达姆施塔特FAIR的P´ANDA实验的管状飞行时间（TOF）探测器计划是一个使用8000个小闪烁体瓦的闪烁体瓦hodoscope （SciTil）。它将为软件触发器提供快速事件定时，否则P - ANDA的无触发数据采集方案，多轨道事件拓扑中的相对定时以及低动量区域的额外粒子识别。我们的目标是实现σ≃100 ps的时间分辨率。我们已经使用硅光电倍增管（SiPM）耦合有机闪烁体进行了测量。结果令人鼓舞，因此我们有信心达到所需的系统时间分辨率。
The barrel time-of-flight (TOF) detector for the P̄ANDA experiment at FAIR in Darmstadt is planned as a scintillator tile hodoscope (SciTil) using 8000 small scintillator tiles. It will provide fast event timing for a software trigger in the otherwise trigger-less data acquisition scheme of P̄ANDA, relative timing in a multiple track event topology as well as additional particle identification in the low momentum region. The goal is to achieve a time resolution of σ ≃ 100 ps. We have conducted measurements using organic scintillators coupled to Silicon Photomultipliers (SiPM). The results are encouraging such that we are confident to reach the required system time resolution.
