Description
The injector operating within the 3–15 MeV energy range is considered to hold significant potential for various practical applications, with broad prospects demonstrated in scientific experiments and industrial applications. For such typical injectors, the precise measurement of beam quality through a beam diagnosis system is considered crucial. The development of a universal beam diagnosis platform based on magnets has been presented in this paper, with a focus on the design, fabrication, and testing of its core magnetic components—the dipole (D) magnet in the energy spectrum measurement system and the quadrupole (Q) magnet in the emittance measurement system. Based on the system's physical design, key parameters such as magnet uniformity and multipole moments have been considered to ensure the system's precision. The validity of the design has been confirmed by comparing the measured data of the fabricated magnets with simulation results. Through the study and optimization of the D and Q magnets, accurate beam parameter analysis is enabled by the universal magnet-based beam diagnosis system, which supports the optimization of injector performance.
