Amplification of Nonpotential Waves in a Magnetized Beam–Plasma System Taking into Account the Evolution of the Plasma

Аннотация

We have analyzed the beam instability taking into account nonpotential effects in a completely magnetized plasma with a density varying slowly with time. It is shown that a frequency shift appears in the amplified signal (during the propagation in such an electrodynamic system); analytic relations determining this shift have been obtained.
