Principle Analysis Between Gun System and Interlock in Varian C-Series Accelerator and Typical Cases
摘要
Abstract
The triode(grid control)electron gun system adopted by Varian C-Series high-energy linear accelerator has a high failure rate and difficulty in solving,which is mainly manifested by unstable dose rate and even unable to emit the beam and report the GFIL gun filament interlock.In this study,Clinac iX,the representative of iX platform,was taken as an example,by analyzing the working principle of the gun control system in detail in combination with typical cases and technical drawings,also the process and direction of signal processing inside and between several key modules such as power supply circuit and gun drive,found the crux of the problem and the components are dealt with to solve the problem,which provides solutions and methods for engineers to solve the similar problems of C series and even the accelerator of a new generation of high-end technology platform with high circuit integration and digitalization.关键词
