[Ifeffit] Capillaries

[Paul Fons]

Continuing in the vein of marginally relevant questions (you need to 
take data before you can analyze it with horae!), I have yet another 
question.  To make life more exciting, I would like to take a 4 m in 
vacuum undulator beamline that has a focussing mirror with a 250x600 
micron spot size and focus down as much of the beam as I can to 
dimensions on the order of a micron (or a little bit bigger) using a 
monocapillary.  I would then like to do microexafs with this setup.  
The brilliance of the undulator is about 5x10^15 in the range I am 
interested in (about 11-12 keV).  Has anyone had any experience with 
this sort of focussing and might you recommend a company or spec to 
try?  Thanks in advance.
