The effects of finite space charge on the equilibrium characteristics of charges confined in a Paul trap are investigated. It is found that space charge introduces two effects that have opposing influences on the confining pseudopotential well. The effect of electrostatic repulsion between like charges is to make the potential well shallower, but the plasma collective response can lead to a deepening of the well. Illustrative numerical solutions of thermal equilibria as well as an approximate analytical equilibrium are discussed.
