| 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. Contact Jerry Seidler for more information. |
