Subject: Shutdown raith SNF 2012-09-05 10:04:22: Clicking noise from Beam blank controller / high speed pattern processor
From: kcbalram@snf.stanford.edu

When the beam is turned on, there is a clicking noise from somewhere in the beam blank
controller / high speed pattern processor and the stage position (X,Y coordinates)is
fluctuating wildly. 
Loading / unloading stops the noise but it comes back once the beam is turned on again.
I tried restarting the system but that did not work. 
I haven't seen this problem before. I am not sure the system is usable right now, hence
I am shutting it down and reporting the problem to Raith field service.
Best,
Krishna
