Friday, March 04, 2016, 12:34, 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. |

Tuesday, June 07, 2016, 11:42, 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. |
