Experimental observation of the resonances of a bounded plasma in the electron and magneto-ion domain

A hot electron and ion theory of RF power absorption utilising the resonances of a finite plasma cylinder, having the distinct feature of encompassing both the magneto-ion and the electron domain ( omega <or= omega ci up to omega ce and omega pe ) is verified experimentally in the following parameter range: magnetic field strengths of 0-1000 G, electron densities (N e ) of the order of 10 9 -10 11 cm -3 , electron temperatures T e of a few eV, ion temperatures T i approximately=0, 10 5 Hz<f= omega /2 pi <10 9 Hz, axial wavelengths lambda /sub ///=2 pi /k/sub /// of a few centimeters.
