OBSERVATION OF SURFACE MODES EXCITED BY AN ELECTRON BEAM IN A PLASMA,

Abstract

Unstable oscillations at frequencies below the plasma frequency are observed at the plasma boundary during the interaction of an electron beam with a plasma. These oscillations are interpreted as the eitenmodes of the inhomogeneous plasma boundary, driven into instability by the beam. (Author)
