I believe the SGM beamline (11ID-1) at the Canadian Light Source also
works in this energy range.

Data from X15B comes off the beamline in the form of a strange binary
file. Athena's capability to read these files is implemented in the
form of a file type plugin. Here is the reelavent section from the
Scroll down to the description of the the plugin registry for an
explanation of how to get started. In short, you will want to turn on
the X15B plugin. Once you have done that, Athena should recognize X15B
binary files and convert it into a readable form for import.

The 1 - 2 keV range is a really tough energy range. X15B was filling a
niche at NSLS. To my knowledge -- and after a quick peak at the NSLS
beamline guide -- there isn't another beamline at NSLS offering photons
for XAS in the energy range. None of the UV ring spectroscopy beamlines
advertise an energy range above 1200 eV.
There are some other options if you are willing to look farther afield
than NSLS. The XAS beamline at CAMD is one option. I believe that
there are beamlines at the ALS that can do XAS in that energy range.
Examples from even farther afield would inlcude the Lucia beamline at
Soleil and beamline 8 at the Thai synchrotron.
Perhaps some of the folks on this mailing list can suggest some other
options for that energy range.
