Problems solved by technology

All of the above greatly increase the construction cost and take up a large space
In addition, because the accelerator room 14 has very strong radiation rays, the accelerator power source and the auxiliary system 5 are installed in the equipment room 16 outside the shielding wall, and the power delivery device 4 connecting the accelerator 1 and the accelerator power source and the auxiliary system 5 requires Passing through a very thick concrete shielding wall, the longer its length, the greater the power attenuation, which reduces the power efficiency of the entire system and weakens the radiation processing capability of the system

Embodiment Construction

[0012] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0013] refer to figure 2 , which shows a radiation self-shielding high energy electron beam irradiation processing system 200 according to an embodiment of the present invention. The high-energy electron beam irradiation processing system 200 is arranged in upper and lower layers.

[0014] The upper level includes the accelerator room 21 and the control room 20 , which are constructed of ordinary masonry 18 . The door 23 of the accelerator room 21 is an ordinary light door without radiation protection function, rather than a very thick and heavy shield door as required in the prior art. The accelerator 1 is installed inside the accelerator chamber 21 . A shielding body 22 is installed on the outside of the accelerator 1 , including its periphery and top. The shielding body 22 is made of heavy metal materials such as steel, lead or tungsten, has a ...

Abstract

The invention discloses a system (200) for irradiation processing a high-energy electron beam having a self-shielding radiation source. The system comprises an irradiation device and a civil building, wherein the irradiation device comprises an accelerator (1), and a shield (22), an accelerator power source and accessory system (5), a power transporting device (4), a scanning box (3), an electron beam drift tube (2), an article conveyer system (7) and a control system (6) which are arranged on the periphery and the top of the accelerator (1). The civil building comprises an irradiating room (1) provided with the scanning box (3), an article sending maze (13), a control room (20) provided with the control system (6) and an accelerator room (21) provided with the accelerator (1). The irradiation processing system (200) is provided with a self-shielding function for the accelerator (1) so as to greatly save the defending cost of the civil building and conveniently assemble and maintain.

Description
