Laboratory Studies of Effects Associated with Plasma Non-Uniformities (Non-Uniform Magnetic Fields and Non-Uniform Plasma Flows)

9876847D' angelo地球物理和天体物理等离子体具有点与点不同的特性。本研究的目的是进行基本的实验室实验，研究等离子体不均匀性的一些影响。实验是在Q-machine中进行的，重点是当等离子体密度脉冲被发射到会聚的磁场线上时，静电冲击波是如何发展的，以及如果存在非均匀磁场对准的大块等离子体流，磁场电流是如何产生离子声波动的。

9876847D'AngeloGeophysical and astrophysical plasmas have characteristics which vary from point to point. The objective of this research is to perform basic laboratory experiments which investigate some of the effects of plasma non-uniformities. The experiments are conducted in a Q-machine and focus on how electrostatic shock waves develop when plasma density pulses are launched into converging magnetic field lines and how ion-acoustic fluctuations are produced by magnetic field currents if a non-uniform magnetic field-aligned bulk plasma flow is also present.
