[Sneap] Interesting Problem -- posted for Tom Miller at Purdue

>Hi,
The ANU accelerator tube changes about a range during pump out and gas up.
We have leak chased repeatedly over the years and still can't explain it.
We have wire gaskets and the column is independent of vessel growth due to
pressure so it is very puzzling.
Maybe when we have our old RGA running again then we can look for gas peaks.
Still wondering for now.
Cheers, Al
