Abstract:A new method for estimating the global erosion of beryllium (Be) in ITER is proposed. The method uses raytracing-aided tomography to reconstruct the three-dimensional (3D) profile of beryllium visible-light emissivity in boundary plasma from images captured with filtered cameras of VIS/IR wide angle viewing system, H-alpha (and Visible) Spectroscopy diagnostics and signals collected with Divertor Impurity Monitor. The light reflected into the detectors from metallic plasma-facing components (PFCs) is filtered … Show more
