Short Description

Run the TORAY ray,-tracing code for ECH waves

Keywords

ray-tracing, paraxial, ECH

Long Description

The TORAY code is an adaptation to tokamak geometry of earlier work done for mirror geometry. TORAY uses the cold plasma dispersion relation for the ray tracing and various models may be chosen for the absorption. For ECCD, TORAY may use the adjoint approach specialized to ECCD by Cohen. The Cohen approach has been reworked by Lin-Liu to generalize the square magnetic well used in Cohen’s approach. In a third version of the ECCD calculation, Lin-Liu has added the effect of the wave polarization calculated from an externally evaluated dispersion relation rather than the approximation that the wave is right-hand circularly polarized, a condition that is not even approximately true for the ordinary mode as in the ITER design.

Typical workflows

This module is used to:

Setup profiles from ODS, OMFITprofiles, ZIPFITs, PRO_create, kineticEFITtime

Setup gyrotrons for a given shot and time.

Edit gyrotrons aiming if desired.

Run TORAY:

As stand-alone For entire shot Find critical density of entire shot Scan Density Scan Angle
