cherab.imas.plasma.load_core_plasma(*args, time: float = 0, occurrence: int = 0, equilibrium: EFITEquilibrium | None = None, b_field: Function2D | None = None, psi_interpolator: Callable[[float], float] | None = None, time_threshold: float = inf, parent: _NodeBase | None = None, **kwargs) → PlasmaSource

Load core profiles and Create a Plasma object.

Prefer density_thermal over density profile.

Parameters:
*args

Arguments passed to the DBEntry constructor.

time: float = 0

Time for the core plasma, by default 0.

occurrence: int = 0

Occurrence index of the core_profiles IDS, by default 0.

equilibrium: EFITEquilibrium | None = None

Alternative EFITEquilibrium used to map core profiles. By default None: the equilibrium is read from the same IMAS query as the core profiles. Ignored if the core plasma is not available.

b_field: Function2D | None = None

Alternative 2D interpolator of the magnetic field vector (Br, Bphi, Bz). By default None: the magnetic field is loaded from the equilibrium IDS.

psi_interpolator: Callable[[float], float] | None = None

Alternative psi_norm(rho_tor_norm) interpolator. Used only if psi is missing in the core grid. By default None. Obtained from the equilibrium IDS.

mask

Mask function used for blending: (1 - mask) * f_edge + mask * f_core. By default, uses EFITEquilibrium’s inside_lcfs.

time_threshold: float = inf

Maximum allowed difference between the requested time and the nearest available time, by default numpy.inf.

parent: _NodeBase | None = None

Parent node in the Raysect scene graph, by default None. Typically a World instance.

**kwargs

Keyword arguments passed to the DBEntry constructor.

Returns:

Plasma object with core profiles.

Return type:

Plasma

Raises:
