PM4 LowDosePES

This soft x-ray bending magnet beamline is equipped with a Plane Grating Monochromator operated in collimated light (collimated PGM). It has two permanent endstations, the reflectometer and the SURICAT (photoemission and x-ray absorption spectroscopy) which are in alternative operation.

The reflectometer station at this beamline is dedicated to the BESSY in-house R&D in optics development and at-wavelength metrology of (multilayer) optical elements.

Beamtime at this station is available by user-proposals or, at short-term request, by cooperation with our Institute for Nanometre Optics and Technology.
