This grant is for investigations of highly nonlinear magnetic and electric field configurations which are of interest to space plasma physics. The unique feature of the laboratory experiment is the capability to fully map three-dimensional, time dependent vector fields such as electric and magnetic fields and to drive current systems and space charge distributions. Configurations of interest are the propagation of intense current pulses and charged particle beams through magnetized plasmas. Such phenomena arise naturally in solar flares, auroral arcs, and current sheets. *** //

这项拨款用于研究空间等离子体物理学感兴趣的高度非线性磁场和电场结构。实验室实验的独特之处在于能够完全绘制三维，时间相关的矢量场，如电场和磁场，并驱动电流系统和空间电荷分布。感兴趣的结构是强电流脉冲和带电粒子束通过磁化等离子体的传播。这种现象自然地出现在太阳耀斑、极光弧和电流片中。*** //
