Abstract: | Resolution and intensity behaviour of the spherical analyzer are mainly determined by the entrance parameters (aperture angle
2α
m
, relative width of the entrance slita/r
0) and by the relative width of the exit slitb/r
0. The mutual relation of these parameteres can be so optimized that independent of the required resolution the quantities
étendue or luminosity of the spherical analyzer attain a maximum. |
