【摘要】 真空系统在EAST全超导托卡马克装置中是非常重要的组成部分,它主要由内真空室抽气系统和外真空室抽气系统组成。内真空室抽气系统主要由主抽系统、偏滤器抽气系统、低杂波抽气系统组成,主要为等离子体的稳定运行提供清洁的超高真空环境;外真空室抽气系统主要由主抽系统、电流引线段抽气系统及低温阀箱抽气系统组成,主要为超导磁体的正常运行提供真空绝热条件。EAST真空抽气系统经过三轮物理实验的不断改造和完善,目前基本满足了等离子体物理实验的需要。更多还原

【Abstract】 The vacuum pumping system as a very important integral part of EAST is mainly composed of the inner and outer vacuum pumping subsystems.The former mainly includes three pumping systems,ie.,the major one and the other two for flow diverter and lower hybrid wave part,separately.It provides and maintains the clean and high vacuum environment for steady plasma operation.The latter keeps superconducting magnet adiabatic,which is basically made up of the three pumping systems for cryostat vacuum vessel,current lead tanks and cryogenic valve box,separately.After the reform and improvement in three rounds of physical test,the EAST vacuum pumping system can meet the requirements for further plasma physical experiments nowadays.更多还原
