Accelerator tubes and magnetrons play important roles in accelerator technology, especially in medical linear accelerators. The following is a detailed explanation of both:
Acceleration tube

Definition and Function:

Accelerator tube is a device used in accelerators to accelerate charged particles such as electrons, protons, etc.

It accelerates charged particles to high speeds through the action of electric or magnetic fields.


characteristic:

The design and structure of acceleration tubes vary depending on the type and energy requirements of the accelerating particles.

In medical linear accelerators, the accelerator tube is one of the important components for generating high-energy electron beams or X-rays.

Magnetron

Definition and Function:

Magnetron is an electric vacuum device used to generate microwave energy and is one of the core components of accelerators.

In medical linear accelerators, the magnetron serves as a microwave source, generating high-power microwaves to drive electron acceleration.


Structure and principle:

The magnetron is composed of a ring-shaped cavity chain connected at the beginning and end, in which the electron beam rotates.

It is a standing wave resonant cavity chain, in which electrons obtain tremendous kinetic energy from an external power source in the deceleration phase, which is converted into microwave energy under the action of a high-frequency field.

Application in medical linear accelerators:

High power magnetron for radiotherapy is one of the core components of medical linear accelerators, used to generate radiation sources and achieve radiotherapy.

It has the characteristics of high technical content, high value, and easy wear and tear, which are crucial for the operation level and performance of accelerators.

Market and Trends:

According to market reports, with the increasing number of cancer patients worldwide and in China, the demand for medical linear accelerators continues to grow, driving the demand for high-power magnetrons.


In the early days, China's demand for medical linear accelerators relied on imports, but in recent years, with the promotion of national policies, related technological bottlenecks have been continuously broken through, gradually achieving independent development.

In the "14th Five Year Plan" for the development of the medical equipment industry jointly issued by the Ministry of Industry and Information Technology and ten other departments in China, high-power magnetron tubes for radiotherapy are included in the key component list for key research and development, promoting the development of their independent production.
In summary, the accelerator tube and magnetron each have their unique functions and roles in accelerator technology, and together constitute an important component of the accelerator system. In medical linear accelerators, they are key components for achieving radiation therapy.
