Detailed Description

template<typename generator_t, typename physics_list_t, typename hit_surface_selector_t>
struct ActsFatras::detail::Interactor< generator_t, physics_list_t, hit_surface_selector_t >

Fatras interactor plugin for the Acts propagator.

This plugin must be added to the action list of the propagator and is the equivalent to the MaterialInteractor for the reconstruction. This implements surface-based simulation of particle interactions with matter using a configurable physics lists. The physics lists is called for every surface with valid material.

Template Parameters

generator_t	is a random number generator
physics_list_t	is a simulation physics lists
hit_surface_selector_t	is a selector of sensitive hit surfaces
