ON APPLICATION OF INVERSE RADON TRANSFORM FOR DIAGNOSTICS OF ASYMMETRIC PLASMATIC RADIATION SOURCES

摘要

The distribution of radiation intensity in plasma that cannot be considered as cylindrically symmetric is reconstructed from side-on radiation profiles by application of the inverse Radon transform. The side-on radiation profiles can be usually measured in a smaller number of projection planes than needed for obtaining sufficiently accurate results by usage of the relevant programme involved in the environment MATLAB. Therefore, a method is proposed for completing the set of measured side-on profiles with a number of other side-on profiles obtained from the measured data by an interpolation. Some illustrative examples are presented.
