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.


Station data
Temperature range 10-500K. Heating up to 1200 K and flashing up to 1700 K will be possible with the replacement of the current manipulator, planned for 2022.
Pressure range Base pressure within <5x10^-10 and 3x10^-9 mbar. With possibility to dose selected gases.
