200MeV电子直线加速器隧道内辐射场测量

The Radiation Field Measurement in the 200 MeV Electron Linac Tunnel

对电子直线加速器运行期间隧道内的辐射场进行测量,可以为装置提供重要的参考数据;预测元器件及材料的使用寿命和研究辐射场的开发利用。本文介绍了加速器周围辐射场的特点,论述了丙氨酸(alanine)剂量计的性能和用电子自旋共振测量法进行测量的依据、方法,并分析了用这种方法所得到的结果。

To measure the radiation level in tunnel during a Linac running period, can provide important data to improve the machine, forcast the lives of electronic devices and other materials, exploit the radiation field as well. This paper introduces the properties of the radiation field around Linac, discusses how to measure the radiation level with alanine dosemeter and ESR method, analyses the result of our measurement.
