Conversion of the oldest XAFS station at the first dedicated SR source to a state-of-the-art XAFS facility

Abstract

Station 7.1 was the first XAFS station to operate at the Synchrotron Radiation Source (SRS) starting in 1981. A major upgrade of 7.1 has been taking place aimed towards a multi-dimensional XAFS and single crystal facility for 3d elements (Ca to Zn). The optical upgrade included a collimating mirror and QuEXAFS monochromator, also a highly compact and rapid count-rate multi-element solid state detector has been designed, built and recently commissioned. A stopped-flow system is commissioned and a diffractometer stage is planned. The necessary analytical tools for 3D XAFS refinement using crystallographic data as the starting 3D model have been developed for solution XAFS.
