Comparison of fast tomographic methods for application on the Soft X-Ray Tomography System on Wendelstein 7-X stellarator

摘要

The Wendelstein 7-X stellaratorpresently under construction in Greifswaldis foreseen to operate on a steady state regime. Under such a scenarioa constant diagnosis of the plasma characteristics is strongly envisaged. AX-ray tomography diagnosti is a particularly useful tool since a poloidal cross-section of the plasma's X-ray emissivity can be reconstructed and the plasma's position as well as MHD activity can be inferred.
