Apparatus for generating electron radiation and 3D printing apparatus
11433609 · 2022-09-06 ·

An apparatus for generating electron radiation comprises a wire-shaped hot cathode that is much more extensive in a longitudinal direction than in a transverse direction. Electron radiation emerges from the hot cathode that, due to the elongated shape of the hot cathode, exhibits an elongated, line-shaped cross section perpendicular to its direction of propagation, where the extension in longitudinal direction of the line is significantly greater than in transverse direction of the line. The apparatus further comprises a cathode electrode and an anode. A voltage for accelerating the electrons emitted from the hot cathode is applied between the cathode electrode and the anode. The hot cathode is arranged to be spaced apart from the cathode electrode such that electrons that are accelerated to the anode are emitted from the hot cathode in each of the transverse directions.
