The primary interest of our research group is to study the intersection between non neutral plasma physics and beam physics. The research activities concern characteristics of space charge lenses, high current beam transport in toroidal kind magnetic field, space charge neutralization and diagnostics of ion beams. Electron clouds in space charge lenses show interesting plasma properties, and can be used for beam focusing. The magnetostatic ring borrows stellarator concept from plasma physics in accelerator physics where different types of storage rings for different purpose have been used or newly proposed. The storage ring with toroidal magnetic field provides opportunities to study topics in beam physics to next the level of understanding. The diagnostics experiments are designed to give insight of the plasma behaviour in small volume source. The plasma parameters like electron temperature, ion temperature, density, and ion species play effective role in extracted beam properties like current, emittance or beam profile.
