Pair_Production

Structure used to define parameters for production of multigroup pair production cross-sections.

Mandatory field(s)

• N/A

Optional field(s) - with default values

• interaction_types::Dict{Tuple{DataType,DataType},Vector{String}} = Dict((Photon,Photon) => ["A"],(Photon,Electron) => ["P"],(Photon,Positron) => ["P"]) : Dictionary of the interaction processes types, of the form (incident particle,outgoing particle) => associated list of interaction type, which values correspond:
  • (Photon,Photon) => ["A"] : absorption of incoming photon.
  • (Photon,Electron) => ["P"] : produced electron.
  • (Photon,Positron) => ["P"] : produced positron.
• angular_scattering_type::String=modified_dipole : type of angular scattering, which can takes the following values:
  • angular_scattering_type = modified_dipole : modified dipôle distribution, based on Poskus (2019) shape functions.
  • angular_scattering_type = sommerfield : Sommerfield distribution.

set_interaction_types(this::Pair_Production,interaction_types::Dict{Tuple{DataType,DataType},Vector{String}})

To define the interaction types for pair production processes.

Input Argument(s)

• this::Pair_Production : pair production structure.
• interaction_types::Dict{Tuple{DataType,DataType},Vector{String}} : Dictionary of the interaction processes types, of the form (incident particle,outgoing particle) => associated list of interaction type, which can be:
  • (Photon,Photon) => ["A"] : absorption of incoming photon.
  • (Photon,Electron) => ["P"] : produced electron.
  • (Photon,Positron) => ["P"] : produced positron.

Output Argument(s)

N/A

Examples

julia> pair_production = Pair_Production()
julia> pair_production.set_interaction_types( Dict((Electron,Electron) => ["S"]) ) # Only electron scattering, with photon absorption.

set_angular_scattering_type(this::Pair_Production,angular_scattering_type::String)

To define the pair_production photons angular distribution.

Input Argument(s)

• this::Pair_Production : pair_production structure.
• angular_scattering_type::String : angular scattering type.

Output Argument(s)

N/A

Examples

julia> pair_production = Pair_Production()
