PATENT APPLICATION For PERMANENT MAGNET STRUCTURE FOR CROSSED-FIELD TUBES By Alfred W. Cook and Thomas H. Schultz ABSTRACT A permanent magnet structure particularly beneficial for generating the interaction field in coaxial, crossed field electron tubes is designed such that the normal iron flux return path is not required. Substantial reduction in weight results. A further benefit is that a magnetion interaction structure including the magnets may be built as a unit replaceable in the field in a stabilizing cavity structure. Since the cavity structure contains no iron the magnets are not demagnetized in the replacement process and there are no mechanical mounting problems caused by magnetic forces.
