Figure 6
Vertical acceptance of the three spectrometer designs, (left-hand column) the elliptical cylinder, (second column) the toroid and (third column) the sagittal collimating diaboloid. Each row corresponds to a particular energy, (top) 540 eV, (middle) 350 eV and (bottom) 930 eV. The three plots starting from the left-hand side on each row show the evolution of the vertical image profile as the vertical acceptance is increased up to 22.5 mrad (curves offset for clarity). The right-hand plots show the resolving power determined by the vertical image profile as a function of the vertical acceptance. The ray-tracing images are convolved with the detector spatial resolution. The horizontal acceptance is set to 0.5 mrad, narrow enough that horizontal aberrations are negligible and do not affect the energy resolution.
