Uniform magnetic-field-induced free-electron laser in a waveguide
Abstract
We discuss how a uniform focusing magnetic field can affect the performance of a microwave source such as a backward-wave oscillator. It is argued that the uniform magnetic field can cause the existence of a free-electron laser within the waveguide; the Doppler up and/or down-shifted cyclotron radiation can undergo amplification (or absorption) due to interaction of electrons (in helical orbits) with electromagnetic radiation.
