Abstract : The patent describes a method of and means for generating a magnetic field in the interaction area of a cross-field device wherein the permanent magnet is positioned outside of the vacuum of the device. Samarium cobalt magnet material is placed inside the cathode or sole of the device and end caps made from high-permeability material are used for pole pieces. Since the samarium cobalt is at end shield potential no additional air gap is required.
