Methods for controlling accurately the diameter d e of a pure electron plasma in a nested trap of the BX-U machine are described. By controlling the acceleration voltages and the number of electron guns activated, we can successfully change d e over the range between 0.28 and 2.27 cm. Therefore, d e can be made almost exactly the same as the diameter of a lithium ion plasma enabling the investigation of a two-fluid plasma state by using non-neutral plasmas.
