Cyclotron maser instability
WebJul 25, 2024 · A kinetic (or maser) instability applies when the imaginary part of the response function is included and leads to negative absorption. Maser growth requires that the growth rate be less than the bandwidth of the growing waves. Phase mixing then occurs faster than wave growth, implying that the random phase approximation (RPA) applies. WebOct 31, 2013 · In short, the problem of cyclotron maser is still an active research area with many outstanding issues. [7] The purpose of the present paper is to revisit the classic …

WebDec 8, 2024 · Emission is produced when the plasma enters a state of energetic excitation which results in deformation of the electron distribution function. Under certain conditions this leads to “quasi-coherent” … WebIt has been postulated that a cyclotron maser instability driven by the horseshoe distribution is the source of this Auroral Kilometric Radiation (AKR). An experiment was created, scaled to laboratory dimensions, to simulate this naturally occurring phenomenon. Frequencies were altered from 100's kHz to GHz by increasing the magnetic field ...
