Abstract
A non-cryogenic electro-permanent magnet for use in a gyrotron comprises a plurality of toroidal-shaped sets of electromagnet coils and a plurality of toroidal-shaped permanent magnets, each permanent magnet comprising a plurality of arc segment blocks. Each set of the coils is separated from an adjacent set of the coils by one or more of the permanent magnets disposed between the adjacent sets of coils, such that the coils and the permanent magnets are arranged concentrically to form an open central bore. A combination of magnetic fields in the permanent magnets and magnetic fields in the coils generates a substantially uniform axial magnetic field in the bore.
