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 resolu tion are found to agree with a priori estimates. Also at higher track densi ties, the detector is capable of identifying individual rings. Particle ide ntification has been achieved by determining the momentum from tracks in th e vertex detector and main tracking system, hits in the electromagnetic cal orimeter and track directions as measured by the RICH.
