David Wang | ITE | Standard Operation | TM4 | | TM4 ITE annual leak check |
Dan and I finished TM4 and ITE annual leak check on primary and secondary vacuum vessel. We found one leak on a KF25 blank off which is located on the top of the service cap. It is a low E-7 atm.cc/sec range leak. But, it is very close to turbo-pumps so ITE IG1 and other gauges are not affected by it very much. It is an easy fix. TheKF -25 center ring on the blank off will be replaced after vent . It be will leak checked again at CS after replacement. That is only leak we found on TM4 and ITE primary and secondary vessel air to vaccum leak check.
Dan and I also finished the helium pressure test on all TM4 using water circuits. 70 psi helium. base LR 0.0xE-9 atm.cc/sec. All of them are leak free. No any response has been found on leak detector during test. |

David Wang | South Hot-Cell | Standard Operation | TM4 | Ta#47 | electrical check on TM4 with old Ta target at SHC. |
I did an electrical check on TM4 with the old target still installed. The number is a little bit low on 500V mega check between chassis and 60KVbias which is 146Mohm. Others are good. See attachment
I wrote all OL to 0 in attachment 1 ohmmeter check. Please See attachment 2 for correction. |

David Wang | Conditioning Station | Standard Operation | TM4 | UC#16 | TM4 UCx16 electrical check and leak check at SHC |
Chad and I finished the TM4 UCx6 electrical check and leak check at SHC. Leak check result on HS line is good. There is a dead short between "Z" repellor and HS during the first time electrical check. The dead short disappeared after re- installation of UCx 14 target onto TM4. See attachment
Anders and I did another electrical check on TM4 at TCS under vacuum. See attachment 2 |
