Plasma Heating by a Relativistic Electron Beam. I. Wave Kinetic Equation and Spectral Function

抄録

A new possibility for plasma heating is proposed and theoretical investigation is performed. Under a suitable experimental condition, the wave induced by the two-stream instability and Buneman/ion-acoustic wave induced by the return current can coexist and interact to yield a new contribution to plasma heating by the relativistic electron beam. The authors assume this is the case and develop the formulation necessary for the analysis of the spectral function of turbulent plasma. Detail of the interaction mechanism and numerical estimation of stopping power are given in the following paper (J. Phys. Soc. Jpn. 49 (1980) 1532).
