我们描述了一种校准铅玻璃量热计的方法，它不需要已知能量的光束。该技术被用来校准在杰斐逊实验室的radphi铅玻璃量热计。所述技术可应用于任何能够检测介子的全光子衰变（例如π0→2γ、η→2γ或ω→π0γ）的分段电磁量能器。我们还演示了如何将测量的π 0和η介子的2γ质量宽度展开，以提取量热计的单簇射能量和位置分辨函数。
We describe a method for calibration of a lead-glass calorimeter that does not require a beam of known energy. The technique was used to calibrate the radphi lead-glass calorimeter at Jefferson Lab. The technique described can be applied to any segmented electromagnetic calorimeter capable of detecting all-photon decays of mesons, for example, π0→2γ, η→2γ or ω→π0γ. We also demonstrate how the measured 2γ mass width of the π0and η mesons can be unfolded to extract the single-shower energy and position resolution functions of the calorimeter.
