Non-Thermal Process in a Linear Pinch Device.
Abstract
A low pressure, linear discharge initiated by focusing a pulsed laser beam between two electrodes produces a concentrated thermal plasma of (T sub e) about 8 keV and (N sub e) about 10 to the power of 21/cc. This plasma emits x-ray line radiation arising from highly stripped atoms such as hydrogen and helium-like iron ions. The temperature of the Fe XXV-ion estimated from Doppler line broadening is higher than the electron temperature, in agreement with the results obtained by Peacock, et al. The heating mechanism for attaining such high temperatures during the very short periods of interest is considered, and some experimental results supporting the contributions to the plasma heating by a non-thermal process are presented.
