|
Ta#56 has been moved from the south hot cell to the storage vault. It was placed in pail#169 and place in slot 2C of the vault. Also the vault is now full with 24 spent targets and can no longer accept any new targets. See the attached PDF for further details. |

Thursday, August 30, 2018, 07:46, David Wang, Conditioning Station, Standard Operation, TM4, , TM4 HS line leak check at TCS and SHC.
|
Chad and I leak checked TM4 HS line after UCx 24 is installed. No leak at 5xE-9atm.cc/sec. Today, I did helium pressure test on HS line at TCS. No leak at 70 psi helium 0.0xE-9 atm.cc/sec. |
|

|
TM4 has been connected to TCS. vacuum system and water system are started. Everything looks fine. |

Tuesday, August 14, 2018, 10:27, Travis Cave, ITW, Standard Operation, TM2, UC#23, Module move
|
Both the West Entrance and TM#2 with UC#23 have been moved back into their places in the west target station. The Entrance module move wasn't completely smooth as it did suffer a little bumpiness when the shield plug part was installed, I was lifted back out again and no visible damage was observed on the delicate items. |

|
The west entrance module has been moved from the west target station to the south hot cell, for a bellows replacement. |

Thursday, August 02, 2018, 14:12, Travis Cave, Spent Target Vault, Standard Operation, , Nb#8, Spent Target Move
|
The spent Nb#8 target was moved from the south hot cell to the spent target vault. It was placed in pail #168 and place in spot 2A in the vault. See the attached pdf for vault details. |

Thursday, August 02, 2018, 07:57, David Wang, Conditioning Station, Standard Operation, , , Leak check on TM2 UCx #23 @ TCS and SHC.
|
I did a helium pressure test on TM2 HS line at TCS. At 70psi helium, the leak rate is 2.5 xE-7 atm.cc/sec. I think this is the number that close to result before which is 1.7xE-9 atm.cc/sec. WE know there is a small leak on this water block seal. Chad and I did helium spray check yesterday at SHC. It was good at bottom scale. No much worry on this low E-7 range leak. |

Wednesday, August 01, 2018, 15:12, Anders Mjos, South Hot-Cell, Standard Operation, TM2, UC#23, Target mounted - water leak on HS line
|
The heat shield water lines were not purged ahead of target exchange in the hot cell. This resulted in water leaking onto the new target assembly (heat shield) when the cooling lines were opened at top and bottom (for connecting leak detector). Excess water was wiped up with paper towels. |

Wednesday, August 01, 2018, 09:47, Isaac Earle, North Hot-Cell, Development, , , NHC diagnostic signals and control panel tested
|
On July 30th the NHC diagnostic signals were tested:
- 9 pin CPC: a shorting plug was installed on the hot side - continuity check results were as expected
- 4 pin CPCs: snake camera installed in both hot side connectors with portable monitor on cold side - both connectors worked as expected
- USB: laptop connected on hot side, USB mouse connected on cold side - worked as expected
- Ethernet: laptop connected on hot side, cold side connected to building ethernet port - connection to network worked as expected
- SHV: a shunt was installed on the hot side - a short circuit was measured from the cold side as expected
with no shunt installed the line was Megger tested: 1.63 G-ohms recorded @ 1000V
The control panel switches for the in-cell receptacles were also tested. Each switch (a - d) worked as expected.
On July 31st the gas supply solenoid valves were tested. 60psi air was hooked to each solenoid inlet. With the valve closed there was no air flow. When each push-button or switch was activated air flow was observed through the correct solenoid. |

|
Yesterday the spent UC#22 target was moved from the south hot cell to the spent target vault. It was placed in pail #167 and placed in spot 4A see attached PDF for details. |

Wednesday, July 25, 2018, 13:21, Anders Mjos, ITW, Repair, TM2, Nb#8, Leak check of ITW
|
ITW Entrance Module was leak checked yesterday with the support of Vacuum Group (Dimo & Edi). The leak detector was connected to primary backing vacuum line. A leak response was found near the bellow for the beam profile monitor on top of the Entrance Module. It could be confirmed today by actuating the monitor, that the leak was indeed at that location. The plan is to move the TM and Entrance Module out for target exchange and repair, respectively. Drawings of the device available on ITA0200and ITA5128 |
