Parametric upward conversion of the electromagnetic wave frequency in a relativistic electron flux drifting in a magnetized plasma
Abstract
The paper is concerned with the combined effect of a plasma and of a magnetic field on the parametric interaction of two transverse electromagnetic waves with the space charge wave of a relativistic electron flux. It is shown that absolute instability is possible in such a system in addition to convective instability; the instability can be stabilized by selecting approximate parameters. The plasma existing in the drift region of the relativistic electron beam increases the amplification coefficient.
