Two-dimensional macroscopic shapes of lithium ion and electron plasmas after elapse of two-fluid plasma state

We have conducted an experiment in which pure lithium-ion and electron plasmas are mixed by simultaneously confining the plasmas in a nested-penning trap to experimentally explore a two-fluid plasma state. Preliminary data show that the Li+ ion plasma, after plasma mixing, is divided into small circle- and crescent-shaped parts over time. Conversely, the e− plasma after plasma mixing shifts or expands radially.
