Description

Abstract Background: A set of high-precision magnetic field measuring system can guarantee the undulator magnetic field optimization and meet the measurement requirements. Purpose: We can operate magnetic field measurement in an enclosed space and construct a set of measuring system to obtain the coordinates of the Hall sensor. Methods: The base is designed using Solid Edge and data acquisition program can be written by LabVIEW. Position sensitive detector(PSD) is used to acquire the exact position coordinates of Hall probe. At last, we create points and plot by MATLAB to analyze the data change. Results: The position measuring system based on PSD accurately reflects the position changes and the fitting curve shows the guide rail variation trend. Conclusion: The measurement accuracy can reach 5 μm. PSD has an advantage over optical system, which can be widely used in measurements of position and small displacement. (authors)
