many of the problems encountered -- but not all the problems reported -- have been traced to failure of the cooling water recirculation pump to the lens, vacuum control, card and EHT power supply on the RAITH system.
Will be troubleshooting flow and pressure and arranging for yet another NESLAB recirculation unit later this afternoon.  Raiths ervice has been contacted and a field service person will be on site either very late tonight or first thing tomorrow morning. (Tuesday)  
System is off line for all users until repairs can be effected and the system re-qualified for EBL performance.
Good Day,
JWC
