摘要

利用 SOLPS-ITER 边缘等离子体模拟分析了球形托卡马克 Globus-M2 的刮离层中高场边高密度（HFSHD）制度的形成和高场边（HFS）极状电场的作用。讨论了 HFS 极性电场符号以及径向漂移通量对放电密度的影响。结果表明，与 ASDEX 升级版一样，HFS 极性电场是在 Globus-M2 托卡马克中形成 HFSHD 状态的关键因素。研究表明，在小型球形托卡马克中形成 HFSHD 的物理学原理与 Kaveeva 等人（2009 年第 36 届 EPS 等离子体物理学会议）提出的原理相似，并且与后来在 ASDEX Upgrade 上进行的实验观测和建模相符。

Modeling of high-field-side high-density regime in the Globus-M2 tokamak

Formation of a high-field-side high-density (HFSHD) regime and the role of the high-field-side (HFS) poloidal electric field in the scrape-off layer of the spherical tokamak Globus-M2 are analyzed using SOLPS-ITER edge plasma simulations. The dependence of the HFS poloidal electric field sign and, consequently, radial drift fluxes on the discharge density is discussed. It is demonstrated that the HFS poloidal electric field is the key element in the formation of a HFSHD regime in the Globus-M2 tokamak as in ASDEX Upgrade. It is demonstrated that the physics of HFSHD formation in a small spherical tokamak is similar to that suggested by Kaveeva et al (2009 36th EPS Conf. on Plasma Physics) and is in line with experimental observations and modeling, performed later on ASDEX Upgrade.

期刊介绍： Plasma Physics and Controlled Fusion covers all aspects of the physics of hot, highly ionised plasmas. This includes results of current experimental and theoretical research on all aspects of the physics of high-temperature plasmas and of controlled nuclear fusion, including the basic phenomena in highly-ionised gases in the laboratory, in the ionosphere and in space, in magnetic-confinement and inertial-confinement fusion as well as related diagnostic methods. Papers with a technological emphasis, for example in such topics as plasma control, fusion technology and diagnostics, are welcomed when the plasma physics is an integral part of the paper or when the technology is unique to plasma applications or new to the field of plasma physics. Papers on dusty plasma physics are welcome when there is a clear relevance to fusion.
