INTERACTION OF ELECTRON VORTICES UNDER THE INFLUENCE OF BACKGROUND VORTICITY DISTRIBUTION

摘要

We report experimental studies on vortex dynamics carried out recently in Kyoto University by using electron plasmas that are trapped in the Malmberg configuration with variety of initial configurations. This report includes (1) relaxation of many-clump dynamic states to "crystallization", (2) single clump dynamics in a background vorticity distribution, (3) two-clump interaction in a low-level background vorticity distribution, and (4) accelerated "crystallization" of three clumps in a background vorticity distribution. Details are provided in companion papers reported in this workshop.
