论文摘要
研究了``刚性''长笛和气球模式在轴对称镜陷阱中$ m = 1 $的稳定，借助理想的在存在的情况下，在存在的情况下，在没有末端MHD锚的情况下进行了横向。在模型中，对各向异性等离子体进行了计算，该模型在将快速中性原子的光束注射到磁场中的压力分布与陷阱轴的最小角度最小。假定侧壁具有可变半径的圆柱体的形状，因此在扩大的刻度上，它重复了等离子体柱的形状。 已经发现，为了通过理想地进行侧壁有效稳定列出的模式，参数beta（$β$，等离子体压力与磁场压力的比率）必须超过一些临界值$β_ {\ text {crit {crit}}} $。当与模仿MHD端稳定器的指挥侧壁和指挥端板结合在一起时，有两个关键的β值和两个稳定区域$ 0 <β<β_ {\ text {crit} $ and $β_{\ text _ {\ text {crit} 2} 2} <β<β<1 $ $ 0 $ 0的范围<1 $ bet bet n y。 研究了临界β对等离子体各向异性，镜比的依赖性以及血浆和侧壁之间真空间隙的宽度。与其他作者的作品相反，该作者的作品专门针对具有尖锐边界的等离子体模型，我们计算了许多弥漫性径向压力剖面和几个轴向磁场轮廓的稳定区域的边界。
The stabilization of ``rigid'' flute and ballooning modes $m = 1$ in an axisymmetric mirror trap with the help of an ideally conducting lateral both in the presence and in the absence of end MHD anchors is studied. The calculations were performed for an anisotropic plasma in a model that simulates the pressure distribution during the injection of beams of fast neutral atoms into the magnetic field minimum at a right angle to the trap axis. It was assumed that the lateral wall has the shape of a cylinder with a variable radius, so that on an enlarged scale it repeats the shape of the plasma column. It has been found that for the effective stabilization of the listed modes by an ideally conducting lateral wall, the parameter beta ($β$, the ratio of the plasma pressure to the magnetic field pressure) must exceed some critical value $β_{\text{crit}}$. When combined with a conducting lateral wall and conducting end plates imitating MHD end stabilizers, there are two critical beta values and two stability zones $0<β<β_{\text{ crit}1}$ and $β_{\text {crit}2}<β<1$ that can merge, making the entire range of allowable beta values $0<β<1$ stable. The dependence of the critical betas on the degree of plasma anisotropy, the mirror ratio, and the width of the vacuum gap between the plasma and the lateral wall is studied. In contrast to the works of other authors devoted to the plasma model with a sharp boundary, we calculated the boundaries of the stability zone for a number of diffuse radial pressure profiles and several axial magnetic field profiles.
