During the opening the vacuum group and company regenerated one of the
ion pumps on the DP station and separated the controls in order to give
better diagnostics and help the vacuum.
The Compton from the laser enclosure to the DP station was re leak
checked and no leaks found.
During the operational check out after the leak check a bad Ion Pack
(controller) was found and replaced. This should help the vacuum which
was -8 range or better when we left the Hall.
