Abstract

A Penning discharge was investigated photoelectrically as a light source from 100 A to 300 A. The source showed reasonable stability-10% over an hour's operation. Bright spectral lines observed were a mixture of lines from the filling gas (Ne) and from sputtered cathode material (Al). The discharge was found to be an intense line source; an estimate of the brightness of the 160 A Al IV lines shows them to be comparable with the highly ionized metal lines appearing in a pulsed tokamak discharge. Satellites of the Al IV resonance lines at 160 A appear clearly in the spectra.

摘要

对潘宁放电进行了光电研究，将其作为一种波长范围从100埃至300埃的光源。该光源在一小时的运行过程中显示出合理的稳定性——波动为10%。观察到的明亮光谱线是填充气体（氖）的谱线与溅射阴极材料（铝）的谱线的混合。该放电被发现是一个强线光源；对160埃处铝IV谱线亮度的估计表明，它们与脉冲托卡马克放电中出现的高离化金属谱线相当。160埃处铝IV共振线的伴线在光谱中清晰可见。
