Magnetic Field Measurement System for the Undulator of NSRL Phase II Project

A Hall probe magnetic field measurement device is used to measure the undulator of NSRL Phase II Project, and it can be used to conduct on fly measurement of the magnetic field. A twodimensional automeasurement system has been developed, which includes a machine tool with a motion range of 3 500 mm, and a control system. The distribution of the undulator field is obtained by Hall probe scans to measure the undulator, and the results are analyzed.
