Abstract

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.
