Friday, July 26, 2019, 11:41, David Wang, South Hot-Cell, Standard Operation, TM4, , TM4 with spare target electrical check and leak check.
|
Electrical check on TM4 with spare test target. PQ is still shorted to RU. But, The short between 60KV bias and PQRU which we found last time is gone. Target to PQRU at 250V mega measurement: 22.08 M. All conductivity between ABCD are about 5.0 m ohm which are good. All other ohm meter and Mega measurements are OL. Helium spray leak check on HS target VCR fittings is passed. Two blank offs are installed on source tray window cool lines. They passed leak checked at SHC as well. |

Thursday, March 14, 2013, 07:18, David Wang, South Hot-Cell, Standard Operation, TM4, , TM4 window cooling line leak check
|
It took a long time(more than 1 hour) to pump down the TM4 window cooling line during leak check time. The base leak rate could only be pumped to 5.8xE-9 atm.cc/sec.Base pressure is 0.0xE-4 torr which is bottom reading. Chad and i did the leak check at this base leak rate .No leak had been found. The window cooling line is leak tight at this stage. A pressure helium test will be fulfilled in conditioning station on this cooling line later. |

|
LD base leak rate, 0.0Xe-9atm.cc/sec. Helium pressure, 70psi. 5 minutes each circuit. No response on all water line except containment box window which has a VCR leak issue now. Window line leak rate, 2.3Xe-4 atm.cc/sec. |
