摘要：

Dust acoustic waves (DAW) in a particle cloud trapped in an anodic argon plasma are investigated. At certain parameters self-excited waves are observed. In stable or weakly unstable regimes DAWs can be excited externally. The experimental data is critically compared with fluid and kinetic models. It is found that a kinetic model is capable of describing the observed DAW dispersion while the standard fluid model fails. The high growth rate ensures that the instability reaches high wave amplitudes despite the small dimensions of the dust region.
