Summary
R5900 MA PMTs have proven to be an extremly reliable and easy to use detector for Cherenkov photons.
Several new methods were developed for the design of the detector surface, analysis of data and alignment of the optical system.
The HERA-B RICH counter showed an excellent performance in very adverse conditions.
