ABSTRACT:
A gyrotron device e.g. a gyrotron oscillator (FIG. 3) or a gyrotron amplifier (FIG. 4) in which a circular waveguide is dimensioned to operate in a transverse electric mode (TE.sub.01) as an interaction region at an RF frequency .omega..sub.o. An injection means directs a beam of electrons, in the form of a hollow cone, into the waveguide and a solenoid generates a magnetic field, extending axially along the waveguide, which causes the electrons in the beam to gyrate at the cyclotron frequency .omega..sub.c. A solenoid coil, mounted on the side of the injection means remote from the solenoid, is used to modify the magnetic field prevailing in the vicinity of the hollow cone, to cause the field lines to extend along the electron beam.
