abstract = {To facilitate the estimation of heat loads on plasma-facing
components in fusion devices in various different magnetic
geometries, a heat load proxy model was developed based on
anisotropic diffusion. In this work, this model is compared
to the so-called field-line diffusion approach. To
facilitate the evaluation of these models, a novel synthetic
camera-based approach for obtaining heat load distributions
from Monte Carlo samples was also developed and implemented.
With the assistance of this synthetic camera, heat load
predictions for the Wendelstein 7-X divertor were obtained
and compared with infrared camera observations. It was found
that the anisotropic diffusion-based model achieved a closer
match to infrared camera observations, while still being
suitable in computational effort for large magnetic
configuration database scans.},
