Electron-Cyclotron-Maser Observable Modes
We investigated wave amplification through the Electron-Cyclotron-Masermechanism. We calculated absorption and emission coefficients without any approximations, also taking into account absorption by the ambient thermal plasma. A power-law energy distribution for the fast electrons was used, as is indicated by X-ray and microwave observations. We developed a model for the saturation length and ...
متن کاملThe electron cyclotron maser
The electron cyclotron maser (ECM) is based on a stimulated cyclotron emission process involving energetic electrons in gyrational motion. It constitutes a cornerstone of relativistic electronics, a discipline that has emerged from our understanding and utilization of relativistic effects for the generation of coherent radiation from free electrons. Over a span of four decades, the ECM has unde...
متن کاملLinear Theory of an Electron Cyclotron Maser
The linear theory of an electron cyclotron maser (ECM) operating at the fundamental is developed. A set of analytic expressions, valid for all TE cavity modes, is derived for the starting current and frequency detuning using the Vlasov-Maxwell equations in the weakly relativistic limit. These results are applicable for an arbitrary electron velocity distribution as well as any longitudinal dist...
متن کاملA new approximation of electron-cyclotron-maser frequencies
We present a new approximation for the frequencies where electron-cyclotron-maser is produced by a loss-cone distribution. This approximation is fully relativistic, and is good also for masering frequencies far from the cyclotron harmonics.
متن کاملSaturation of electron cyclotron maser by lower-hybrid waves
We perform a numerical study on the quasilinear relaxation of an electron cyclotron maser on the initially dominant mode. We focus thereby on a situation where the initially dominant modes are quasi-electrostatic lower hybrid (lh) waves, which have not been treated in preceding studies. To this end, we chose 0.2 ≤ ωp/ωBe < 0.5 (ωp: plasma-, ωBe: electron cyclotron frequency) and an initial loss...
