【摘要】 EAST超导托卡马克试验装置是国家九五大科学工程项目,在2009年度春季物理实验中取得了巨大成功。在本次实验取得巨大成功的同时,偏滤器部件也发现了问题,多处外靶板与Dome间缝隙内挡板熔化被高能粒子击穿,部分挡板后水管被烧坏。本文针对目前EAST实验中遇到的问题,提出了增设石墨瓦结构,形成"V-shape corner"结构的方案。并对新结构对偏滤器抽气系统流导的影响进行了理论计算、数值模拟和优化。这对最终方案的确定提供了理论依据。更多还原

【Abstract】 EAST tokamak device is project a national science project.The experiments on EAST in 2009 spring are very successful,which however bring many problems with divertor components.Some baffling plates between targets and dome melt and were penetrated by energized particles,which broke the pump channel behind.According to these problems,carbon blocks are added and a new structure with V-shape corner is proposed.The influence of the new structure on the divertor pumping system is evaluated by means of theoretical calculation and numerical simulation.The results can provide theoretical basis for the determination of the final scenario.更多还原
