Power surge or failure resulted in loss of vacuum and gun operations.  system tripped
into 'save itself' shutdown mode and gun isolated but the chamber came up to ~ 500 mT
range.
Expect to be able recover and bring back the gun to normal values.  Four to five hours
to reach suitable vacuum at best.
all User access and use suspended through 2200 hours this evening.  I may take up to
24 hours for beam conditions to stabilize.  Full update at 9:30 AM Thursday.  JWC
