Figure 3
Schematic of the energy–position correlation in the six different geometries of Fig. 2. Right-hand line shapes are projections of the resolution function of each detector element. E − E0: relative energy, yd: detector y-position; p: detector pixel size; 2c: image size of the small cube crystal. 2c′: demagnified image size. The temperature gradient of the analyzer reduces the aberration [(III), (VI)]. |
