dexter.LarCurrent()

Bases: MachineObject, Current

Analytical Large Aspect Ratio Current with $g=1$ and $I=0$.

Notes

No $\psi$ bounds checks are performed in evaluations.

Example 
>>> current = dex.LarCurrent()

dexter.NcCurrent(path: str, interp_type: Interpolation1dType)

Bases: MachineObject, Current

Numerical plasma current profile reconstructed from a netCDF file.

Related quantities are computed by interpolating over the data arrays.

Parameters:

  • path (str) –

    The path to the NetCDF file.

  • interp_type (Interpolation1dType) –

    The 1D interpolation type.

Attributes:

  • path (str) –

    The path to the netCDF file.

  • netcdf_version (NetCDFVersion) –

    The netCDF file's version (SemVer).

  • interp_type (Interpolation1dType) –

    The 1D interpolation type.

  • psit_array (Array1 | None) –

    The toroidal flux' values.

  • psip_array (Array1 | None) –

    The poloidal flux' values.

  • g_array (Array1) –

    The poloidal current's $g$ values.

  • i_array (Array1) –

    The poloidal current's $I$ values.

Example 
>>> current = dex.NcCurrent(path, "Cubic")
