一种测量辐射加工用加速器电子束能量的方法

A measurement method for electron beam energy of industrial electron accelerators

根据射程法原理，在上海二级标准剂量学实验室对辐射加工用加速器电子束能量的测量 方法进行了实验研究，并在３个辐射工厂对３台３ＭｅＶ、２０ｍＡ高频高压型加速器的电子束进行 了能量测定。结果表明，在１－３ＭｅＶ能量范围内，能量测定准确度优于± １０％。

Cover glass was used to measure the electron range and energy. The experimental study was done at Shanghai Standard Dosimetry Laboratory. Then the election bean energy of three industrial electron accelerators for radiation processing was measured. R.D.Evans equation was chosen among several empirical equations for the energy measurement. The results show a linear range-energy relationship that is applicable from 1 to 3MeV, with ± 10% accuracy.
