Nonlocal Reflection in a Warm Plasma in the Presence of an Electron Beam,
Abstract
The document discusses in part A, the reflection mechanism of the longitudinal wave in an inhomogeneous plasma due to an external static electric field when an electron streaming beam is present and its direction is parallel with the external electric field. The reflection coefficient of the nonlocal effect is also calculated. Baldwin calculated the reflection coefficient due to inhomogeneity without streaming beam. But, most of the plasmas in laboratories have some kinds of streaming beams. Therefore, the result obtained here is a more realistic problem than Baldwin's. Since the presence of the beam manifests itself in the exponent, the effect may be significant. In part B, the nonlocal reflection due to the presence of an electron streaming beam whose direction is perpendicular to the direction of the longitudinal wave is studied. It is obvious that the effect of an additional beam is very small, in other words, there is no synchronous region (or the resonant point) between the space charge wave and the plasma wave. (Author)
