Good Afternoon:

*RAITH STATUS:  DOWN AND OFF LINE TO USERS...*

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.  Raith service has been 
contacted and a field service person will be on site, either very late 
tonight or,  first thing tomorrow morning. (Tuesday AM) 

System is off line for all users until repairs can be effected and the 
system re-qualified for EBL performance.

Good Day,

JWC
