中文摘要：

作为国家大科学工程中性束注入装置的重要组成部分,EAST-NBI多功能测试室主要用于对中性束注入装置各个部件的性能测试与优化;同时可模拟托卡马克入口环境和压力条件,进行模拟注入试验;并可功能扩展以用于多种科学领域的研究。多功能测试室内部主要包括一个圆柱型低温泵、一个＂V＂字型的功率测量靶和一个用于放置测试试样的测试平台。通过对多功能测试室的功能需求、工作原理以及主体结构展开设计研究,结论表明该测试室对于不同工况的测试均能满足测试需求。

英文摘要：

As an important component of National Big Science Project EAST-NBI,EAST-NBI multi-function test tank is mainly used for performance test and optimization of each component of NBI.The test tank simulates the environment of entrance and pressure between Tokomak and NBI and the experiment of neutral beam injection and can be used in research of different fields of science.The test tank contains a cylindrical cryopanel,a ‘V’shaped calorimeter and a test bed for placing the sample.Based on the function of the multi-function test tank requirements,as working principle and main structure design research,the results indicate that the test tank can meet the test requirements of different working conditions.
