Note,

We are prepping for BT accumulation measurements and therefore Kyle is mounting and commissioning an RGA at the Beam Tube pump port which houses PT124. Reference Work permit #4508.

Expect PT 124 to range from 1E-9 to 1 E-6 torr while this work takes place. For the actual accumulation the mid station gate valve will also be closed and PT 124 as well as PT243 will begin to rise. The accumulation period may be as long as 48 hours.
