Abstract

The invention relates to a microwave electron accelerator. The microwave electron accelerator comprises a magnetron, a waveguide system, an accelerating cavity, a magnet system and an electronic generator. The magnetic field strength values of the magnet system are small in the middle and large on the periphery of the accelerating cavity. The effective electric field component of the microwave in an accelerating zone of the accelerating cavity is perpendicular to the direction of a magnetic field. Electrons are under the action of the magnetic field in the accelerating cavity to perform cyclotron motion, and the cyclotron frequency is identical to the microwave frequency to form resonance acceleration. The microwave electron accelerator accelerates the electrons in a vacuum chamber with the magnetic field through the microwave to achieve the energy of tens of kilo electron volts to hundreds of kilo electron volts so as to use the electrons for generating X-rays or sterilization. The accelerator has the advantages of being simple, compact and reliable in structure and capable of producing high electron beams and has continuous working life of more than one year to reach the condition of long-time running of, industrial production equipment.

Description

technical field [0001] The invention relates to the technical field of electron accelerators, in particular to a low-energy microwave electron accelerator utilizing microwaves. Background technique [0002] Electron accelerator is a widely used equipment, which is mainly used in industrial flaw detection, safety inspection, medical inspection, medical treatment, radiation sterilization and other fields. Among them, in the field of low-energy detection, electron accelerators are the most widely used, but the common low-energy electron accelerators commonly used at present usually adopt the method of high-voltage acceleration, and the accelerator has the problems of low electron current strength and low efficiency. Disadvantages such as high price and easy high-voltage ignition. [0003] For example, the University of Science and Technology of China applied on January 16, 2012, the application number is 201210013051.9, and the name of the invention is a high-precision DC UHV ...
