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 20-500 K by resistive heating; up to ~1200 / 1700 K long-term / flashing by electron bombardment; direct current heating also possible
Pressure range Base pressure within <5x10^-10 and 3x10^-9 mbar. With possibility to dose selected gases.
