提出了一种测量磁化等离子体中离子能量分布的探针法。具有端塞的圆柱形探针平行于磁场定向，并用于减少电子对总探针电流的贡献。离子的总电流的二阶导数的贡献被确定通过实验与不同的探头方向和磁场的强度。从测量的离子能量分布得到的离子密度与从测量的电子能量分布得到的电子密度是一致的。
A probe method for measurement of the ion energy distribution in magnetized plasmas is proposed. A cylindrical probe with end plugs is oriented parallel to the magnetic field and used to reduce the electron contribution to the total probe current. The contribution of ions to the second derivative of the total current is identified by experiments with different probe orientation and strength of the magnetic field. The ion density obtained from the measured ion energy distribution is in good agreement with the electron density obtained from measured electron energy distribution.
