Organic scintillator efficiency using a Monte Carlo code

Abstract

The TAYRA code was developed to calculate the efficiency of organic scintillators for neutrons in the energy range 0.08–15 MeV. The algorithm uses the Monte Carlo method and considers, for the simulation, elastic scattering on hydrogen and carbon, inelastic scattering on carbon, and the reactions ${}^{12}\text{C}\text{(rmn, n′)}\text{C}{}^{\mathrm{\ast }}\text{→ 3α}\text{and}{}^{12}\text{C(n, α)}{}^9\text{Be}$. The code is written in FORTRAN IV. The results obtained using TAYRA are compared with experimental and calculated efficiency data.
