Experimental Study of Dust Acoustic Waves in the Strongly Correlated Regime

Plasma Physics 2016-04-20 v1

Abstract

Low frequency dust acoustic waves (DAW) were excited in a laboratory argon dusty plasma by modulating the discharge voltage with a low frequency AC signal. Metallic graphite particles were used as dust grains and a digital FFT technique was used to obtain dispersion characteristics. The experimental dispersion relation shows the reduction of phase velocity and a regime where ω/k<0\partial \omega/\partial k < 0. A comparison is made with existing theoretical model.
