| 摘 要： | 利用磁谱仪得到不同能量的单能电子束,让这些电子束穿过不同厚度的铝膜,研究不同能量的电子在铝膜中的吸收系数和能损,得出吸收系数与电子能量的经验公式,与已有的吸收系数经验公式进行了比较,测量到的能损和Fluka软件模拟计算的结果进行了对比,观察到它们之间都能够较好地符合。说明该实验测量的数据和得到的质量吸收系数公式是可靠的,对β射线的防护具有重要参考价值,Fluka软件能够用于较高能量电子能损的计算。

| Abstract: | The differently single energy electron beams are obtained by magnetic spectroscopy. When they pass through the different thickness Aluminum foil, the absorption coefficient and energy loss are studied,then experimental formula about absorption coefficient with electron energy is obtained in comparison with the previous formula. The measured energy losses are also compared with those of Fluka software calculation. It is observed that they are agreeable with each other. It is indicated that the experimental data and the fitted formula about mass absorption coefficient are believable. It is of importance for protection of β ray. Fluka software can be used for the calculation of energy loss for higher energy electron. |
