Rao, K V.N.

The phenomenon of radio frequency electromagnetic wave interaction in gaseous plasmas is discussed. The technique of microwave interaction with a plasma and the simultaneous observation of the afterglow light intensity were employed to investigate gaseous plasmas immersed in external magnetic fields. Attention was focused especially on the effects produced in such plasrias when one of the simultaneously propagating microwaves is in electron-cyclotron resonance. It is demonstrated that for relatively modest amplitudes of the resonating wave the kinetic energy of the electrons increases considerably, which in turn effects the electron collision frequency and the magnetic field control of the plasma confinement. The enhandcement of the electronic energy caused by the cyclotron resonance absorption of microwave energy is evidenced in the propagation characteristics of resonant and non-resonant electromagnetic waves, the visible excitation light intensity of the plasma, and the emission of microwave noise power from the plasma.
