论文摘要
我们对电子和黑龙在大型均匀量热计中产生的阵雨进行了Geant4仿真研究。我们发现能量矿床可以表示为轨道长度的线性函数。该线不会通过原点，截距处的能量沉积与入射能量成正比。此外，对于电子和黑龙来说，该线的斜率与入射能无关。量热计的能量分辨率可以用相关线周围的分布来表示，我们发现Pions的$ 19 \％ / \ sqrt {e（\ rm {gev}）} $非常好。
We performed a Geant4 simulation study on showers generated by electrons and hadrons in a large homogeneous calorimeter. We found that the energy deposit can be expressed as a linear function of the track length. The line does not pass through the origin, and the energy deposit at the intercept is proportional to the incident energy. Moreover, for both electrons and hadrons, the slope of the line is independent of the incident energy. The energy resolution of the calorimeter can be expressed in terms of the distribution around the correlation line, which we found to be very good at about $ 19\% / \sqrt{E(\rm{GeV})}$ for pions.
