In elementary particle physics experiments, scintillating-tile and fiber calorimeters are used to measure the energies of daughter particles produced in collisions of high-energy particles. This device generates a light pulse whose size is proportional to the energy of the incident particle. In this research, we could successfully improve the energy resolution of the calorimeter by using the avalanche photodiodes (APDs) as photosensors for the calorimeter, instead of photomultiplier tubes generally used for calorimeters.

在基本粒子物理实验中，闪烁瓦片和纤维量热仪被用来测量高能粒子碰撞产生的子粒子的能量。该装置产生光脉冲，其大小与入射粒子的能量成正比。在本研究中，我们可以成功地使用雪崩光电二极管(APD)作为量热计的光传感器来代替通常用于量热计的光电倍增管，从而提高量热计的能量分辨率。
