The PANDA experiment at the international accelerator Facility for Antiproton and Ion Research in Europe (FAIR) near GSI, Darmstadt, Germany will address fundamental questions of hadron physics. Excellent particle identification is required to achieve the PANDA physics goals. Hadronic particle identification (PID) in the barrel region of PANDA target spectrometer will be delivered by a fast focusing DIRC (Detection of Internally Reflecfted Cherenkov light) counter. The Barrel DIRC will cover the polar angle range of 22 o –140 o and is designed to provide π/K separation for momenta up to 3.5 GeV/ c with a separation power of at least 3 standard deviations. Several reconstruction algorithms have been developed to determine the performance of the detector. The "geometrical reconstruction" determines the Cherenkov angle by relying primarily on the position of the detected photons. The "time imaging", however, utilizes both po...

PANDA桶式DIRC的颗粒识别算法

在德国达姆施塔特GSI附近的国际反质子和离子研究欧洲加速器设施（FAIR）上进行的PANDA实验将解决强子物理的基本问题。要实现PANDA物理目标，需要出色的颗粒识别能力。PANDA目标光谱仪桶形区域中的强子粒子识别（PID）将通过快速聚焦的DIRC（内部反射的契伦科夫光检测）计数器进行。枪管DIRC的极角范围为22 o –140 o，其设计目的是为力矩达到3.5 GeV / c的π/ K分离提供至少3个标准偏差的分离力。已经开发了几种重建算法来确定检测器的性能。“几何重建” 主要依靠检测到的光子的位置确定切伦科夫角。但是，“时间成像”同时利用了...
