PLASMA RESEARCH.
Abstract
Progress is reported on experimental and theoretical research in problems of creation, containment, heating, stability, radiation, and measurement of the physical and electromagnetic properties of high and low temperature plasmas. The hot-electron experiment operated without difficulty during most of the report period. Most of the effort was concerned with obtaining adequate data to determine the absolute intensity of the synchrotron radiation emitted by the hot-electron plasma. The electron and loss energy analyzer was completed, and the electron end-loss plasma camera used in conjunction with an image converter was used to improve the estimates of the size and location of the plasma. The inconclusive results of the laser-scattering experiments have led to a study of the scattering of laser photons by a hot-electron plasma. A turbulent heating experiment was performed in order to study ion heating by an electron current modulated at the ion-cyclotron frequency. Calibration of the ion energy analyzer is proceeding. A description of the turbulent heating experiment is presented. The experimental apparatus for plama instability experiments is being prepared. An analysis of flute modes in a mirror machine plasma with diffused boundary was completed. Related research includes the testing of a computer model for nonlinear investigation of plasma interchange instability, investigation of the damping and instabilities of cyclotron waves in a plasma, and the study of nonlinear interaction of an electron with an electromagnetic wave.
