论文摘要
杰斐逊实验室的Gluex实验旨在通过研究光夸克媒介和重子来进行非扰动QCD的定量测试。安装了内部反射的Cherenkov光（DIRC）的探测器，以增强Gluex实验的粒子识别（PID）能力，通过提供清洁$π$/K的分离，最高3.7 GEV/$ C $在向前区域中的动量（$θ<11^{\ circ} $），将允许较高的效果和更高的效果，并允许使用hybrid mesons deceanding efferitive and efferity deceans deceand and deceand efferity deceand and decesing and veseing and veresing and deceaning and veshing。新的PID系统由退役的Babar Dirc计数器的散热器构建，并基于Superb FDIRC概念结合新的紧凑光子相机。整个系统在2019/2020期间成功安装和委托使用Beam。评估了系统的初始PID性能，并将其与Geant4模拟中的PID性能进行了比较。
The GlueX experiment at Jefferson Laboratory aims to perform quantitative tests of non-perturbative QCD by studying the spectrum of light-quark mesons and baryons. A Detector of Internally Reflected Cherenkov light (DIRC) was installed to enhance the particle identification (PID) capability of the GlueX experiment by providing clean $π$/K separation up to 3.7 GeV/$c$ momentum in the forward region ($θ<11^{\circ}$), which will allow the study of hybrid mesons decaying into kaon final states with significantly higher efficiency and purity. The new PID system is constructed with radiators from the decommissioned BaBar DIRC counter, combined with new compact photon cameras based on the SuperB FDIRC concept. The full system was successfully installed and commissioned with beam during 2019/2020. The initial PID performance of the system was evaluated and compared to one from Geant4 simulation.
