摘要: Abstract Dilute scintillation mixtures emit isotropic light for both fast and slow particles, but retain the Cherenkov cone from particles. Large volume detectors using photomultipliers to reconstruct relativistic tracks will also be sensitive particles if they are filled with these mixtures. Our data show that 0.03 g/l of b-PBD in mineral oil has a 2.4:1 ratio (in first 12 ns) positron tracks. The attenuation length is greater than 15 m wavelength above 400 nm, decay time about 2 ns component. There component larger (relative component) protons electrons. This effect allows particle identification by technique similar pulse shape discrimination. These features utilized LSND, neutrino detector at LAMPF.
