摘要
本文描述了一种20MeV医用电子直线加速器剂量监察和控制系统。系统由透射式平行板电离室和电路组成。平行板电离室电极厚度<0.05mm,适用于快电子和高能X射线的剂量测量。剂量监测和控制系统有良好的线性。测量结果表明,本系统技术指标达到设计要求,性能稳定可靠。
The dose monitor and control system for electron beam and X ray on a 20 MeV medical linear accelerator is described. The system is composed of a transmission parallel-plate ionization chamber with appropriate electronic circuits. The thin foil electrodes (0.05mm) of the chamber are suitable for dose monitoring and measurement of high energy electron beam and X rays. The experimental results show that this system, with excellent linearity, is stable, reliable and fulfils design requirements.
