A simplified charged particle transport model along open field lines.

Parameters:

• equilibrium (bluemira.equilibria.equilibrium.Equilibrium) – The equilibrium defining flux surfaces.

• first_wall (bluemira.geometry.coordinates.Coordinates) – the first wall to analyse

• dx_mp (float) – The midplane spatial resolution between flux surfaces [m]

• source_sol_dl (float | None) – source scrape off layer discretisation (approximate)

Returns:

• dx_omp – The midplane spatial resolution between flux surfaces at the outboard [m]

• dx_imp – The midplane spatial resolution between flux surfaces at the inboard [m]

• flux_surfaces – list of flux surfaces, all of which terminating at the first walls.

• x_sep_omp – intersection between the separatrix outboard and mid-plane.

• x_sep_imp – intersection between the separatrix inboard and mid-plane.

Return type:

tuple[numpy.typing.NDArray[float], numpy.typing.NDArray[float] | None, list[bluemira.equilibria.flux_surfaces.PartialOpenFluxSurface], float, float | None]
