在不同闪烁体尺寸、光导和光电倍增管（PM）的各种组合下，使用2-GeV/c束，检查了2 mm厚TOF计数器的性能。对于50 mm W × 150 mm L的直接耦合2 in计数器，获得的时间分辨率（σ）为90 ps。150 mmw× 250 mml计数器通过扭曲光波导耦合到PMs，140 ps。对厚度为40 mm的150 mm × 12000 mm计数管进行了测试，获得了60 ps的脉冲宽度。
The performance of 2 mm-thick TOF counters was examined under various combinations of different scintillator sizes, light-guides, and photo-multipliers (PMs) with the use of a 2-GeV/c beam. The obtained time resolution (σ) was 90 ps for a 50 mmw× 150 mmlcounter with directly coupled 2 in. diameter PMs, and 140 ps for a 150 mmw× 250 mmlcounter coupled through twisted light-guides to the PMs. A 40 mm-thick 150 mmw× 12 000 mmlcounter was also tested, and 60 ps was obtained.
