即使在没有直流电场的情况下，沿一个方向行进的电子的优先加热也可以支持电流。一个直接的含义是，即使是携带很少的环向动量的波，如电子回旋波，作为在托卡马克中产生稳态环向电流的一种手段也可能是有吸引力的。导出了单位功耗产生的电流的解析表达式，与数值计算结果吻合得非常好。
Preferential heating of electrons traveling in one direction can support a current even in the absence of a dc electric field. An immediate implication is that even waves which carry little toriodal momentum, such as electron cyclotron waves, may be attractive as a means for generating steady-state toroidal current in a tokamak. An analytical expression is derived for the current generated per power dissipated, which agrees remarkably well with numerical calculations.
