  577   Monday, April 10, 2017, 15:12 Anders Mjos      Problems/SolutionsVacuum leak on front door

The vacuum behaved erratic over night with excursion up into the mid 10^-6 Torr range. To investigate the chamber was vented. With the doors open, the o-rings and sealing surfaces were cleaned. When pumping down again a vacuum leak could be heard at the front door by the lock. The chamber was vented again twice, finally the two o-rings were swapped. This removed the large leak. The door is prevented from contacting the box at the lock, which is likely the source of the leak.

 Target Test (Fully Cleaned vs Crystal Clean only).

For all tests:

-Start Turbo pumps & Ion gauge as soon as available on ISAC TEST STAND VACUUM Screen.

- Ensure previous test turbos are off by 8:15 and started venting by 9:15am to meet timeline.

-Start Roughing by 10:10am +/- 1 minute.

-TGHT / TBHT ramping starts @ 8:30am. 2A per min to 580A / 200A

ALL START TIMES MUST BE CONSISTENT.
