Non-Canonical Gyrotrons

Аннотация

We consider some gyrodevices, which differ from the gyrotron canon, in particular, devices with sectioned active media and/or interaction spaces, and non-tubular helical electron beams, and non-cylindrical (coaxial, quasioptical, echelette, etc.) cavities. Promising variants of noncanonical gyrotrons, including multi-beam and multi-barrel tubes, are considered from the viewpoint of frequency tuning and mode selection enhancement.
