Abstract From many parameters affecting ion emission angular distributions in a plasma focus device (PFD), gas pressure is a parameter highly affecting ion emissions, the mechanisms of which have yet to be further understood. In this research, effects of hydrogen gas pressure up to 100 mbar were studied on angular distributions of run-away hydrogen ions generated directly from the “anode cathodes assembly”. In order to demonstrate further the emission of such ions and study the effect of gas pressure on the ion emissions, a novel self-invented panorama mega-size polycarbonate cylindrical ion image detector was used for wide-angle panorama image detection of run-away hydrogen ions from the “anode cathodes assembly”. The mega-size detectors were processed in our novel single-cell panorama electrochemical etching ion image processing system constructed for this study. The studies confirmed effective detection of images of high intensity run-away hydrogen ions; observation of 6 “hydrogen ion cathode shadowgrams” by the unaided eyes; estimation of total hydrogen ion tracks under different gas pressures and in particular a high proof of strong source of ion emission from the “anode cathodes assembly” partially responsible for formation of cathode shadowgrams formed on the detectors.

新型全景“阳极阴极组件”失控氢离子图像研究在不同气压下的 4π 等离子体聚焦装置空间中

摘要 从影响等离子体聚焦装置（PFD）中离子发射角分布的许多参数来看，气压是一个对离子发射影响很大的参数，其机理还有待进一步了解。在这项研究中，研究了高达 100 毫巴的氢气压力对直接从“阳极阴极组件”产生的失控氢离子角分布的影响。为了进一步论证此类离子的发射并研究气体压力对离子发射的影响，采用一种新型的自主发明的全景超大尺寸聚碳酸酯圆柱离子图像检测器对失控氢进行广角全景图像检测。来自“阳极阴极组件”的离子。超大尺寸探测器在我们为本研究构建的新型单细胞全景电化学蚀刻离子图像处理系统中进行处理。研究证实了对高强度失控氢离子图像的有效检测；用肉眼观察6个“氢离子阴极阴影图”；估计不同气压下的总氢离子轨迹，特别是“阳极阴极组件”的强离子发射源的高度证明，部分原因是在探测器上形成阴极阴影图。
