环形成像切伦科夫计数器（TOP计数器）是贝儿Ⅱ实验中的一种粒子识别探测器。已在Spring-8 LEPS束线上用2GeV正电子进行了真实的尺寸样机的制作和测试。成功地进行了微通道板光电倍增管石英辐射器的生产和装配。束流测试数据在环形图像、探测光子数分布和时间信息方面与全蒙特-卡罗模拟结果吻合较好。(C)2014爱思唯尔有限公司版权所有。
Ring imaging Cherenkov counter, named TOP counter, utilizing precise photon detection timing has been developed as a particle identification detector for the Belle II experiment. The real size prototype has been produced and tested with 2 GeV positrons at Spring-8 LEPS beam line. The quartz radiator production and assembling with microchannel plate photomultipliers was successfully carried out. The beam test data shows good agreement with full Monte-Carlo simulation results in the ring image and the distribution of number of detected photons and timing information. (C) 2014 Elsevier B.V.
