Experiments will be conducted on dense laser produced plasmas embedded in a backgroundplasma of considerably lower density (by factor of ~ 1/1000). There are two objectives. The firstis the study of the interaction of intense microwaves (microwave absorption and heating) with thedense plasma that can have density gradients parallel or perpendicular to the magnetic field. The second is a study of the deposition of energy and momentum of colliding dense plasma blobs in the background plasma. Both of the experiments address fundamental problems in plasma physics and also have applications to space science such as ionospheric heating and coronal mass ejections.

实验将在嵌入密度相当低的背景等离子体中的致密激光产生的等离子体上进行（约1/1000）。有两个目标。 第一是研究强微波（微波吸收和加热）与密度梯度平行或垂直于磁场的稠密等离子体的相互作用。第二个是研究碰撞稠密等离子体团在背景等离子体中的能量和动量沉积。 这两个实验都解决了等离子体物理学中的基本问题，也应用于电离层加热和日冕物质抛射等空间科学。
