cherab.phix.tools.raytransfer.import_phix_rtc(parent, equilibrium=None, grid_size=0.002)Source#

This is a helper function to easily set up the RayTransfer Cylinder object on PHiX configuration.

This function returns a instance of RayTransferCylinder object, the mask property of which is defined to cut out the limiter. The spatial resolution of the grid is only in the radial and Z-axis directions.

Parameters:

  • parent (Node) – Raysect’s scene-graph parent node

  • equilibrium (EFITEquilibrium | None) – EFITEquilibrium object, by default the instance loaded by import_equilibrium function.

  • grid_size (float) – 1 voxel size \((dr=dz)\), by default 2.0e-3 [m]

Returns:

cherab’s Ray Transfer Cylinder object

Return type:

RayTransferCylinder

Examples

from raysect.optical import World
from cherab.phix.tools.raytransfer import import_phix_rtc
world = World()
rtc = import_phix_rtc(world)
rtc.bins
13326

The grid shape and steps is as follows:

rtc.material.grid_shape
(90, 1, 165)
rtc.material.grid_steps
(0.002, 360.0, 0.002)
