Abstract :
Flux-trap magnets based on high-temperature superconductors were studied for their potential as electron-beam control elements. Applications could include accelerators, klystrons, and MM-wave amplifiers. The authors have constructed compact magnets using bulk YBCO crystals that exhibit axial fields of 1.0-1.2 T at operating temperatures from 65 K to 77 K. Transverse fields and field stability have also been measured. Finally, methods and mechanisms involved in pulse-charging the superconducting rings are discussed.
