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] The embodiments of the present invention will be described in detail below with reference to the drawings.
[0013] reference 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 two upper and lower layers.
[0014] The upper layer includes an accelerator room 21 and a control room 20, which are constructed of ordinary masonry structure 18. The door 23 of the accelerator room 21 is an ordinary light-weight door without radiation protection function, rather than a very heavy shielded door as required in the prior art. An accelerator 1 is installed inside the accelerator room 21. A shield 22 is installed on the outside of the accelerator 1, including the periphery and the top. The shield 22 is made of heavy metal materials such as steel, lead or tungsten. It has a radiation protection f...
