论文摘要
提出了一种动态缓解措施，以用于Z-电流驱动的磁化等离子体柱的香肠和扭结不稳定性生长。我们提出了一种基于相控制的动态缓解方法，以平滑等离子体的非均匀性并减轻扰动的血浆系统的不稳定性生长。在本文中，我们发现Z-电流电子轴的摇摆运动会引起相处的扰动，从而成功缓解了香肠和扭结不稳定性的生长。通常，血浆不稳定性从扰动中出现，并且扰动阶段通常是未知的。但是，如果扰动阶段是由设计的驱动器摇摆行为知道或主动施加的，则不稳定生长将受到施加的扰动的叠加来控制和减轻。本文的结果表明，摇摆的Z-电流电子束将改善血浆柱稳定性和均匀性。
A dynamic mitigation is presented for sausage and kink instability growths of a z-current driven magnetized plasma column. We have proposed a dynamic mitigation method based on a phase control to smooth plasma non-uniformities and to mitigate the instability growth in perturbed plasma systems. In this paper we found that a wobbling motion of the z-current electron axis induces a phase-controlled perturbation, so that the growths of the sausage and kink instabilities are successfully mitigated. In general, plasma instabilities emerge from perturbations, and the perturbation phase is normally unknown. However, if the perturbation phase is known or actively imposed by, for example, a designed driver wobbling behavior, the instability growth would be controlled and mitigated by a superimposition of the perturbations imposed. The results in this paper demonstrate that the wobbling z-current electron beam would provide an improvement in the plasma column stability and uniformity.
