1、 Introduction

With the increasing prosperity of global trade and the rapid development of the logistics industry, the transportation volume of large vehicle containers has been increasing year by year. In order to ensure logistics safety and prevent illegal transportation of prohibited and dangerous goods, container security inspection technology is particularly important. As one of the important means of container security inspection, X-ray imaging system's technical level and detection effect directly affect the efficiency and accuracy of security inspection work. Electron cyclotron and electron linear accelerator, as key components of X-ray imaging systems, are of great significance for improving imaging quality and detection efficiency. This article will provide a detailed introduction to the principles, characteristics, and applications of electron cyclotron and electron linear accelerators in X-ray imaging systems for large vehicle containers.

2、 Application of Electron Cyclotron in X-ray Imaging Systems

Electron cyclotron is a low-energy accelerator that utilizes a constant magnetic field and a high-frequency electric field to accelerate electrons. In the container X-ray imaging system, an electron cyclotron generates X-rays by producing high-energy electron beams that collide with metal targets. Due to the high energy resolution and stability of electron cyclotrons, the X-rays they produce have high penetration and imaging quality.

The principle of electron cyclotron

The electron cyclotron is mainly composed of a magnetic field system, a high-frequency electric field system, and a vacuum chamber. Under the action of a constant magnetic field, the time for an electron to wrap around it increases with the increase of energy. Through the action of a high-frequency electric field, electrons can obtain a certain amount of energy increment every time they orbit, thereby achieving electron acceleration. When an electron is accelerated to the required energy, it is pulled out of the circular orbit, causing it to collide with the target and produce X-rays.

The characteristics of electron cyclotron

Electron cyclotron has the characteristics of energy variability over a wide range, low energy dispersion, small focal size, high beam intensity, and good beam collimation. These characteristics make electron cyclotrons have broad application prospects in container X-ray imaging systems.

The Application of Electron Cyclotron

In container X-ray imaging systems, electron cyclotron accelerators are mainly used to generate high-energy X-rays. Due to the high energy resolution and stability of electron cyclotrons, the X-rays they produce have high penetration and imaging quality. By adjusting the parameters of the electron cyclotron, different energy levels of X-ray output can be achieved to meet the security requirements of different materials and items. In addition, electronic cyclotron accelerators can also be combined with other imaging technologies, such as CT imaging technology, to achieve more precise detection of the internal structure of containers.

3、 The application of electron linear accelerator in X-ray imaging system

An electron linear accelerator is a resonant accelerator that uses a microwave electric field to accelerate electrons along a linear orbit to higher energy. In container X-ray imaging systems, electron linear accelerators also generate X-rays by producing high-energy electron beams that collide with metal targets. Compared to electron cyclotron accelerators, electron linear accelerators have higher energy and a wider energy range.
The principle of electronic linear accelerator

The electron linear accelerator utilizes high microwave power to establish a longitudinal electric field in the traveling wave and standing wave acceleration structures to accelerate the electron beam. According to the type of microwave, it can be divided into traveling wave and standing wave electron linear accelerators. An electron linear accelerator continuously accelerates an electron beam to a higher energy level, and then collides with a metal target to produce X-rays.
The characteristics of electronic linear accelerators

Electronic linear accelerators have the characteristics of high energy, wide energy range, and good stability. The X-rays generated by it have high penetration and imaging quality, which can achieve detection of deep structures inside containers. In addition, electronic linear accelerators can also achieve fast scanning and imaging, improving the efficiency of security inspection work.

The Application of Electronic Linear Accelerator

In container X-ray imaging systems, electronic linear accelerators are mainly used for fast and efficient security checks of large vehicles and containers. Due to its high energy and wide energy range, it can achieve comprehensive detection of different materials and items. Meanwhile, electronic linear accelerators can also be combined with other imaging technologies, such as dual energy imaging technology, to achieve precise identification of specific substances.

4、 Comparison between Electron Cyclotron and Electron Linear Accelerator

Electron cyclotron and electron linear accelerator each have their own advantages in container X-ray imaging systems. The electron cyclotron has high energy resolution and stability, making it suitable for detecting the fine structure inside containers; Electronic linear accelerators, on the other hand, have higher energy and a wider energy range, enabling comprehensive detection of different materials and items. In practical applications, suitable accelerator types can be selected based on specific needs and scenarios.
