提出了一种测定高温等离子体中超热电子的新方法。热电子的存在不仅导致离子丰度的平衡移动,而且导致定性失真。在实验中,通过类H离子和类Li至类F离子的一系列卫星离子的发射,可以观察到这种畸变。广泛的应用范围被证明,甚至适用于光学厚等离子体。对聚变等离子体的典型参数进行了瞬态数值计算。
A new method for the determination of hot electrons in high-temperature plasmas is proposed. The presence of hot electrons leads not only to a balance shift of the ion abundance but also to a qualitative distortion. In experiments the distortion is observable through the emission of H-like and the series satellites of Li- to F-like ions. The wide range of application is demonstrated and holds even for optically thick plasmas. Transient numerical calculations are carried out for typical parameters of fusion plasmas.
