Abstract

This paper presents the photon physics models used in Serpent 2 Monte Carlo particle transport code. The four main photon interactions – photoelectric effect, Rayleigh scattering, Compton scattering and electron–positron pair production – are included in Serpent, accompanied by three secondary photon production mechanisms (electron–positron annihilation, atomic relaxation and bremsstrahlung emitted by electrons and positrons). Models, algorithms and data used for these interaction mechanisms are described, including new efficient sampling algorithms for photoelectron direction and electron–positron pair production.
