Resolving Power and Flux for both EMIL beamlines

Resolving Power and Flux for both EMIL beamlines

A toroidal mirror M1 collimates (vertically) and focusses (horizontally) the UE48 beam onto the exit slit. The radiation is dispersed by a plane grating monochromator equipped with two blazed gratings (400 and 800 l/mm). A switching mirror unit M3 with two cylindrical mirrors deflects the beam to the endstations SISSY-I and SISSY-II or to another upcoming PEEM station (not shown). Alternatively the mirrors are retracted and an additional cylindrical mirror provides the radiation for the CAT experiment. Two ellipsoidal mirrors in the switching mirror unit M4 refocus the exit slit stigmatically to either the SISSY-I or SISSY-II endstation, and a toroidal mirror refocuses the beam to the CAT endstation.
