北京自由电子激光摇摆磁铁场分布测量装置

WIGGLER MAGNETIC FIELD DISTRIBUTION MEASURING SYSTEM FOR BEIJING FREE ELECTRON LASER

摘要: 我们设计加工了一套测量摇摆磁铁整体场分布的测量装置,并对北京自由电子激光(BFEL)摇摆磁铁进行了实际测量,定态测量误差优于1×10^-4,动态测量误差5×10^-4。

Abstract: A system used to measure Beijing Free Electron Laser(BFEL)wiggler magneticfield distribution is described.The system’s measuring error in fixed state and moving state arel×10^-4 and 5 × 10^-4, respectively.
