Abstract
[[abstract]]The electrostatic cyclotron instability driven by a relativistic mechanism is analyzed with a small-signal theory and is shown to be a significant noise amplification mechanism in gyrotrons. The mode is localized in the electron beam, with a growth rate strongly dependent of the wavelength and electron density but insensitive to the velocity spread. It is also shown that these localized modes have little, if any, coupling to the circuit and, hence, may not be easily detected or stabilized.[[fileno]]2010126010050[[department]]物理This publication has 10 references indexed in Scilit:
