  Beamline I22 at Diamond Light Source is dedicated to the study of soft matter
systems from both biological and materials science. The beamline can operate in
the range 3.7 keV to 22 keV for transmission SAXS and 14 keV to 20 keV for
microfocus SAXS with beamsizes 240 x 60 {\mu}m$^{2}$ spot [Full width half
maximum (FWHM) Horizontal (H) x Vertical (V)] at sample for the main beamline,
and approximately 10 x 10 {\mu}m$^{2}$ for the dedicated microfocussing
platform. There is a versatile sample platform for accommodating a range of
facility, and user developed, sample environments. The high brilliance of the
insertion device source on I22 allows structural investigation of materials
under extreme environments (for example fluid flow at high pressures and
temperatures). I22 provides reliable access to millisecond timescales,
essential to understanding kinetic processes such as early folding events in
proteins or structural evolution in polymers and colloids.
