摘要
双晶单色器第一晶体热变形问题是同步辐射光源的光束线设计制造关键技术之一。本文以减少晶体热变形为研究目的,分析了同步辐射双晶单色器第一晶体热变形的原因,阐述了冷却结构的原理,并采用有限元方法对这种机构进行模拟分析,结果表明,此种机构能较大幅度降低晶体的热变形。
An inportant technology of synchrotron radiation beam lines is how to solve thermal distortion of the 1st crystal of monochrotron. In this paper, we propose a new structure to reduce the thermal distortion. Simulation analyses were made using finite element method to analyze two types of water cooling structures. It was concluded that the cooling structure could decrease greatly the thermal distortion.
