Light guide illumination and image acquisition system in accelerator radiation protection building aisle

Abstract

The invention discloses a light guide illumination and image acquisition system in an accelerator radiation protection building aisle. The system comprises a linear electron accelerator radiation protection building which is used for protecting the radiation of an accelerator beam center; and a super-strong spotlight which emits high-intensity light, wherein the light is guided to the center of abeam by rotating and adjusting a mirror surface light guide plate and fixing the mirror surface light guide plate, so that the light guide illumination of the center of the beam is realized. A protection hole is formed in the corner of a protection building aisle and used for installing a high-definition video collector, the influence of radiation on the collector is greatly reduced, and finally the real-time working state of a beam center is collected through a mirror reflection plate. The whole system is symmetrically distributed on channels on the two sides with the beam center as the central axis. According to the scheme, the problem that lighting and video electronic equipment cannot normally work for a long time in a high-intensity radiation environment of an accelerator beam centeris solved.

Description

technical field [0001] The invention relates to the technical field of linear electron accelerator protection, in particular to a light guide lighting and image acquisition system for accelerator radiation protection building labyrinths. Background technique [0002] During the irradiation sterilization process of industrial linear electron accelerators, the core is to irradiate the goods through the beam center (irradiation window). At this time, the real-time working status of the beam center (irradiation window) area needs to be accurate. Collect and transmit to the large screen of the control center. However, the central area of ​​the beam is a high radiation dose area, and any electronic devices will not work normally. The special lighting fixtures will be damaged by high dose radiation after only working for a few days. The lifespan is not long and needs to be replaced regularly, and the anti-radiation lamps are expensive, and the video collector also has the same pro...

Problems solved by technology

However, the central area of ​​the beam is a high radiation dose area, and any electronic devices will not work normally. The special lighting fixtures will be damaged by high dose radiation after only working for a few days. The lifespan is not long and needs to be replaced regularly, and the anti-radiation lamps are expensive, and the same problem exists in the video collector

Insufficient light in the labyrinth makes it impossible to collect the real-time working status of the beam center
