Technical Field

The invention belongs to the technical field of particle acceleration, and particularly relates to a synchronous particle acceleration method and device.

Background

A linear accelerator generally refers to an accelerator that accelerates particles by a high-frequency electromagnetic field while the movement locus of the accelerated particles is linear. A high-frequency linear accelerator, simply called a linear accelerator, refers to a device for accelerating charged particles with a high-frequency electric field distributed along a linear trajectory.

The method can be divided into an electron linear accelerator, a proton linear accelerator, a heavy ion linear accelerator, a superconducting linear accelerator and the like according to the types of accelerated particles, the prototype concept of the linear accelerator is firstly proposed by british scientist g.ising in 1924, and he proposed a design pattern of the linear accelerator in an article named as 'principle of method for generating high-voltage polar tunnel rays'. According to the g.ising article, a linear accelerator consists of a straight vacuum tube and a series of perforated metal drift tubes. The acceleration of the particles is accomplished by a pulsed electric field between adjacent drift tubes, and the synchronization of the electric field and the particles is achieved by a time delay of the length of the transmission line between the voltage source and the respective drift tube.

The traditional linear accelerator adopts a linear acceleration method to realize particle acceleration, and the acceleration of point-carrying particles to higher energy requires a larger length. The synchronous accelerator realizes the cyclic acceleration of particles by adopting a circular cyclic acceleration method, and can effectively improve the utilization rate of the system.
