用Geant4蒙特卡罗程序确定LYSO闪烁晶体的位置分辨力

Determination of Position Resolution for LYSO Scintillation Crystals using Geant4 Monte Carlo Code

M. F. O. Yahya, F. Kocak

摘要:

LYSO闪烁晶体,由于其显着的特性,如高的光产额,快的衰减时间,小的莫里哀半径,和良好的辐射硬度,被提议用于土耳其加速器中心粒子工厂(TAC-PF)探测器的电磁量热计部分。本文采用重心法确定了电子在LYSO阵列中引发电磁簇射的碰撞坐标,量热模块包含9个晶体,每个晶体的横截面为25 mm,长度为200 mm,直径为$\times$。用能量在0.1 GeV-2 GeV范围内的电子研究了量热模块的响应。通过基于Geant 4的蒙特卡罗模拟,得到了该模块在晶体中心的二维位置分辨率为$σ_{R}(mm)=((3.95\pm0.08)/\sqrt{E})\oplus(1.91\pm0.11)$。

英文摘要:

LYSO scintillation crystals, due to their significant characteristics such as high light yield, fast decay time, small Moliére radius, and good radiation hardness, are proposed to be used for the electromagnetic calorimeter section of the Turkish Accelerator Center Particle Factory (TAC-PF) detector. In this work, the center of gravity technique was used to determine the impact coordinates of an electron initiating an electromagnetic shower in the LYSO array, the calorimeter module contains nine crystals, each 25 mm$\times$25 mm in cross-section and 200 mm in length. The response of the calorimeter module has been studied with electrons having energies in the range 0.1 GeV-2 GeV. By using the Monte Carlo simulation based on Geant4, the two-dimensional position resolution of the module is obtained as $σ_{R}(mm)=((3.95\pm0.08)/\sqrt{E})\oplus(1.91\pm0.11)$ at the center of the crystal.
