{Gerardo, Chandra}

After regenerating the three corner station NEG pumps on Tuesday, we observed the local housing pressures at NEG 1,2,3 for a couple of days before valving into main volume. While valving in (waiting 10 minutes between each NEG), we scanned the RGA and observed no noticeable change in AMU peaks. The total pressure decreased slightly.

Time stamps of each for RGA correlation (all local times): 

1. 2:45pm valved in NEG1
2. 2:56pm valved in NEG2
3. 3:06pm valved in NEG3

Gerardo noticed gappy flanges on the BT side of the NEG isolation gate valves and Kyle does not recall spraying He directly at these on Tuesday when we "fire hose" leak checked the corner. These three units are near the RGA, where we observed the most notable increase in He signal while leak checking on Tuesday, so we would like to leak check these again.
