 Tuesday, May 10, 2016, 13:54, David Wang, South Hot-Cell, Standard Operation, TM2, , SHC, TM2 leak check on window line and HS line.
|
Chad and I leak checked the TM2 HS and window lines after new target installation. The window line was very easy pumped down on LD. But, The HS line only could pumped to 2-3 torr at first. Chad changed the VCR gaskets on HS line(target). It solved the problem. The LD could pumped both of Window and HS lines to the bottom scale. Chad sprayed lots helium around the VCR joints. No leak has been found. WE will do helium pressurizing test on them at TCS. |

Friday, May 13, 2016, 10:08, David Wang, Conditioning Station, Standard Operation, TM2, , Helium pressure test on TM2 HS and window line at CS with new Lp Ta target
|
These two lines are passed helium pressure test this morning. The LD base leak rate 0.0 X E-9 atm.cc/sec. The base pressure 0.0 X E-4 torr. Helium pressure 70 psi. applied helium to both line for 5minutes each. No response on LD during the test. |
|
