David Wang | Conditioning Station | Development | TM2 | | TM2 gas line reconfiguration on the module top. |
Reconfigured TM2 gas line on the module top. It matches with the febiad gas line we are using on service tray now. Facing the module, both of them should be that right side line of two SST lines on feed-through. The gas line on TM2 was leak checked with a blind cap installed on service tray side and LD connected on module top this Tuesday. It is leak free with helium spray on the top of module and service tray. |

David Wang | Conditioning Station | Standard Operation | TM2 | | Helium pressure test on TM2 water llines at TCS. |
The helium pressure test on HS line is done at TCS this morning. I got the same result as last time when we helium pressure it it with first target in April. The leak rate on this line is 1.8 XE-7atm.cc/sec. So, we know this leak is mostly on the line, but not on the VCR joints connecting the target. See attachment for last time(April) checking e-log. The leak could be from water block which is same as other lines. I do not think this leak rate will affect the operation.
The attachment can not be opened for some reasons. Please check TM2 leak check 2017-03-13 e- log for last time test result and comment. |

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.
2017-05-19,morning. The TM4 TP1 stopped running last night. I tried to start it this morning. But, It can't pass 6KRMP even. I think we have to replace it. E- fault will be issued as well. |

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. |

chad fisher | South Hot-Cell | Standard Operation | TM4 | UC#20 | UC#20 Installed |
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.
New target fasteners including high current. High current fasteners torqued to 130 in lbs. |
