|
Two minor chips in the main 60 kV insulators on the source tray was inspected today by Anders, Tom and Aurelia. The chips are small enough that
they should not be a problem. See photos for details. |

Thursday, October 19, 2017, 10:11, David Wang, Conditioning Station, Standard Operation, TM4, , Leak check on TM4 HS line at SHC and TCS.
|
Chad and I leak checked TM4 HS line after new target is installed yesterday. No leak has been found. Also, I helium pressurized the HS line at TCS this
morning. TM4 HS line is good on this test. The TM4 gas line configuration on TM4 top is leak check as well. No problem. |

|
Source tray is complete for brazing, gas line bracket is currently missing but can be made in parallel with tube bending operations.
Source tray water lines to be fabricated according to ITA6144 drawing set.
- Alignment between target mounting plate and steerer cone is holding within .002" |

Thursday, October 12, 2017, 08:48, Travis Cave, Spent Target Vault, Standard Operation, , , Field measurements of the old source trays
|
Field measurements were taken of the old source trays. The old TM#2 source tray had a minimum field value of 0.50 mSv/hr and a maximum of 1.18
mSv/hr through 360 deg of rotation. The box was rotated around three times and put back in the vault. TM#1 old source tray was also removed and measured
as well the field values for it were a minimum of 0.52 mSv/hr and a maximum of 1.15 mSv/hr through 360 deg of rotation. The box was rotated around three |

|
TCS cooling polyurethane lines have been re-routed to solve to HV sparking issue on old configuration between lines and bais plate. New re-routed
system is tested to 70KV without spark. No leak has been found on new lines after the test.
ECO 4369, drawings and models IRH1715, IRH1716 have been issued and released for this job. Drawings and Models are located in PDM-ISAC1 -TCS polyurethane |

Friday, October 06, 2017, 11:21, Isaac Earle, North Hot-Cell, Development, , , ISAC-1 active sump drain pipe modified
|
The 4" PVC drain line in the ISAC-1 active sump was modified so that the drain pipe terminates below the low level water line of the automatic pump-out
system. This will prevent backflow of sump gasses into the SHC, NHC, or TCS space if the air pressure in any of those rooms are lower than the sump
air pressure. The details of the modification were specified by Mechanical Services Group, and the work was done by Paul Jensen. This system |

Friday, October 06, 2017, 11:12, Isaac Earle, North Hot-Cell, Development, , , NHC module port shield block and TCS vessel shield block installed
|
The NHC module port shield block (IRH1645) and the TCS vessel shield block (IRH1646) were installed yesterday in the target hall according to assembly
drawing IRH1652. No issues were encountered during installation. Vacuum was pulled on the TCS and a leak check was performed on the shield:
no leaks found. |

|
Due to problems with the regulating valve WPV1, the VFD (Variable Frequency Drive) for the pump has been programmed to do a slow (2 min) ramp up.
WPV1 has been bypassed and left fully opened. Work was done by Dave Morris |

Thursday, September 28, 2017, 10:50, David Wang, Conditioning Station, Standard Operation, TM2, , Helium pressure test on TM2 window and HS water lines at TCS.
|
I did helium pressure test on TM2 containment box window and HS line at TCS. @ 70psi helium for 3 minutes, HS:2.2XE-7 atm.cc/sec., Window:1.2XE-7
atm.cc/sec. There is no change on HS. But LR on window is bigger than before that was in E -9atm.cc/sec range. |
