GlueX DIRC计划
The GlueX DIRC Program
摘要：
GSTX实验位于杰斐逊实验室（JLab）的实验大厅D，利用~9 GeV的线性偏振光子束，提供了在高能光生中寻找混合介子的独特能力。最近完成了GREX的初始低强度阶段，并于2020年开始了高强度阶段，其中包括升级的K介子识别系统，称为DIRC（内部反射切伦科夫光检测），利用退役的BaBar DIRC的组件。K介子末态的确定将大大增强GWAX物理计划，以帮助推断传统（和潜在的混合）介子的夸克味含量。在这些会议记录中，我们介绍了GRESSX DIRC的安装和初始调试数据的分析
英文摘要：
The GlueX experiment is located in experimental Hall D at Jefferson Lab (JLab) and provides a unique capability to search for hybrid mesons in high-energy photoproduction, utilizing a ~9 GeV linearly polarized photon beam. The initial, low-intensity phase of GlueX was recently completed and a high-intensity phase has begun in 2020 which includes an upgraded kaon identification system, known as the DIRC (Detection of Internally Reflected Cherenkov light), utilizing components from the decommissioned BaBar DIRC. The identification of kaon final states will significantly enhance the GlueX physics program, to aid in inferring the quark flavor content of conventional (and potentially hybrid) mesons. In these proceedings we describe the installation of the GlueX DIRC and the analysis of initial commissioning data
