Monte Carlo simulations of response functions for gas filled and scintillator detectors with MCNPX code
چکیده انگلیسی

Monte Carlo simulation of a detector response function presents a very challenging problem. The detector response functions have been calculated for different neutron and gamma detectors: 3He gas filled proportional counter, NE213 organic scintillator, BrillanCe 350 or LaCl3(Tl), and an ionization chamber with mixed gas composition. MCNPX code was used for simulations. The simulations were done with different neutron and gamma energies. The effects of neutron scattering, wall effects, recoil continua and contribution from charged particles have been included. The detector response function for the NE213 organic scintillator was obtained with consideration of light output curves of different products of neutron reactions with materials of the scintillator. The simulated data has been compared with experiments.

Research highlights
► Response functions have been calculated for gas-filled and scintillation detectors.
► Simulations have used Monte Carlo calculation for neutron and gamma radiation.
► Different effects have been taken into account in the simulation.
► The simulated response functions have been compared with experiments.
► The obtained results are in a good agreement within the experiment uncertainty.
