Embodiment Construction

[0042] 1. Basic structure of high-energy circular accelerator. Such as figure 1 As shown, a circular accelerator is generally composed of a plurality of magnet assemblies 1 that periodically generate twisted orbits and a high-frequency cavity 2 , and the high-frequency cavity 2 is arranged in a long drift section 3 between the magnet assemblies 1 . The energy-injected particles 4 enter the inner orbit of the accelerator, perform spiral motion under the magnet deflection of the magnet assembly 1, continuously obtain energy gain through the high-frequency cavity, and finally move to the outer orbit of the accelerator to extract energy. It is to draw energy particles 5 .
