摘要

高能光子源（HEPS）第一阶段的批量生产已接近尾声。目前已制造出 6 个 CPMU（低温永磁起动器），其中 4 个已成功完成磁场调谐。为确保辐射性能，HEPS 的 CPMU 执行严格的相位误差协议。此外，低温下的收缩特性也会导致冷却后的相位误差减小。在 CPMU 调试过程中，发现并研究了一种预测从室温到低温磁场误差变化的技术，本文将对此进行演示。

Study on the influence of gap dependent error on the cryogenic permanent magnet undulator performance

The mass production of the first stage of HEPS (High Energy Photon Source) is approaching its final stage. 6 CPMUs (cryogenic permanent magnet undulators) have been manufactured, with four successfully finalizing the tuning of the magnetic field. To ensure radiation performance, HEPS's CPMUs enforce stringent phase error protocols. Moreover, the contraction properties at cryogenic temperature lead to a decrease in phase error after cooling. In the process of CPMU commissioning, a technique for forecasting the change of magnetic errors from room to cryogenic temperature was discovered and studied, as will be demonstrated in this paper.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
