|
There was an external water leak in ITW during the last beam running time. The leak started after the shielding blocks transfer(May 22). It cause a constantly
water level drop on S-tank(0.5 "/day average). Today , after the blocks are moved , the leak source has been found. Water seeped through a fitting
on ITW dump circuit pressure gauge. The leak water slowly flow around the TM1 on the tank flange. most of them are dried out, but left some stain on dump |

|
| TM#1 with UC#12 has been moved from the west station to the south hot cell. |
|
Tuesday, June 30, 2015, 15:41, David Wang, ITW, Standard Operation, TM1, , TM1 was disconnected in ITW this morning.
|
| TM1 was disconnected in ITW this morning. The ITW was vented with argon last night. |
|
Tuesday, July 21, 2015, 12:38, David Wang, ITW, Repair, , , ITW external water leak on dump circuit has been fixed.
|
| The leaking 1/8 NPT(M)-1/4NPT(F) adapter on the ITW dump circuit is replaced. |

|
| TM#2 with ZrC#7 has been moved from the conditioning station to the west target station. |

Tuesday, September 01, 2015, 10:38, David Wang, ITW, Maintenance, TM2, , ITW top tank flange clean up and r-ring replacement.
|
During last run， ITW dump circuit had a water leak on an adaptor below the pressure gauge. The top tank flange, slot, and O-ring were water contaminated
by the leak. I removed the old o- ring, cleaned up the flange and o-ring slot, and put a new o-ring into the flange. Some pictures will be attached
in this mail later. |

Tuesday, September 01, 2015, 14:54, David Wang, ITW, Standard Operation, TM2, , TM2 has been connectec in ITW.
|
TM2 has been connected in ITW. During the connection, Anders and I found the TM2 high current cables used in ITE and CS are short in ITW.
Anders and Grant found the original TM2 ITE high current cables in target hall. We replaced them. They works fine. But, a little bit longer on cable length
would be easy to connect them. All other connections and HV cover in ITW work for the TM2 so far. |

Tuesday, September 08, 2015, 10:11, David Wang, ITW, Standard Operation, TM2, ZrC, 5 Shielding blocks have been transferred from ITE to ITW.
|
| Maico and Dan moved 5 shielding blocks from ITE to ITW. The ITW is configured to take proton beam. |

Wednesday, October 14, 2015, 12:42, David Wang, ITW, Standard Operation, TM2, ZrC#7, TM2 has been disconnected in ITW
|
| Dan and I disconnected TM2 in ITW this morning. |
|
Wednesday, October 14, 2015, 12:44, David Wang, ITW, Standard Operation, TM2, ZrC#7, TM2 has been moved from ITW to SHC
|
| Bill and I remotely removed TM2 from ITW to SHC. The move is smooth. |

|
| TM#2 with SiC#32 has been moved from the south hot cell to the west target station. |
|
Tuesday, October 20, 2015, 12:49, Dan McDonald, ITW, Standard Operation, , SiC#32, Tm2 hook up In ITW
|
Lower and disconnect TM2 from crane in ITW, proceed with hooking up TM2 as per checklist with Anders. Double check flow meters and coils, reset TP1 and
TP2 |

Thursday, February 25, 2016, 09:27, David Wang, ITW, Standard Operation, TM2, , TM2 has been disconnected in ITW
|
| TM2 has been disconnected in ITW (except vacuum lines). The vacuum system is still operating. |
|
Wednesday, March 02, 2016, 09:51, David Wang, ITW, Standard Operation, TM2, , all water lines on TM2 and TM4 are purged.
|
| All water lines on TM2 and TM4 are purged for upcoming water lines helium pressure test. |
|
Wednesday, March 02, 2016, 10:04, David Wang, ITW, Standard Operation, TM2, , Leak check on ITW and TM2.
|
Dan and I leak checked TM2 and ITW primary vacuum vessel. It was found a 1X E-7 atm.cc/sec leak on top T flange seal between TM2 and dump module in first
time check. But it is not a repeatable leak. I checked the same spot and around area two more times with increased helium volume.It did not show up again.
The first response could be a helium drift to dry scroll pump. I will check it again later. The primar vacuum vessel on ITW and TM2 are leak free. |

|
| After ITW HV test is done, TM1 has been connected to ITW. Water signals are checked in electrical room. They are good. |
|
Friday, April 08, 2016, 08:48, David Wang, ITW, Standard Operation, , , ITW water signal interlock check.
|
I did a ITW water signals interlock check with ISAC opp. They are checked once a year before first beam on.
2016-04-13 Same test is done on ITE also. Everything is good. |
