multiple module and sub-system failures to stage and vacuum control on the RAITH 150.
 SYSTEM IS DOWN for today.
Loss of Laser Interferometer control through IEEE-488 interface card.
Gun failure and now the gun is down waiting suitable vacuum  to chamber and gun section.

Loss of T axis coordinates on the Load Lock transfer arm.(Stage coder signals and Virtual
control module errors)
Shutting down the system and will perform a yellow button reset of stage and vacuum
controllers.
Will need to pump to suitable vacuum for further testing to continue.
Good grief!
