用于测量高能γ射线的三晶电子对谱仪的研制

Development of Three-crystal Electron-pair Spectrometer for Detecting High-energy γ Ray

  • 摘要: 为解决高能γ射线的准确测量问题,本文基于自主研发的闪烁晶体探测器研制了一套三晶电子对谱仪,测量了56Co放射源1.5 MeV以上γ射线的双逃逸峰能谱。与使用单个LaBr3探测器所测能谱相比,三晶电子对谱仪有效降低了峰与连续本底的比值。本文研究结果为准确测量加速器共振核反应(p,γ)及激光康普顿散射(LCS)产生的高能γ射线奠定了技术基础。

     

    Abstract: In order to solve the problem of accurate measurement for high-energy γ ray, a set of three-crystal electron-pair spectrometer was developed based on the self-developed scintillation crystal detector. The double-escape peak energy spectrum above 1.5 MeV γ ray of 56Co source was measured. The three-crystal electron-pair spectrometer can effectively reduce the ratio of peak to continuous background compared with LaBr3 detector. It lays the technical foundation for accurate measurement of high-energy γ ray from nuclear resonance reaction (p,γ) and laser Compton scattering (LCS).
