A stuck shutter will not cause us an exposure problem at LBL for several 
reasons, however - I was led to beleive that most supper shutters had a 
shutter closed sense switch!!??  If this is not so - I am concerned!  I 
think we will look into that.

In any event there is still the "flag" and we have _NO_ lead foil wrapped 
around our machines - as I have seen so very prevalent at many other 
institutions.  We simply do not allow it.
