A Simple Analytical Approach to Describe a Beam Conditioning System

Abstract:

A simple analytical approach is given to calculate the performance of parabolic mirrors for various wavelengths. Expressions are given for the efficiency of the parabolic mirror system and insertion gain. As examples, parameters for some mirrors for CuKα and MoKα radiation are calculated.

Variation of Insertion Gain as a function of slit size for W/Si mirrors (dashed line) and Ni/C mirrors (Solid Line). For W/Si, the average rocking curve width was assumed to be 3. 5 arcmin and the average reflectivity was 0. 72. For Ni/C, the average rocking curve width was 1. 7 arcmin and the average reflectivity was 0. 8. The lengths of the mirrors were 40mm. The source dimensions are 0. 04mm x 8mm. The vertical slit size is 10mm.
