[RASMB] Broken XLA Mono

[John Gunther]

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
