k-space imaging on Ag(111) with the Momentum Microscope: kx-ky-Image sequence taken by changing of the binding energy, FOV in real space: 30µm, FOV in k-space: 3×1/Å, binding energy range: 18.2…- 0.5eV, 25meV energy steps, energy resolution: 100meV, excitation: 21.2eV VUV photons (FOCUS HIS13, fine focussed), acquisition time/image: changing from 5s to 25s to improve contrasts.

k-space imaging on Ag(111) with the Momentum Microscope: sequence of E-k cuts through the kx-ky-E image stack rotated by 360° in steps of 5° to each other. FOV in real space: 30µm, FOV in k-space: 3×1/Å, binding energy range: 18.2…- 0.5eV, 25meV energy steps, energy resolution: 100meV, sample: Ag(111), excitation: 21.2eV VUV photons (FOCUS HIS13, fine focussed), acquisition time/image: changing from 5s to 25s to improve contrasts. The parabolic shape of the energy dependent emission horizont is nicely seen.
