Problems solved by technology

The inserted magnet will cause a sharp increase in the capacitive load of the high-frequency accelerating cavity. In this case, in order to achieve the same accelerating electric field, the power fed into the high-frequency accelerating cavity will increase by ten to dozens of times, which will make the accelerator The construction cost of the accelerator increases sharply, and the heating problem caused by high power will make the operation of the accelerator more difficult

Abstract

The invention relates to a linear accelerator. The linear accelerator comprises an acceleration cavity shell, a core pipe and at least three tandem four-pole magnets, wherein the acceleration cavity shell is located in an acceleration cavity and is connected with the inner wall of the acceleration cavity; the core pipe is located in the acceleration cavity shell and allows particle beams to pass,and the four-pole magnets are located in a magnet cavity shell, are used for focusing the particle beams and comprise central through holes, and the core pipes penetrate through the central through holes. A synchronous accelerator is characterized in that the linear accelerator is taken as an injector of the synchronous accelerator.

Description

Technical field [0001] The invention relates to the related field of particle accelerators, in particular to a linear accelerator and a synchrotron. Background technique [0002] An accelerator is a device that increases the kinetic energy of charged particles. It can be used in nuclear experiments, radioactive medicine, radiochemistry, radioisotope manufacturing, and non-destructive testing. The current mainstream heavy ion proton accelerators are divided into three categories, namely linear accelerators, cyclotrons and synchrotrons. Linear accelerators and cyclotrons are suitable for low and medium energy protons and heavy ions, and can be used for medium and low energy material irradiation and ion implantation; synchrotrons are suitable for higher energy protons and heavy ions, and are generally used for cancer radiotherapy or medium High-energy material irradiation field. The cyclotron has very low beam transmission efficiency due to its own structural limitations. The lin...
