Beamline 9.3.1 Overview
Beamline 9.3.1 is a bend-magnet beamline which provides high-resolution x-ray beams for electron, ion, and x-ray spectroscopy measurements in atomic, molecular, and materials science.
The beamline is built around a double Si (1,1,1) crystal monochromator with a 2.32 to 5.6 keV energy range. This range includes the K-edges of sulfur and chlorine.
The optical design includes two identical, but oppositely defecting, toroidal mirrors positioned symmetrically before and after the monochromator. This approach yields two benefits: high resolution by providing parallel x-rays for diffraction by the Si crystals, and a small beam spot by means of 1:1 focusing of the storage ring source with a minimum of aberrations.
The minimum beam size is better than 0.7 x 1.0 mm, and the position stability is less than 10 micron vertically and 25 microns horizontally. The beamline delivers over 1.3 × 1011 photons/s with a resolving power near 7000.
