|
UCx#19 has been removed from TM4 and UCx#20 installed.
UCx#19 still had water in it at pressure and sprayed when the VCR was undone. It was quickly re-tightened but not before significant water pooled
beside the main Mykroy standoff and table. Contacted Anders would suggested to soak it up with some wipes and continue, which I did. |

Wednesday, May 17, 2017, 08:31, David Wang, South Hot-Cell, Standard Operation, TM4, , Leak check on TM4 HS line at SHC
|
Chad and I finished leak check on HS line with UCx target installed on it. Base Leak rate:0.0X 10^-9 atm.cc/sec, Base pressure 0.0X 10 ^-4 torr.
Sprayed helium to VCR joints. No leak has been found . The line will be pressurized with helium at TCS.
Helium pressure test on TM4 HS line is done at TCS. BLR 0.0XE-9 atm.cc/sec. 70psi helium , 2 minutes. No response. The line is leak free. |

Wednesday, May 17, 2017, 08:35, David Wang, Conditioning Station, Standard Operation, TM4, , TCS turbo pumps was started yesterday
|
Anders started TCS turbo-pumps yesterday. The TCS and TM4 pumping down is good so far. I started TCS water pumps this morning for TCS water flow check.
2017-05-17 morning: Stopped the water pumps. The field around the TM4 is high because of spent target in SHC. The water flow measurement
will be delayed to this Friday. |

Thursday, May 18, 2017, 10:08, David Wang, Conditioning Station, Standard Operation, TM4, , TM4 TP1 at TCS
|
TM4 TP1 was found making some noise during operation this morning. The current draw was check then. It was 1.8 A which is higher than 1.0A normal range.
The pump body temperature was higher by hand feeling. But,1.0 hour later when checking again, everything on the pump goes back to normal. It is still fine
so far. I will watch on this pump closely. |

|
TM4 TP1 is replaced. TCS and TM4 was argon vented before the job.The job took about 30minutes. I started the all turbo pumps after job. All pumps
work fine. The TCS vacuum is good. |

|
The target was inspected by Chad and Anders. Photos are available on DocuShare.
It was noticed that the target tube heater terminals had lifted up from the insulator on the target assembly as seen in this Photo.
This has later been detemined to be from the assembly, where additional clearance was required and achieved by installing |
