| 摘 要： | 为了更有效地测量用于上海同步辐射光源波荡器的积分场误差，在已有的伸展线磁测系统的基础上研制了一套翻转线圈磁测系统，该系统的运动控制、数据采集和数据分析处理均可自动完成。在利用这套磁测系统测量3.4×10-6 T·m磁场积分时获得高于1×10-6 T·m的测量精度，初步的实验结果表明这套波荡器积分磁场测量系统具有测量精度好、速度快的特点，与已有的伸展线磁测系统、平移线圈磁测系统和霍尔点测系统相比，它更适合于测量波荡器的一、二次场积分和多极场分量。

| Abstract: | In order to characterize the undulators at Shanghai Synchroton Radiation Facility(SSRF), a flipping coil magnetic field integral measurement system for the measurement of both first and second magnetic field integral distributions and integrated multipole errors in undulators has been developed recently.The system can automatically finish motion control, data acquisition and data analysis. The main features of this system are their high speed of measurement, high precision. Initial results demonstrated that the system achieves a system measurement precision of 1×10-6 T·m in a field integral measurement of 3.4×10-4 T·m.The system is efficient enough to finish the measurements of magnetic field integral in undulators. |
