The design of magnetic field mapping system

The cyclotron is an important device in the field of high-energy physics experiments and radiation medicine, and its performance is directly affected by the uniformity and stability of the magnetic field. In this paper, a Hall sensor-based magnetic field measurement system is introduced to achieve high-precision measurement and real-time monitoring of the magnetic field of cyclotrons. The system realizes the accurate measurement and dynamic analysis of the magnetic field distribution in the cyclotron through the combination of sophisticated mechanical and advanced data acquisition technology and magnetic field reconstruction algorithm. On the basis of full consideration of environmental factors and systematic errors, the measurement results show excellent accuracy and repeatability, which effectively guides the commissioning and optimization of the accelerator.
