Threshold Cerenkov Detector With Radial Segmentation permits correlation between number of photons produced in concentrically arranged radiator tubes and particle momentum that yields a 90% confidence level for e, μ, &pgr;, and p identification up to 4-5 GeV/c or four to five times greater than the momentum limit for particle identification in Threshold Cerenkov Detectors, wherein detector has three concentric cylinders with a total of 25 radiator tubes, each cylinder of tubes has different medium; and four scintillators are employed which trigger cosmic particles within a window of 5ns. Radiator designs produce more photons as particles enter improved TCDRS design and fewer photons as they leave. Correlation between the number of photons produced in the tubes and the particle momentum yields about a 90% confidence level for e, μ, &pgr;, and p identification up to 4-5 GeV/c times greater than the momentum limit for particle identification using existing Threshold Cerenkov Detectors.
