[0002] Cyclotron is a kind of device for accelerating charged particles, and is widely used in nuclear physics, medicine and industry and other fields.

Specifically, cyclotron is composed of two D-shaped metal boxes and an electric field slit. The period of the alternating voltage applied between the electric field slit region is the same as the particle motion period. When charged particles move between the two D-shaped metal boxes, they are accelerated by the uniform electric field in the middle; when moving in the upper and lower D-shaped metal boxes, they only do uniform circular motion under the action of Lorentz force,
