| 摘 要： | 如何提高第一镜防护效果是目前托卡马克装置急需解决的问题之一,防护挡板是减轻第一镜表面杂质再沉积的很有效方法.为了研究挡板的防护效果,根据HL-2A装置的具体情况,采用蒙特卡罗方法建立了粒子在第一镜上再沉积的物理模型,模拟了不同情况下粒子在第一镜上的再沉积情况,包括无挡板情况和加锥形挡板情况.和实验结果进行了比较,从而验证了该模型的正确性.这为有效改善第一镜防护效果提供了理论依据.关键词：第一镜再沉积挡板蒙特卡罗方法

| Abstract: | How to improve the protective effect of the first mirror is urgent for tokamaks at present. Buffer is one of the efficient methods to reduce the impurity redeposition on the first mirror. In order to study the protective effect of the buffer, the physical model of the particle redeposition on the first mirror is established with the Monte Carlo method on the basis of the parameters and experiments of the HL-2A tokamak. Particle redepositions on the first mirror are simulated under different conditions, including the cases without buffer and with cone buffer. The simulation results match well with the experimental results. The accuracy of the model is verified, and the simulation is efficient for providing theoretical basis for the protection of the first mirror. |
