摘要
A new type of particle identification (PID) detector based on measurements of 1-D Time-Of-Propagation (TOP) and 1-D space information is described. Geant4 toolkit is used to simulate the propagation of Cherenkov photon in thin quartz bar radiator. Contributions to the timing uncertainty are discussed. The pi/K separability (S (0)) is defined and its dependence on the particle momentum, incident angle and propagation length are studied, respectively.
