Magnet measurement using 2D automatic rotation Helmholtz coils
摘要
Abstract
A magnet measurement method using 2D automatic rotation Helmholtz coils has been proposed to improve the measurement efficiency and accuracy of magnets in the research and development of undulators and wigglers. Theoretical analysis reveals that automatic magnet measurement can be achieved merely by 2D automatic rotation mechanism instead of 3D one, which can facilitate the automatic measurement. Such equipment has been developed successfully by using ingenuous 2D rotation mechanism, and has been applied in magnet measurement in SSRF (Shanghai Synchrotron Radiation Facility). The measurement principle and method are given in detail in this work, and the measurement errors are analyzed. This equipment can accomplish measurement of single magnet in 30 s, with the repeatability and accuracy both above 0. 05%.关键词
