This award supports a research program on the nonlinear interaction of dense plasmas with magnetic fields. The research will be done in a large laboratory plasma in a rarely explored parameter regime where only the electrons interact with the magnetic field, but not the ions, while both species are coupled via space-charge electric fields. The interplay between two different fluids with time-varying electromagnetic fields leads to a variety of unexplored nonlinear effects. This parameter regime is called electron magnetohydrodynamics. Its nonlinear effects may lead to magnetic turbulence which is of intrinsic interest and considered important in magnetic reconnection.

该奖项支持一项关于密集等离子体与磁场的非线性相互作用的研究计划。 这项研究将在一个大型实验室等离子体中进行，在一个很少探索的参数范围内，只有电子与磁场相互作用，而不是离子，而这两种物质通过空间电荷电场耦合。两种不同的流体与时变电磁场之间的相互作用导致了各种未探索的非线性效应。这个参数区域称为电子磁流体力学。 它的非线性效应可能导致磁湍流，这是本征的兴趣，并认为在磁场重联的重要。
