[Dsg-rich] Reflectivity test station's monochomator not working

[Amrit Yegneswaran]

marco, 
i do hope they can. 
it would be wonderful 
maybe nick has a spare monochromator 

but from past experience, i would say its wishful thinking. 
last time peter had to fix the problem. 

maybe, tonight i should give the monochromator a couple of whacks! 
remember murphy's law "If it jams - force it. If it breaks, it needed replacing anyway."!!!

Hi Tyler, 
You could contact Yuri or Nick first, perhaps it is a known problem and 
they know how to solve it.
