Proton and heavy ion irradiation shielding door and use method thereof

Abstract

The invention belongs to the technical field of heavy ion irradiation, and particularly relates to a proton and heavy ion irradiation shielding door and a using method thereof.The proton and heavy ion irradiation shielding door comprises a wall, a guide seat and a door body, the guide seat is installed on the wall, the door body is slidably connected to the lower end of the guide seat, and the proton and heavy ion irradiation shielding door further comprises installation mechanisms arranged on the wall and the door body; the installation mechanism comprises a first protection assembly, a moving assembly and a second protection assembly, the first protection assembly comprises an organ cover and a first stainless steel protective fence, the organ cover is installed on the left side of the door body, the first stainless steel protective fence is installed on the ground, and the first stainless steel protective fence is arranged on the outer side of the organ cover and the outer side of the door body. The proton and heavy ion irradiation shielding door has the beneficial effects that by optimizing the mounting structure of the proton and heavy ion irradiation shielding door, the door body is more convenient and faster to mount and operate, and by additionally arranging the two protection assemblies, high-vigilance protection is conducted on the outer side of the door body.

Description

technical field [0001] The invention relates to the technical field of heavy ion irradiation, in particular to a screen door for proton heavy ion irradiation and a method for using the same. Background technique [0002] Proton heavy ion irradiation center projects generally have various types of production workshops, maintenance and testing workshops, etc., to meet the production, commissioning and production use of proton heavy ion equipment. In order to meet the requirements of safe and reliable installation and commissioning of equipment, and Meet the radiation protection design requirements, ensure that the radiation dose in the area outside the radiation protection wall during the operation of the equipment meets the relevant national safety standards, and meet the personal and equipment safety requirements. [0003] The existing proton heavy ion irradiation screen door design is relatively simple, only considering the radiation safety shielding, lack of a lot of safet...

AI Technical Summary

Problems solved by technology

[0006] Therefore, the object of the present invention is to provide a proton heavy ion irradiation screen door and its use method. By optimizing the installation structure of the proton heavy ion irradiation screen door and adopting the structure of electric translation, in order to ensure the stability and It is safe, durable and reliable. It adopts double tracks and load-bearing rollers as the transmission equipment of the protective door. The rollers are installed at the bottom of the door. The rollers run on the track. The reduction motor gear and rack drive structure, by adding two sets of protective components, provide high vigilance protection to the outside of the door body, which can solve the above problems , in view of the insufficient consideration of safety measures during the installation of proton heavy ion equipment, the design and use of protective doors are not the optimal solution
