Radioluminescent characteristics of the EJ 299-33 plastic scintillator

Abstract The response of the EJ 299-33 plastic scintillator to energetic charged nuclear particles ranging from isotopes of hydrogen to isotopes of carbon has been determined over a wide energy range using a complex experimental setup and nuclear reactions induced by a 20 AMeV carbon beam on an aluminum target. A strong pulse-shape dependence of the generated light bursts on the impinging particle specie is observed, which makes this scintillator suitable, among other things, for neutron vs. γ - ray identification. Fit formulas are proposed for the normalized light output as a function of particle energy for eleven isotopes of elements ranging from hydrogen to carbon.
