Particle-identification (PID) capability plays an essential role in identification of π/K in the momentum range up to 4 GeV/c over a wide angular region. A new concept of a Cherenkov detector for PID by means of measuring the time-of-propagation (TOP) of Cherenkov photons is described. The use of TOP information with an appropriate focussing mirror makes the image-fusing effect be disregarded and compactification can be realized while maintaining the high enough PID ability. The characteristic features, practical configurations and simulation results on the TOP detectors are also discussed.
