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 approximately 5.2 keVenergy range. This range includes the K-edges of sulfur and chlorine. The flux begins to drop off dramatically over 4.8 keV.
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.
