聚变装置中的随机边界在托卡马克、仿星器和反场箍缩实验中已经研究了很多年。然而，由于在DIII‐D托卡马克[1，2]中，H模等离子体中的边缘局域模（ELM）已被成功消除，并且具有小的边缘共振磁扰动，因此它们已成为托卡马克中广泛研究的主题。在DIII-D中，随机边界由等离子体外部的线圈产生。那里的磁场由具有非常不同的连接长度的场线组成，这产生了随机体积的三维非均匀结构。扰动等离子体边缘最明显的表现是在热量和粒子通量中观察到的走向线分裂，它随碰撞度而变化。的磁扰动和磁平衡的相互作用是一个共振的性质和结构的随机体积是一个强的函数q95。这被观察为例如通过ECE或汤姆逊散射测量的电子温度的调制。在这项工作中，我们总结了DIII-D中随机边界特性的最新实验结果（© 2010 WILEY-VCH Verlag GmbH & Co.

Stochastic boundaries in fusion devices have been investigated in tokamaks, stellarators and reversed field pinch experiments for many years. However, since edge localized modes (ELMs) have been successfully eliminated in H‐mode plasmas at the DIII‐D tokamak [1,2] with small, edge resonant magnetic perturbations, they have become a widely investigated topic in tokamaks. In DIII‐D stochastic boundaries are produced by coils external to the plasma. The magnetic field there consists of field lines with very different connection lengths, which produces a three dimensional, heterogenous structure of stochastic volume. The most obvious manifestation of the perturbed plasma edge is the strike line splitting observable in heat and particle fluxes, which changes with collisionality. The interaction of the magnetic perturbation and the magnetic equilibrium is of a resonant nature and the structure of the stochastic volume is a strong function of q95. This is observed as a modulation of e.g. electron temperature as measured by ECE or Thomson scattering. In this work we summarize recent experimental findings on properties of the stochastic boundary in DIII‐D (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
