摘要
从结构设计和真空获得两方面介绍了HIRFL-CSR磁元件真空室样机的研制过程,给出了力学计算和实验结果。样机达到了10-10Pa的超高真空度,研制结果表明HIRFL-CSR工程大型超高真空系统获得6×10-9Pa的设计指标是可行的。
The development process of the vacuum chamber prototype placed in magnetic field was introduced for both its structure design and ultra-high vacuum acquisition, with relevant mechanical analysis and experimental results given. The UHV degree of 10^(-10) Pa was acquired in the prototype of vacuum chamber, which means that a vacuum degree of 6×10^(-9) Pa is available in designing large-size vacuum system for HIRFL-CSR project.
