摘要

用geant4模拟1.2MeV电子辐射穿透不同材料和厚度的屏蔽窗后在光纤中的能量沉积值，比较光纤的最大能量沉积值，最后选择厚度分别为1mm、2mm、3mm的铜作为屏蔽。实验得到了光纤辐射诱导衰减曲线，建立了光纤辐射诱导衰减模型，为光纤辐射传感提供了理论依据。

Fiber radiation-induced attenuation sensing design based on geant4 simulation

Simulate the energy deposition value of the 1.2MeV electron radiation in the fiber after penetrating the shielding window of different materials and thicknesses with geant4, compare the maximum energy deposition value of the fiber, and finally select the copper with the thickness of 1mm, 2mm, 3mm as the shielding. The fiber radiation-induced attenuation curve is obtained experimentally, and the f radiation-induced attenuation model is established to provide a theoretical basis for fiber radiation sensing.
