Abstract

In the modified SX-700 monochromator installed at beam line I411, the focusing before the exit slit is achieved by a plane elliptical mirror. Like in the original SX-700 design, the resolution is mainly limited by the slope errors of the focusing mirror. A simple method to improve the resolution is to replace the focusing mirror by one with smaller slope errors. The effects of replacing the refocusing mirror by similar but more accurate in shape are studied both by carrying out ray tracing simulations and by analytical approach. Also the effect of replacing the grating was studied. (c) 2006 Elsevier Ltd. All rights reserved.
