Abstract

The x-ray monochromator SX700 High Flux design is based on the successful basic SX700 system which is installed in various beam lines. It consists of a rotatable plane tilting mirror, a rotatable plane grating, and a fixed ellipsoidal focusing mirror. By using two different gratings, the SX700 covers the energy range from 5 eV to 2800 eV. Together with the control software it is possible to move the tilting mirror together with the rotating grating continuously in such a way that a fixed source focus is achieved over a wide energy range (from 38 eV to 2800 eV for 1220 l/mm and from 11.4 eV to 860 eV for 366 l/mm). The most recent software update now includes any user defined angle relation between mirror and grating. To withstand the high heat loads of synchrotron beams without any compromise in optical performance, the SX700 monochromator was upgraded. This is achieved by a proper material selection for the optical components (plane mirror and grating) and by the installation of a respective cooling system for these components. In this paper the development of the chosen design solution and first beam line results are reported.
