普林斯顿贝塔实验（PBX）托卡马克已经研究了有利于高..β.放电的豆形结构。已成功形成强烈凹进的豆形等离子体，并且在注入中性束功率为 5 MW 时获得了超过 5% 的 β 值。这些高 β 放电仍然处于气球模式的第一稳定状态，并且 MHD 稳定性分析表明外部扭结是造成当前 ..β.. 限制的原因。
Bean-shaped configurations favorable for high ..beta.. discharges have been investigated in the Princeton Beta Experiment (PBX) tokamak. Strongly indented bean-shaped plasmas have been successfully formed, and beta values of over 5% have been obtained with 5 MW of injected neutral beam power. These high beta discharges still lie in the first stability regime for ballooning modes, and MHD stability analysis implicates the external kink as responsible for the present ..beta.. limit.
