分别计算了由电子伯恩斯坦波(EBW)和电子自举效应驱动的电流，并用动力学程序确定了它们之间的协同程度。检查了目标β=40%Nstx[M.Ono，S.Kaye，M.Peng等人，由M.Spak(国际原子能机构，维也纳，奥地利，1999年)编辑的第17届国际原子能机构聚变能会议论文集，第3卷，第1135页]等离子体。碰撞准线性CQL3D Fokker-Planck程序中的一个简单的自举模型(国家技术信息服务文献编号：DE93002962)在这些研究中使用：在捕获通过边界处的速度空间中，过渡电子分布与捕获电子分布相关联，对于共通过/反通过区域，俘获电子分布径向向外/向内移动半香蕉宽。该模型与标准的自举电流计算在等离子体半径的60%范围内符合得很好。电子束焊接功率在4 mW以下时，协同净自举电流相对较小。本地，启动..。
Current driven by electron Bernstein waves (EBW) and by the electron bootstrap effect are calculated separately and concurrently with a kinetic code to determine the degree of synergy between them. A target β=40% NSTX [M. Ono, S. Kaye, M. Peng et al., Proceedings of the 17th IAEA Fusion Energy Conference, edited by M. Spak (IAEA, Vienna, Austria, 1999), Vol. 3, p. 1135] plasma is examined. A simple bootstrap model in the collisional-quasilinear CQL3D Fokker–Planck code (National Technical Information Service document No. DE93002962) is used in these studies: the transiting electron distributions are connected in velocity space at the trapped-passing boundary to trapped-electron distributions that are displaced radially by a half-banana-width outwards/inwards for the co-passing/counter-passing regions. This model agrees well with standard bootstrap current calculations over the outer 60% of the plasma radius. Relatively small synergy net bootstrap current is obtained for EBW power up to 4 MW.
