A new method of magnetic energy pumping into a plasma

In the case of high-intensity plasmons, interaction processes among the plasmons are more probable than interaction processes of plasmons with plasma particles; plasma relaxation occurs in two stages: first, statistical equilibrium in the plasmon sub-system is established, characterized by a temperature different from that of particles, and then in a slower process equality of plasmon and particle temperatures is established.The plasmon energy may be increased by slowly modulating the external magnetic field on which the plasmon frequencies depend. The energy pumped into the plasmon sub-system by this method — which may be called the method of magnetic pumping — may be much higher than the Joule heat immediately obtained by the particles. The energy obtained by plasmons will be transferred slowly to the particles; in the plasmon sub-system itself a stationary energy level will be established. Thus, in a non-isothermal plasma mainly the electrons will be heated.
