Abstract

We perform experiments where lithium ion and electron plasmas are simultaneously confined in a nested trap to detect two-fluid plasma states. However, the behavior of charged particles in the nested trap is unexplained. Results of experiments demonstrate that the number of charged particles in the outer wells of the nested trap rapidly decreases and that peculiar deformations in ion and electron plasmas cause in some conditions.
