Description
Precise magnetic field measurement of undulators is a cornerstone in optimizing synchrotron radiation facilities. This study introduces a position-sensitive Detector (PSD)-based system aimed at enhancing the accuracy of point measurements using Hall probes. By focusing on the challenges of positional deviation and misalignment, the system improves the precision of magnetic field data critical for undulator performance.
The system utilizes PSD technology to achieve high-resolution detection of the transverse coordinates of Hall probes. Real-time feedback mechanisms are integrated to correct the guide rail straightness and mitigate angular deviations during scanning, thereby reducing systematic errors in magnetic measurements. The approach emphasizes robustness and adaptability to standard undulator configurations, ensuring consistency across diverse measurement setups.
The innovations address common challenges in conventional Hall probe methods, such as mechanical instability and positional drift. These advancements contribute significantly to achieving tighter tolerances in undulator magnetic field characterization, enabling higher brilliance and more precise control in synchrotron radiation applications.
