Figure 7
The relation of energy shift and detector vertical position (yd) in the case d = 10 mm. Left-hand plots: energy–position correlation with selected analyzer positions xa = 0, 20, 30 and 45 mm. The gray vertical lines correspond to a detector pixel size of 0.172 mm. Right-hand plots: geometric energy resolution obtained by ray-tracing calculations with DC. Slope error and source-size effect are included (see the main text). The thick lines are dispersion-corrected data. |
