The Cherenkov detector is a key element of the particle identification system in the VES fixed target experiment at IHEP (Protvino). It consists of a 1.6 m R-22 gas radiator and a system of 28 mirrors with photomultiplier tubes (PMTs) as photon detectors. This paper is giving an overview of a description of the detector design, its model used in a simulation, particle identification algorithm, and discussing procedures of obtaining calibration constants. The particle identification performance is demonstrated with the Monte-Carlo and experimental data analyses.

VES实验中使用Cherenkov检测器进行颗粒识别

Cherenkov检测器是IHEP（Protvino）的VES固定目标实验中颗粒识别系统的关键要素。它由一个1.6 m的R-22气体辐射器和一个由28个反射镜组成的系统，这些反射镜带有作为光子探测器的光电倍增管（PMT）。本文概述了检测器的设计，模拟中使用的模型，颗粒识别算法以及讨论获取校准常数的过程。通过蒙特卡洛和实验数据分析证明了颗粒识别性能。
