The silicon photomultiplier is a new type of photo-sensor with high efficiency for detection of photons but also a large rate of noise signals - around 1MHz/mm2, that are equal to signals of a single photon. We have demonstrated for the first time that such a sensor can be used successfully as a photon detector in RICH counters.

The article describes measurements with the first prototype of aerogel RICH detector based on silicon photomultiplier module with arrays of 64 SiPMs and light concentrators. We showed that such a detector can successfully detect single Cherenkov photons. Efficiency and signal to noise ratio can be further improved by use of light concentrators.

Publication of the first beam test results of the time-of-flight measurement with a MCP-PMT sensor used for position sensitive detection of single Cherenkov photons in a RICH counter. We showed that a 35 ps timing resolution can be achieved by using only Cherenkov photons produced by charge particles in the sensor window.

Inside spectrometers with limited space, the proximity focusing RICH with aerogel radiator can be used for particle identifiction. In recent years we introduced a new type of such a detector with multi-layer aerogel radiator. The paper describes the method for optimization of refractive indices of individual layers to minimize the error of Cherenkov angle measurement.
