to follow.
Of greater concern is the amount of "plating out" or "arc" marks on both the insulators and connductor of the TM4 source tray.
I will again warn that the source trays historically have a life expectancy, and that TM4 continues to show visual signs that the current |

Thursday, May 17, 2012, 14:08, Travis Cave, South Hot-Cell, Standard Operation, TM4, no target, module move
|
| TM#4 has been moved from the north east silo to the south hot cell for target installation. No problems with the move. |

Friday, May 18, 2012, 08:17, chad fisher, South Hot-Cell, Standard Operation, TM4, SiC#27, SiC#27 Installed
|
SiC#27 has been installed onto TM4. Fit was very good. All electrical connections double checked with mirror.

Friday, May 18, 2012, 08:37, David Wang, South Hot-Cell, Standard Operation, TM4, sic 27, leak check on heat shield circuit
|
Chad and I leak checked the heat shield circuit after sic 27 target installed. It took 20minutes to pump down the circuit to the leak
detector bottom scales. The leak detector is calibrated today,and all the vacuum lines and connections are leak checked by spraying helium. Chad sprayed
helium to each vc fittings for 2 seconds. There is no any response on leak detector . The test repeated one time and the result is same. Chad flushed |

Tuesday, May 22, 2012, 10:00, David Wang, Conditioning Station, Standard Operation, TM4, sic 27, helium pressure test on heat shield circuit
|
I did a helium pressure test on heat shield circuit. The leak detector is concected to the TM4 primary vacuum system.The IG1 is 1.1xe-6 torr,PNG4 is
1.5 x E-6torr,and IG4 is 2.1 XE-6torr.leak detector base leak rate:0.0xE-9 atm.cc/sec, base pressure is 0.0x E-4 torr.Applied 80psi helium to heat shield
circuit for 4 mins .There is no any response on leak detector during 4mins time. There is no pressure change during the test time. The heat shield circuit |
