Abstract
The emitter includes recipients expanded in a longitudinal direction, with a beam emission window running in the longitudinal direction of the recipients. A cathode control electrode system is arranged in the recipient in its longitudinal direction. In the cathode control electrode system is arranged at least one wire cathode running parallel to the longitudinal axis of the control electrode system. The wire cathode (12) has bends (16) at defined distances. Support elements (8) are arranged at equal distances in the cathode control electrode system (3). The bends (16) are alternately connected to the support elements (8). The bends (16) are formed such that an approximately homogenous current density distribution in the direction of the beam window (2) is obtained over the whole length of the cathode (12). ADVANTAGE - Can be realised for any desired radiation width. Requires no tension element for cathode. Allows cathode to be easily exchanged. Has space saving construction. Provides l inear homogenous electron beam.
