This paper describes the structure of a higher extreme ultraviolet (XUV) emission and plasma density region which surrounds a pinched dense-plasma column. It is interpreted as a toroidal-like plasma formation, which is flowing by a closed current with poloidal and toroidal components upon its surface. This current produces a local magnetic field, which separates the external discharge current from the surface of the dense pinch column. We estimated the values of closed currents as well as magnetic- and plasma-pressures in this column and its surrounding on the basis of the measured distribution of interferometric fringes and intense XUV emission, recorded during the pinch stagnation phase. The considered layer forms the region in which the magnetic energy can be conserved, and during its decay, the acceleration of fast deuterons can take place.

等离子聚焦放电致密箍缩柱外闭合电流和磁场的特性

本文描述了围绕压缩致密等离子体柱的更高极紫外 (XUV) 发射和等离子体密度区域的结构。它被解释为环形等离子体形成，它由闭合电流流动，其表面上有极向和环形分量。该电流产生局部磁场，将外部放电电流与密集夹柱表面隔开。我们根据在收缩停滞阶段记录的干涉条纹和强 XUV 发射的测量分布估计了该柱及其周围的闭合电流以及磁和等离子体压力的值。所考虑的层形成了磁能可以守恒的区域，并且在其衰变期间，可以发生快速氘核的加速。
