论文摘要
在本文中，我们调查了能量分辨率从更改角度和发射率光子位置的效果，以5 $ \ times $ 5 $ 5的水晶矩阵（25 $ \ times $ 25 $ \ times $ \ times $ 200 $ 200）mm $ $^{3} $ lyso lyso scintilling晶体。这些晶体已被提出用于土耳其加速器中心粒子工厂（TAC-PF）检测器的电磁热量表。能量分辨率作为$σ_{e}/e = 0.42 \％/\ sqrt {e/gev} \ oplus 1.60 \％$在矩阵中心的50 MEV至2 GEV的矩阵中心。当我们检查能量分辨率对光子入射角的依赖性时，分辨率开始以大于$ 2^{\ circ} $在5 $ \ times $ 5 $ 5晶体矩阵上的角度恶化。此外，中央晶体角处的能量分辨率比中央晶体中心的中心差，在50 MeV时为1.3，在2 GEV时为1.1。
In this paper, we investigate the effect on energy resolution from changing the angle and the position of incidence photon for a 5 $\times$ 5 crystal matrix built with (25 $\times$ 25 $\times$ 200) mm$^{3}$ LYSO scintillating crystals. Those crystals have been proposed for the electromagnetic calorimeter of the Turkish Accelerator Center-Particle Factory (TAC-PF) detector. The energy resolution was obtained as $σ_{E}/E = 0.42 \% / \sqrt{E/GeV} \oplus 1.60 \%$ at the center of the matrix in the energy range of 50 MeV to 2 GeV. When we examined the dependence of the energy resolution on the incidence angle of the photon, resolution began to deteriorate at angles greater than $2^{\circ}$ on the 5 $\times$ 5 crystal matrix. Moreover, energy resolution at the corners of the central crystal was worse than at the center of the central crystal by a factor of 1.3 at 50 MeV and 1.1 at 2 GeV.
