Performance of the LiF-TEA ring imaging Cherenkov detector at CLEO
We describe the particle identification capability of the CLEO RICH system. This system consists of a 1 cm thick LiF radiator coupled to a photon detector that uses wire proportional chambers filled with a mixture of CH4 and TEA. We discuss the yield of photoelectrons observed per ring and the angular resolution. We show the efficiencies achieved for particle identification and the associated fake rates from data collected with both CLEO III and CLEO-c detectors. Finally we show examples of the particle separation ability which is excellent for both CLEO III and CLEO-c data.
Review of Cherenkov Imaging Devices in Particle and Nuclear Physics Experiments
This review summarizes the properties and performance of the detectors of focused Cherenkov radiation that are used in several current and future particle and nuclear physics experiments. The order of presentation is guided by the physics motivation, which in turn informs the choice of technology.
A historical survey of ring imaging Cherenkov counters
Abstract In this survey we discuss the development of Ring Imaging Cherenkov (RICH) counters for particle identification. Since 1977, it has been based on the use of gaseous photosensors in detectors with gaseous amplification (MWPC and MSAC) and sensitive to single UV photons. The detectors are classified into three groups, each developed over the last sixteen years, but based on different techniques and readout methods. The main developments, and the principal operating RICH detectors, are described and critically analyzed in order to compare their respective absolute performances. The newer detector designs and photosensors are also discussed. The aim of this historical survey is to give an overview of the technique, even if not completely exhaustive, in order to help in understanding RICH counters, their problems and their possibilities.
