Electron irradiation accelerator device is a multi discipline comprehensive industrial production equipment, involving high voltage, high vacuum, high pressure, electronics, computer, microwave technology, automatic control technology, mechanical design and processing, beam current measurement, dosimetry, radiation protection etc.. Any local problems will affect the normal operation of the accelerator affecting the production, so the quality must be excellent accelerator. Application of accelerator device types and different application accelerator in radiation processing device only type high-voltage electron irradiation accelerator and resonant type electron irradiation accelerator two. The two accelerator device and other applications of accelerator, each with their structure, performance characteristics and different scope of application. But all have:

1 electron gun;

2 accelerator host, including accelerating electric field system, controlling magnetic field system, vacuum system;

3 beam extraction application device, including a scanning device, a beam extraction device or a target device;

4 control system.

Modern scale of production conditions, accelerator has the advantages of compact structure, simple operation, safe and reliable, work steady state, long period operation, beam energy and flow adjustment, easy maintenance, can be in any need of startup and shutdown, and accelerator to adapt to the requirement of factory buildings, and production line equipment matching etc.. Because the modern electron irradiation accelerator device has the conditions for these functions, can realize automation production scale, the radiation processing industry obtained the widespread application and development.

Usually I will according to the energy electron irradiation accelerator is divided into energy, energy, energy third.

1 low energy electron irradiation accelerator

In the energy range 100KeV300KeV beam power flow characteristics of a few Kw250Kw is not accelerating tube and scanning device, self shielding, models for the electron curtain accelerator. Mainly used for coating curing, film and sheet radiation processing, flue gas purification, etc..

2 energy electron irradiation accelerator

Energy range 0.3MeV5MeV beam power a few Kw500Kw features are the main engine for a cylindrical scanning accelerator. Main models have to the meters (high voltage) type, insulating core transformer, high pressure transformer, resonant transformer type, high frequency cavity single pulse type accelerator. In electron irradiation accelerator are widely applied, mainly used for radiation processing of wire and cable, foam materials, heat shrinkable materials, construction materials, such as rubber.

3 high energy electron irradiation accelerator

The energy range of 5MeV10MeV beam power of several Kw over 300Kw is characterized by scanning electron beam accelerator, can be converted to X ray. Main models are irradiated with electron linear accelerator, a plum blossom petal (the rhodotron electronic accelerator and 5MeV above to the M accelerator. Mainly used for medical radiation disinfection, food preservation, raw materials for aerospace composite insecticidal, radiation curing etc
