论文摘要
结果表明，径向等离子体压力曲线的陡峭导致β的临界值降低，而镜像陷阱中的小规模气球型扰动变得不稳定。这意味着小规模的气球不稳定性会导致径向等离子体轮廓的平滑。这一事实似乎在可用出版物中很少受到关注。还计算了气体动力陷阱的实际磁场的临界β值。在最佳配置中，对于具有抛物线径向压力曲线的等离子体，获得了临界β0.72。
It is shown that steepening of the radial plasma pressure profile leads to a decrease in the critical value of beta, above which small-scale balloon-type perturbations in a mirror trap become unstable. This means that small-scale ballooning instability leads to a smoothing of the radial plasma profile. This fact seems to have received little attention in the available publications. The critical beta values for the real magnetic field of the gas-dynamic trap was also calculated. In the best configuration the critical beta 0.72 is obtained for a plasma with a parabolic radial pressure profile.
