35 period planar undulator, minimum gap 32 mm
Mirror 1: Flat, nickel-coated, 40 mrad grazing angle, water-cooled silicon, 12.95 m from the source.
Mirror 2: Toroid, 50 mrad grazing angle, major radii 100.6 m, minor radii 0.426 m, gold-coated, water-cooled silicon. Focused beam horizontally onto entrance slit with a magnification of 0.13 and focused vertically onto the exit slit with a magnification of 0.42. Located 17.8 m from the source
Monochromators: One fixed, spherical grating, 3.5 degree included angle, gold-coated with discrete water cooled entrance slits of 10, 25, 40, 70, 120, 200 microns and fixed vertical exit slit with slits sizes of 10, 25, 40,70, 120, 200 microns and variable size horizontal exit slit. Located 21.45 m from the source.
Order-Sorting Mirrors: 2 parallel quartz mirrors, vertically deflecting at approx. 3 degree grazing angle, resulting in approx. 1 mm vertical beam offset, used to preferentially absorb higher orders from the source. Located 26 m from the source.
6-Circle Soft X-ray diffractometer and Imaging endstation with zone plate focussing optics and in-vacuum CCD detector.

Computer System Hardware & Software
The X1A2 beamline is fully automated through the use of EPICS based on a mixed Linux/VME vxWorks platform. Diffractometer controls and data acquisition is through SPEC.
