Low frequency investigation of the ion-ion hybrid resonance In two-ion species plasmas

Abstract

The ion-ion hybrid resonance was investigated in neon-krypton and neon-argon plasmas. A signal was transmitted from one coil to a second coil to which the first was inductively coupled. A strong noise interference was encountered. A lock-in amplifier and filter system was tested for noise rejection, as was a system employing a third coil and a differential amplifier circuit. Variation of power transmitted and varying coil spacing were also tried. Some results were obtained but they were not definite or reproducible since the noise rejection techniques were not adequate. A review of the various theories pertaining to the ion-ion hybrid resonance and reeommndatfons for further work are presented.
