AI Technical Summary

Technical Problem

Traditional electron linear accelerators have large radio frequency power sources that consume a lot of energy and have limited lifespan. This affects the stability of microwave power and makes it difficult to achieve high-precision, traceable, and intelligent irradiation control.

Method used

Modular solid-state power amplifiers are used to replace vacuum electronic devices, and digital signal processing technology is combined to achieve rapid and precise control of microwave power. Beam parameters and dose distribution are controlled through real-time monitoring and closed-loop feedback.

Benefits of technology

It achieves high-energy and stable electron beam current, ensuring the accuracy of the irradiation process and the uniformity and traceability of dose distribution, reducing system failure rate and maintenance costs, and promoting the miniaturization and integration of equipment.

Abstract

This application relates to an electron linear acceleration and irradiation method based on a solid-state power source, comprising: the extracted electron beam passes through the guiding and focusing elements in the beam transmission system and reaches the irradiation area; along this path, key parameters of the electron beam are monitored in real time using a beam diagnostic device, including at least beam energy, current intensity, and beam spot position information; the material to be irradiated is placed in the irradiation area and receives scanning irradiation from the electron beam; simultaneously, dose monitoring sensors deployed in the irradiation area or within the material are used to acquire absorbed dose rate or cumulative dose distribution information in real time; throughout the acceleration and irradiation process, the central controller synchronously records timestamp-correlated historical data of beam parameters, power source adjustment commands, dose monitoring data, and material identification information to obtain a complete and traceable electron beam irradiation process archive.
