A soft X-ray plane grating monochromator installed at Louisiana State University's Center for Advanced Microstructures and Devices has been characterized and the first experimental results obtained. The monochromator is a modified SX-700 design which uses a moveable pre-mirror to allow the instrument to remain in focus over an energy range of 8 to 1200 eV. Since the pre-mirror motion is independent of the grating rotation, the monochromator can be used in three different modes: maximum resolution (fixed focus), maximum throughput, and maximum higher-order rejection. Absolute intensity measurements for all orders are reported for two fixed angles of the pre-mirror and for the fixed-focus mode. Results from the first experiments using the monochromator are reported. © 1994.
