| 中文摘要 | 在 D-T 聚变脉冲γ时间谱测量场合,由于本底低能γ强度大,因此要求探测器对高能聚变γ灵敏度远大于低能本底γ灵敏度。本文在理论分析计算的基础上,提出了基于康普顿效应的散射吸收探测方法,该方法能实现高低能γ灵敏度比值达10~6～10~8,且对高能聚变γ灵敏度为10~(-21)～10~(-16)C·cm~2,其性能指标在一定程度上优于目前使用的基于磁分析器与 Cherenkov 探测器的聚变γ探测方法。; As the intensity of low-energy background gamma-ray is much higher than the fusion high-energy gamma,the detector that used for D-T fusion high-energy gamma diagnosis must be more sensitive to high-energy gamma than the low-energy gamma.Base on theoretical calculation and Monte Carlo simulation,this paper proposes a new method of diagnosing fusion gamma,named“scattering absorption method based on Compton scattering”.The ratio of the sensitivity of fusion gamma to that of the low-energy gamma can reach 10~6 to 10~8 by this new method.The sensitivity of fusion gamma ranges from 10"21 to 10~(-16)C·cm~2.It's better than the traditional method which base on the magnetic analyzer and Cherenkov detector on some aspects. |
