Abstract
The performance of the ring imaging Cherenkov counter (RICH) for the HERA-B experiment has been evaluated. The measured values of the basic parameters such as the number of detected photons per ring and Cherenkov angle resolution are found to agree with a priori estimates. Also at higher track densities, the detector is capable of identifying individual rings. Particle identification has been achieved by determining the momentum from tracks in the vertex detector and main tracking system, hits in the electromagnetic calorimeter and track directions as measured by the RICH.
