Elastic_Collision

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

Mandatory field(s)

• N/A

Optional field(s) - with default values

• interaction_types::Dict{Tuple{DataType,DataType},Vector{String}} = Dict((Electron,Electron) => ["S"],(Positron,Positron) => ["S"]) : Dictionary of the interaction processes types, of the form (incident particle,outgoing particle) => associated list of interaction type, which values correspond:
  • (Electron,Electron) => ["S"] : elastic interaction of electrons.
  • (Positron,Positron) => ["S"] : elastic interaction of positrons.

set_model(this::Elastic_Collision,model::String,is_KC::Bool=true)

To define the elastic scattering model.

Input Argument(s)

• this::Elastic_Collision : elastic collisions structure.
• model::String : model of elastic scattering:
  • rutherford : screened Rutherford cross-sections.
  • boschini : screened Mott cross-sections.
• is_KC::Bool : Apply Karakow correction (true) or not (false).
• is_SC::Bool : Apply Seltzer correction (true) or not (false).

Output Argument(s)

N/A

Examples

julia> elastic_collisions = Elastic_Collision()
julia> elastic_collisions.set_model("rutherford")

set_transport_correction(this::Elastic_Collision,is_ETC::Bool)

Enable or not extended transport correcton.

Input Argument(s)

• this::Elastic_Collision : elastic collisions structure.
• is_ETC::Bool : Enable (true) or not (false) extended transport correcton.

Output Argument(s)

N/A

Examples

julia> elastic_collisions = Elastic_Collision()
julia> elastic_collisions.is_ETC(false)

set_solver(this::Elastic_Collision,solver::String)

Dictate how the cross-sections is distributed to the Boltzmann and the Fokker-Planck operators.

Input Argument(s)

• this::Elastic_Collision : elastic collisions structure.
• solver::String : model of elastic scattering:
  • BTE : the cross-sections are made to be used with the Boltzmann operator.
  • FP : the cross-sections are made to be used with the Fokker-Planck operator.
  • BFP : the cross-sections are distributed to the Boltzmann and Fokker-Planck operator.

Output Argument(s)

N/A

Examples

julia> elastic_collisions = Elastic_Collision()
julia> elastic_collisions.is_AFP(false)

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

To define the interaction types for Elastic_Collision processes.

Input Argument(s)

• this::Elastic_Collision : elastic collisions 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:
  • (Electron,Electron) => ["S"] : elastic interaction of electrons.
  • (Positron,Positron) => ["S"] : elastic interaction of positrons.

Output Argument(s)

N/A

Examples

julia> elastic_collisions = Elastic_Collision()
julia> elastic_collisions.set_interaction_types( Dict((Positron,Positron) => ["S"]) ) # Elastic only for positrons
