Abstract.  A high-$\beta$ equilibrium was theoretically predicted by the Beltrami/Bernoulli conditions. In order to obtain such attractive plasmas an innovative method using electrically non-neutralized plasmas has been proposed, and the experiments to demonstrate it have been conducted on Proto-RT and BX-U. Energetic electrons are successfully injected across vacuum magnetic fields and a strong self-electric field, which is sufficient to drive a super-Alfvenic flow in a target plasma, is formed by the electrons. However, in the target plasma frictional forces would damp the flow, resulting in loss of the electrons. An initial experimental result on the loss of electrons is presented.
