[RASMB] in-house lamp cleaning

[Virgil Schirf]

Dear Avi,

Cleaning the xenon flash lamp is a relatively simple operation. There is a
user manual at http://www.uslims.uthscsa.edu click on AUC Manual which has
a section on lamp cleaning. We use toothpaste to clean the lamp; others
use pencil erasers. Keep the alignment of the lamp the same as it is
currently in. If you have a window in the monochromator shaft, that may
need to be removed and cleaned as well.

Best of luck,

Virgil
