Neutron activation and prompt gamma intensity in Ar/CO${}_2$-filled neutron detectors at the European Spallation Source

E. Dian, K. Kanaki, R. J. Hall-Wilton +2

Monte Carlo simulations using MCNP6.1 were performed to study the effect of neutron activation in Ar/CO${}_2$ neutron detector counting gas. A general MCNP model was built and vali…
