Schematic view of the spin-filtered ToF momentum microscope, consisting of He-cooled sample stage, imaging electron optics, two drift sections with delay-line detectors for spin-integral (horizontal branch, DLD 1) and spin-filtered (vertical branch, DLD 2) imaging. The W(001) spin-filter crystal is located in a field free space and can be inserted and retracted.
