贝尔特拉米/伯努利条件理论上预测了高β平衡。为了获得如此有吸引力的等离子体，人们提出了一种使用非电中和等离子体的创新方法，并在 Proto-RT 和 BX-U 上进行了证明该方法的实验。高能电子成功地注入真空磁场，并由电子形成足以驱动目标等离子体中的超阿尔芬尼流的强自电场。然而，在目标等离子体中，摩擦力会抑制流动，导致电子损失。给出了电子损失的初步实验结果。
A high-β 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.
