Abstract

A self-excited vertical oscillation of dust grains in the sheath region of an rf-discharge plasma has been observed. The variation of amplitude with pressure and input power was measured. Dramatic increase of oscillation amplitude was found for pressures below 4.5 Pa. Possible excitation mechanisms are considered.
