This Letter reports the result of a numerical study of particle transport in self-organized single helicity (SH) and quasi-SH reversed field pinch plasmas. Our code, benchmarked against experimental data, predicts a large improvement in particle transport for SH compared to the standard multiple helicity states. The contribution of neoclassical effects is noted. An estimate of the ambipolar electric field in helical states and in fully stochastic magnetic fields is given.
本信函报告了对自组织单螺旋度（SH）和准SH反向场箍缩等离子体中粒子输运进行数值研究的结果。我们的代码以实验数据为基准，预测与标准多螺旋度状态相比，SH状态下的粒子输运会有大幅改善。文中指出了新经典效应的贡献。给出了螺旋状态和完全随机磁场中双极电场的估计值。
