Particle accelerator beam bending magnet

Abstract

The invention discloses a particle accelerator beam bending magnet, comprising main magnetic poles (1), main coils (2), guiding magnetic poles, guiding coils, upper, lower, left and right magnetic yokes, and multiple charged particle beams with properly different energy or particle types, which form a main magnetic field and a guiding magnetic field component; the multiple charged particle beams with properly different energy or particle types enter the bending magnet from different directions, and combined into a beam with the same track and direction after passing through the bending magnet;the main magnetic poles (1), main coils (2), guiding magnetic poles and guiding coils are used in an upper and lower paired manner, a certain gap is reserved between the upper and lower magnetic poles in each pair, a vacuum pipe is installed in the gap, and the beam can pass through the vacuum environment in the vacuum pipe. According to the particle accelerator beam bending magnet provided by the invention, the effect that the multiple beams are combined into one beam is achieved, the domestic blank is filled, and the long-term difficult problem that the particles with the same type and thesame energy cannot be combined into the same beam due to the same bending radius is solved.

Description

Technical field [0001] The invention relates to the technical field of particle accelerators, in particular to a particle accelerator beam deflection magnet. Background technique [0002] When the beam generated by the particle accelerator needs to be deflected, a deflection magnet is usually used, and the magnetic field generated by energizing the deflection magnet can deflect the charged particle beam. The deflection magnet generally uses pure iron material to make the excitation core, which is the magnetic pole of the deflection magnet; uses pure iron or low carbon steel material to make the yoke (peripheral magnetic circuit); the magnetic field generated in the gap between a pair of magnetic poles is used as a charged The particle beam deflects the magnetic field. [0003] In actual scientific research and production, sometimes it is desirable to deflect multiple charged particle beams generated by accelerators and merge them into one beam. However, the existing deflection ma...
