在大螺旋装置（LHD）的低密度放电中，由于LHD具有强大的切向中性束注入系统，因此预计会出现各向异性压力。我们研究了观测到的鞍环磁通与反磁通之比的行为，并将结果与蒙特卡罗技术和稳态Fokker-Planck解预测的光束压力各向异性进行了比较。我们展示了在LHD中通过磁测量估计压力各向异性程度的可能性。
In low density discharges of a Large Helical Device (LHD), anisotropic pressure is expected because the LHD has powerful tangential neutral beam injection systems. We study the behaviour of the ratio of the observed saddle loop flux to the diamagnetic flux, and the results are compared with the predicted beam pressure anisotropy by a Monte Carlo technique and the steady state Fokker–Planck solution. We show the possibility of the degree of pressure anisotropy being estimated by magnetic measurements in the LHD.
