Abstract

One-component (non-neutral) microplasmas are created in a linear electyrodynamic trap when confining charged microparticles under standard pressure and temperature (STP) conditions. In this paper principle of a method aimed to characterize and to manipulate the stored microparticles is proposed. The method is based on the excitation of the parametrical resonance of the stored microparticles. The excitation field consists of an acoustic wave generated by an external loudspeaker. The effect of the excitation field is observed by analyzing the variation of the intensity of the light scattered by the stored microparticles located on the linear trap axis. Preliminary results are reported..
