The miniXS Homepage
The development of 'miniature x-ray spectrometers' (miniXS) by Seidler's group at the University of Washington is based on the development of a new family of short working distance x-ray optics. [1]  The first such instrument was tested in August 2008, and is shown in the photograph.  The top panel is the SWD optic, which consists of several 4 x 4 mm2 Si 110 crystals mounted on a lens with a 1-inch radius of curvature.  The bottom panel shows the raw data from an x-ray sensitive camera due to a brief exposure to the  x-ray emission from Dy metal.

These spectrometers are inexpensive, have very large collection angles, and can be adapted to a wide range of possible experimental energy ranges and sample environments. [2]  Work is ongoing to adapt miniXS to studies of battery electrodes, high pressure cells, laser/x-ray pump/probe experiments, and cryostats.
