[RASMB] Broken XLA Mono

[John Burgner]

John,

I had the same thing happen with our old XLA.  I was able gently shake the
monochromator while holding it in a horizontal  position and get the filter
out of the light path.  If you can locate Skip Perry, who was a long-time
Beckman service  man, he might be able to help out.

Dear AUC Techies 

   I picked up the Monochromator out of it's box and I heard a glass like
tinkling inside near the order filter. The order filter only moves a small
amount and won't go either way to it's normal stop. It's apparent to me that
something is broken. No one in the lab knows how this happened. The last
logged user got good results. It now will not pass any energy.

    The PI called Beckman and they offered to replace it for an exchange
price of $16,000.00. 

    Does anyone have experience repairing/disassembling and reassembling one
of these? Any hints, tips, or suggestions? 

 

John Gunther
