Abstract :
Summary form only given, as follows. Flux-trap magnets based on high-temperature superconductors have been proposed for e-beam control elements. Applications could include accelerators, klystrons, and mm-wave amplifiers. We have constructed compact magnets using bulk YBCO crystals which exhibit fields of 0.5-0.8 Tesla at 77 K, and in excess of 1 T at 65 K. We have also developed techniques of field-charging the superconducting rings in-place. The characteristics of the materials and the assembled magnets are presented, and application to specific types of mm-wave tubes are discussed.
