Abstract
We will in this paper discuss a novel concept for a ring imaging Cherenkov detector. It measures the time of propagation of the Cherenkov photons in a quartz radiator. The photon detectors are micro-channel-plate photo-multipliers with GaAsP photo-cathodes. The performance has been estimated to give a separation better than 3.5σ3.5σ between K and ππ at 4GeV/c. This detector, together with a compact focusing system to correct the chromatic effect, will have an even better resolution. We will show that it can achieve more than 4.2σ4.2σ separation between K and ππ at 4GeV/c. This detector is well suited for experiments at the Super B factory.
