title = "Microwave generation from an electron horseshoe distribution: theory and experiment",
abstract = "When a beam of electrons encounters an increasing magnetic field along its vector of motion, conservation of the magnetic moment results in the formation of a crescent or horseshoe-shaped velocity distribution. A scenario analogous to this occurs in the terrestrial auroral zone where particles are accelerated into the polar regions of the earth's magnetic dipole and expand adiabatically in velocity space. The resultant horseshoe-shaped velocity distribution has been shown to be unstable to a cyclotron-maser type instability [1-3]. This instability has been postulated as the mechanism responsible for auroral kilometric radiation and also nonthermal radiation from other astrophysical bodies [4]. In this paper we describe both theory, simulations and a laboratory experiment to investigate the generation of microwave radiation when an electron beam is magnetically compressed by a factor of 35.",
