The working principle of linear electron accelerators is based on the force of electric field on charged particles, and the electrons are accelerated by continuous linear electric field to reach a high energy state. Its basic structure includes electron gun, acceleration tube, focusing system, deflection system and target. The electron gun generates the electron beam, the accelerator tube accelerates the electron beam to the required energy through a continuous linear electric field, the focusing system ensures that the electron beam remains in focus during the transmission process, the deflection system controls the deflection direction of the electron beam, and finally the electron beam impacts the target to produce various physical effects.

Precision control is another important aspect of linear electron accelerator technology. With the development of computer technology and control theory, the precision control technology of linear electron accelerators has been improved significantly. By using advanced control systems and algorithms, it can achieve accurate control of electron beam energy, position, Angle and other parameters, thus meeting the needs of various complex experiments and industrial applications.

 

Stability improvement

Stability is one of the important indexes of linear electron accelerator technology. In order to improve the stability of linear electron accelerators, researchers have adopted a variety of methods, such as optimizing the acceleration tube design, improving the cooling system, and improving the stability of the power supply. These measures effectively reduce the failure rate and operating cost of linear electron accelerators, and improve their reliability and availability.

Scientific research

Linear electron accelerators are widely used in scientific research. For example, in physics research, linear electron accelerators can be used to produce beams of high-energy particles for the study of fundamental physics such as the structure of atomic nuclei, particle production and decay. In materials science, linear electron accelerators can be used to analyze the composition and structure of materials, revealing the physical and chemical properties of materials. In the field of biomedicine, linear electron accelerators can be used to study the structure and function of biomolecules, providing new ideas and methods for disease diagnosis and treatment.

 

Medical diagnosis and treatment

In the medical field, linear electron accelerators are mainly used for radiation therapy. By precisely controlling the energy, position and Angle of the electron beam, it is possible to achieve precise strikes on tumor cells and reduce the damage to surrounding normal tissues. Compared with traditional radiation therapy, linear electron accelerator has higher accuracy and better therapeutic effect. In addition, linear electron accelerators can also be used for X-ray diagnostic examinations, such as X-ray fluoroscopy, CT scanning, etc., to provide an important diagnostic basis for doctors.

 

Industrial inspection

Linear electron accelerators also play an important role in the field of industrial testing. For example, in non-destructive testing, X-rays generated by linear electron accelerators can penetrate the surface of a material to detect defects and damage inside the material. This method is widely used in the product quality inspection of aviation, aerospace, automobile, machinery and other fields. In terms of food irradiation, the electron beam generated by the linear electron accelerator can be used for food sterilization and fresh-keeping treatment, extending the shelf life and safety of food.
