Thomson scattering synthetic diagnostic module for the Cherab framework.

ABSTRACT

This contribution presents a Thomson scattering module developed for the Raysect and Cherab framework. Detailed models of spectroscopic diagnostic systems can be created in the framework, which deliver synthetic data with high precision due to accurate physical treatment of ray propagation and radiation phenomena. The addition of the presented module will allow us to model Thomson scattering systems that can aid both data validation and design. Two examples of such application are given. The first example shows the application of the module on the COMPASS tokamak edge Thomson scattering diagnostic and experimental data. The second example shows the possibility to use the framework and the Thomson scattering module as a design support tool.
