Beamline description

Beamline

Zone plate focusing optics utilizes only coherent flux of the beam determined by the central source brightness. Taking into account relatively low photoemission cross sections SPEM has become possible thanks to appearance of high brightness 3d generation synchrotron radiation sources such as ELETTRA. Accordingly, prefocusing and monochromator optics were designed with the scope to convey the beam to the exit slit of the monochromator and not to destroy its spatial coherence.
