Plasma Wave Turbulence and Electromagnetic Radiation Caused by Electron Beams.
Abstract
Research was completed on a program to understand the mechanisms by which mildly relativistic electron beams can generate microwave radiation when injected into plasmas. The chief phenomena found to be involved were (1) stimulation compton conversion of Langmuir waves excited by relativistic e beams and (2) multiple Raman up conversion of radiation from pre-existing Langmuir turbulence. Numerical programs were developed for computing the evolution of beam excited Langmuir waves into strongly turbulent states. It was further, experimentally determined that quiet plasmas with low level of ambient density fluctuations were necessary in order to obtain optimum radiation.
