PM4
Soft X-ray dipole variable polarisation with PGM and MHz Chopper for LowDosePES
This soft x-ray bending magnet beamline is equipped with a Plane Grating Monochromator operated in collimated light (collimated PGM) and with a MHz Chopper System to create single bunch on demand for the ArTOF Low Dose PES end-station.
