The paper summarizes important results of the recent experimental studies performed on the plasma-focus PF-1000 facility operated in Warsaw, Poland, mainly with the pure deuterium filling. Attention is focused on the evolution of toroidal and plasmoidal self-organized structures formed by internal closed currents inside the dense plasma column. The production of hard x-rays and neutrons corresponds with the formation and decay of plasmoids, in which charged particles can be accelerated effectively to high energies, during a release of the magnetic energy from current filaments of high energy density. It is noticed that the studies of laboratory fusion and cosmic plasmas deal with similar problems, e.g., the fast release of the magnetic energy in a form of high-energy charged particle beams.

密集等离子体聚焦中硬 X 射线和中子发射过程中收缩柱的演化

该论文总结了最近在波兰华沙运行的等离子体聚焦 PF-1000 设施进行的实验研究的重要结果,主要填充纯氘。注意力集中在由致密等离子体柱内的内部闭合电流形成的环形和等离子体自组织结构的演化上。硬 X 射线和中子的产生与等离子体团的形成和衰变相对应,其中在从高能量密度的电流灯丝释放磁能期间,带电粒子可以有效地加速到高能量。值得注意的是,实验室聚变和宇宙等离子体的研究处理类似的问题,例如,以高能带电粒子束的形式快速释放磁能。
