报道了欧洲核子研究中心用于HARP实验的大面积闪烁体飞行时间探测器的结构和性能。本征计数器时间分辨率达到了~ 160ps。通过使用专用宇宙射线运行、快速激光系统和光束粒子校准，探测器的时间校准和监测精度保持在100ps以上。该探测器于2001年和2002年在t9ps光束线上运行。获得了~ 200ps的飞行时间分辨率，提供了大于3σ的π/p判别，动量高达4.0GeV/c。
The construction and performance of a large area scintillator-based time-of-flight detector for the HARP experiment at CERN are reported. An intrinsic counter time resolution of ∼160ps was achieved. The precision on the time calibration and monitoring of the detector was maintained at better than 100ps by using dedicated cosmic rays runs, a fast laser-based system and calibrations with beam particles. The detector was operated on the T9 PS beamline during 2001 and 2002. A time-of-flight resolution of ∼200ps was obtained, providing π/p discrimination at more than 3σ up to 4.0GeV/c momentum.
