Hello everyone,

        In the process of coupling one of our diffractometers with a rotating anode 
X-ray source I find I need to buy a new monochromator crystal, and collimation slits 
controllable in size from 1mm to 10 micron.  I am asking the pooled experience 
represented here for any suggestions on where to order these from.  I have a couple of 
leads, but would like to hear any further suggestions.  Also, remember, just a crystal 
cut to a certain angle is typically not sufficient and efforts to increase mosaic 
spread must be taken in order to increase reflectivity.  I am also sending a similar 
request to sci.techniques.xtallography, so, sorry if you're reading this in duplicate.

        Thanks,  AlexY
