Abstract

The “Klevafella” permanent magnet system uses a cladded design to produce a constant, longitudinal magnetic field in a compact, lightweight package. In this effort, the Klevafella design was adapted to the specific requirements of a linear beam microwave tube. Subsequently, a system was constructed to test the design. This system was operated with a 22 kV, 1.6 A beam tester and provided 98% beam transmission. The successful integration of the Klevafella design with this beam tester confirms that the Klevafella permanent magnet system is compatible with linear beam microwave tubes
