摘要： Electron gun with band-shaped beams that includes a vacuum chamber extend in a longitudinal direction, a beam window running in the longitudinal direction along the vacuum chamber, and a cathode control-electrode system positioned within the vacuum chamber in the longitudinal direction. The cathode control-electrode system includes at least one substantially straight cathode positioned substantially parallel to a longitudinal axis of the cathode control-electrode system and the at least one substantially straight cathode has bulges formed at defined distances. The bulges are shaped to produce a substantially homogeneous current density distribution along the at least one substantially straight cathode and support units are located in the cathode control-electrode system to correspond with the bulges. The bulges are removably couplable to the support units.
