Large-amplitude disturbances caused by ion-rich sheath motion
Abstract
We present the first detailed experimental study of the plasma response to movement of a plane ion-rich sheath. The results show clearly that ion rarefaction waves are associated with sheath expansion while ion enhancement (‘compressive’) waves are formed on sheath collapse. The data are compared successfully with a nonlinear theory which includes the presence of a presheath prior to the sheath motion.
