Highly coherent electron beam from a laser-triggered tungsten needle tip
Dominik Ehberger, Jakob Hammer, Max Eisele +4
We report on a quantitative measurement of the spatial coherence of electrons emitted from a sharp metal needle tip. We investigate the coherence in photoemission using near-ultrav…
A microwave chip-based beam splitter for low-energy guided electrons
Jakob Hammer, Sebastian Thomas, Philipp Weber +1
We demonstrate the splitting of a low-energy electron beam by means of a microwave pseudopotential formed above a planar chip substrate. Beam splitting arises from smoothly transfo…
A tip-based source of femtosecond electron pulses at 30keV
Johannes Hoffrogge, Jan-Paul Stein, Michael Krüger +5
We present a nano-scale photoelectron source, optimized towards ultrashort pulse durations and well-suited for time-resolved diffraction experiments. A tungsten tip, mounted in a s…
