摘要：

The TE22, (6) 1 MW gyrotron operated at Forschungszentrum Karlsruhe (FZK) at frequencies between 114 and 166 GHz has been investigated with respect to the fast-frequency tunability in the frequency range from 132 to 147 GHz, For that purpose, the gyrotron has been equipped with a special hybrid-magnet system consisting of the superconducting (sc) magnets in the cryostat and additional normalconducting (nc) copper magnets with a fast time constant, Some special problems due to the magnetic coupling between the different magnets were investigated by calculation and experiment. Making use of these investigations some different current regulation systems for the nc magnets were implemented and tested experimentally, Finally a step-tuning operation between the modes from TE20, 6 to TE24, 6 in time steps of 1 s has been achieved.
