论文摘要
我们研究了电离辐射对许多光学清晰的环氧树脂的波长190--1100〜nm的光传输的影响。我们发现，传统的，可商购的光学环氧树脂的透射显示出$ 1 \ times10^{12} $ 〜mips/cm $ $ $^2 $的暴露量显着降解。随着剂量的增加，光传输的降解从低剂量的最短波长发展到更长的波长。在厚0.1 〜mm的环氧关节中，我们观察到，对于传统光学环氧树脂的波长，超过5％的光损失了。我们的研究已经确定了一种光学清晰的环氧树脂，该环氧树脂几乎没有降解的辐射暴露，最高$ 5.9 \ times 10^{14} $ 〜mips/cm $ $^2 $（$ \ of 220 $ 〜kgy）。
We study the effect ionizing radiation has on light transmission in the wavelength range 190--1100~nm for a number of optically clear epoxies. We find that the transmittance of traditional, commercially available, optical epoxies show significant degradation for exposures of $1\times10^{12}$~MIPs/cm$^2$. Degradation of light transmission progresses from the shortest wavelengths at low doses to longer wavelengths as the dose increases. In epoxy joints that are 0.1~mm thick, we observe that more than 5\% of the light is lost for wavelengths less than 400~nm for traditional optical epoxies. Our studies have identified an optically clear epoxy that shows little degradation for radiation exposures up to $5.9\times 10^{14}$~MIPs/cm$^2$ ($\approx 220$~kGy).
