In this paper we investigated Cherenkov radiation component influence on the time of charged particle detection in LYSO(Ce) crystals. Description of the experiment setup and Monte Carlo simulation scheme are given. The scintillation and Cherenkov radiation processes in LYSO(Ce) crystal were simulated and studied experimentally with electron beam at Budker Institute of Nuclear Physics beam test facilities. The results of the measurements and simulation are presented. The effect of particle detection time shift due to Cherenkov radiation was obtained. It amounts of several tens of picoseconds for LYSO(Ce) crystal bar (it has dimensions of 3 × 4 × 50 mm 3 ). Beam test results are in good agreement with calculations.

LYSO（Ce）晶体中Cherenkov辐射分量的实验研究

在本文中，我们研究了Cherenkov辐射分量对LYSO（Ce）晶体中带电粒子检测时间的影响。给出了实验设置和蒙特卡洛模拟方案的描述。在Budker核物理研究所的电子束测试设备中，用电子束对LYSO（Ce）晶体中的闪烁和Cherenkov辐射过程进行了模拟和实验研究。给出了测量和仿真的结果。获得了由于切伦科夫辐射引起的粒子检测时间偏移的影响。LYSO（Ce）晶棒的尺寸为几十皮秒（尺寸为3×4×50 mm 3）。光束测试结果与计算结果非常吻合。
