Due to high vacuum a leak check will be done on the system.

Thursday, July 19, 2012, 09:00 : Base leak rate 4E-9 atm-cc/sec

Thursday, July 19, 2012, 09:07: Leak detected on side door. Mid 1E-8 range.

Thursday, July 19, 2012, 09:08: Leak detected on front door. Mid 1E-6 range. Main leak left or bottom side.

Thursday, July 19, 2012, 09:20: Leak on side door could not be reproduced. Previous response possibly due to  "cross-talk" with front door.

 Thursday, July 19, 2012, 11:29: Wiped both o-rings, grooves and sealing faces with kimwipes. Removed black and brown residues.
