创新的桶DIRC(探测内反射切伦科夫光)计数器将在德国达姆施塔特的新反质子和离子研究设施(FIRE)的熊猫实验的中心区域提供强子粒子识别(PID)。该探测器的设计是为了分离带电的介子和介子，动量高达3.5GeV/c，至少有3个标准偏差，覆盖了22̂−140̂的极角范围。用微通道板式光电倍增管阵列探测切伦科夫光子的位置和到达时间，位置分辨率为2 mm，时间精度约为100ps。时间成像重建是为了最大限度地利用观测数据和确定探测器性能而发展起来的。该重建算法通过使用基于检测到的每个像素中的光子传播时间的概率密度函数直接计算最大似然来执行粒子识别，该概率密度函数直接从数据或解析或从详细模拟确定。
The innovative Barrel DIRC (Detection of Internally Reflected Cherenkov light) counter will provide hadronic particle identification (PID) in the central region of the PANDA experiment at the new Facility for Antiproton and Ion Research (FAIR), Darmstadt, Germany. This detector is designed to separate charged pions and kaons with at least 3 standard deviations for momenta up to 3.5 GeV/c, covering the polar angle range of 22̂−140̂. An array of microchannel plate photomultiplier tubes is used to detect the location and arrival time of the Cherenkov photons with a position resolution of 2 mm and time precision of about 100 ps. The time imaging reconstruction has been developed to make optimum use of the observables and to determine the performance of the detector. This reconstruction algorithm performs particle identification by directly calculating the maximum likelihoods using probability density functions based on detected photon propagation time in each pixel, determined directly from the data, or analytically, or from detailed simulations.
