摘要
A dual -radiator Ring Imaging Cherenkov (dRICH) will provide charged hadrons particle identification in the hadronic end -cap of a general-purpose experiment at the future Electron-Ion Collider (EIC). We developed a prototype to test the performance and validate the use of Silicon Photo-Multipliers (SiPM), the baseline photo-sensor candidate for the dRICH. They provide a cheap, highly efficient technology and they are not sensitive to the high magnetic field. The general features of the detector, a detailed view of the prototype and its different configurations, the test beam performed, and the preliminary results we obtained are presented.
