The simplest way to reconstruct plasma emission using two-views tomography : Needed properties and limitations

摘要

Increase our knowledge in the distribution of the plasma emmissivity goes through development of theoretical mid experimental tools, which use inverse problem methods, especially tomography techniques. Indeed, the information contained in the local emission, which can be achieved by tomographic plasma diagnostic, allows to access to the spatial distribution of ion and electron temperature and density. For a decade, a range of tomographic methods, including pseudo-inversion methods, analytic method and algebraic or statistic iterative methods, have been applied to solve this inverse problem in plasma diagnostic.
