Title: 自共振去除镜像机器中的聚变产物

Abstract: Magnetic confinement fusion reactors produce ash particles that must be removed for efficient operation. It is suggested to use autoresonance (a continuous phase-locking between anharmonic motion and a chirped drive) to remove the ash particles from a magnetic mirror, the simplest magnetic confinement configuration. An analogy to the driven pendulum is established via the guiding center approximation. The full 3D dynamics is simulated for $\alpha$ particles (the byproduct of DT fusion) in agreement with the approximated 1D model. Monte Carlo simulations sampling the phase space of initial conditions are used to quantify the efficiency of the method. The DT fuel particles are out of the bandwidth of the chirped drive and, therefore, stay in the mirror for ongoing fusion. The method is also applicable for advanced, aneutronic reactors, such as p-$^{11}$B. Show Chinese abstract

Abstract: 磁约束聚变反应堆会产生必须去除的灰烬粒子以实现高效运行。 建议使用自共振（非谐运动与线性调频驱动之间的连续相位锁定）从磁镜中去除灰烬粒子，磁镜是最简单的磁约束配置。 通过引导中心近似建立了受驱摆的类比。 对$\alpha$粒子（DT聚变的副产品）进行了完整的三维动力学模拟，结果与近似的1D模型一致。 使用蒙特卡洛模拟对初始条件的相空间进行采样，以量化该方法的效率。 DT燃料粒子超出线性调频驱动的带宽，因此在镜中停留以继续聚变。 该方法也适用于先进的、无中子的反应堆，例如 p-$^{11}$B。
