Frequency up-shift for cyclotron-wave instability on a relativistic electron beam

[[abstract]]The axial drift of a relativistic electron beam along a uniform magnetic field is shown theoretically to lead to significant frequency up-shifts for linear cyclotron-wave instabilities driven by velocity-space anisotropy. This mechanism suggests novel means for the development of devices for generation of intense far-infrared power.[[fileno]]2010126010015[[department]]物理
