Abstract

Soft x-ray emission from a Mather-type plasma-focus device (PF-1000) operated at ∼400 kJ was measured. The high density and temperature plasma were generated by the discharge in the deuterium-argon gas mixture in the modified (high-current) plasma-focus configuration. A spherically bent mica crystal spectrograph viewing the axial output of the pinch region was used to measure the x-ray spectra. Spatially resolved spectra including the characteristic x-ray lines of highly ionized Ar and continua were recorded by means of an x-ray film. The x-ray emission of PF-1000 device was studied at different areas of the pinch.

摘要

对运行于约400千焦能量的马瑟型等离子体聚焦装置（PF - 1000）的软X射线发射进行了测量。高密度和高温等离子体是在改良（高电流）等离子体聚焦结构的氘 - 氩混合气体放电过程中产生的。使用一台观察箍缩区轴向输出的球形弯曲云母晶体光谱仪来测量X射线光谱。通过X射线胶片记录了包括高电离态氩的特征X射线谱线和连续谱在内的空间分辨光谱。在箍缩区的不同区域对PF - 1000装置的X射线发射进行了研究。
