Amplification of Extraordinary Waves through Relativistic Magnetized Plasma

Abstract

We observe amplification of extraordinary waves which is interpreted as negative absorption of the relativistic magnetized plasma confined in a mirror machine. Experimental results are explained well by the relativistic kinetic theory with the assumption of an isotropic peaked distribution, $f\left(p\right)\mathrm{}\propto p^l\exp (-\frac{\epsilon }{T})$.
