There is a close relationship between the pre injector and the electron linear accelerator. As an important component of the electron linear accelerator system, the pre injector's main function and function is to provide a stable and high-quality electron beam source for the accelerator. The following is a detailed explanation of the relationship between the pre injector and the electron linear accelerator:



The generation of electron beam: The electron gun in the pre injector is the starting point of electron beam generation. The electron gun emits electrons by heating the cathode material and forms an electron beam under the action of a high-voltage electric field. This electron beam is then further focused and shaped by the beam focusing system inside the pre injector to ensure its quality meets the requirements of the subsequent acceleration process.

Pre acceleration of electron beam: The pre injector not only generates the electron beam, but also is responsible for preliminary acceleration. By precisely controlling the electric and magnetic fields, the pre injector can accelerate the electron beam to a certain energy level, preparing for further acceleration in the electron linear accelerator.

Matching and transmission: Good matching and transmission need to be achieved between the pre injector and the electron linear accelerator. This means that the electron beam generated by the pre injector needs to match the requirements of the electron linear accelerator in terms of energy, beam intensity, beam spot size, etc., to ensure that the electron beam can smoothly enter the accelerator tube and be effectively accelerated. At the same time, an efficient transmission system, such as transmission lines or microwave transmission cavities, is required between the pre injector and the electron linear accelerator to ensure the stability and quality of the electron beam during transmission.



Control system and synchronization: The pre injector and electronic linear accelerator usually share a control system to ensure synchronization and coordination between the two. The control system is responsible for monitoring and adjusting various parameters of the pre injector and electron linear accelerator, such as voltage, current, magnetic field strength, etc., to ensure that the generation, acceleration, and transmission process of the electron beam can proceed according to the predetermined program.

Stability and reliability: The performance of the pre injector directly affects the stability and reliability of the electron linear accelerator. A well-designed and high-performance pre injector can generate high-quality and stable electron beams, thereby improving the performance and reliability of the entire accelerator system.

There is an inseparable relationship between the pre injector and the electron linear accelerator. The pre injector provides a stable and high-quality electron beam source for the electron linear accelerator, and ensures that the electron beam can smoothly enter the accelerator tube and be effectively accelerated through precise control and matching. Meanwhile, the performance of the pre injector directly affects the stability and reliability of the entire accelerator system.
