Deconvolution of H-α profiles measured by Thomson scattering collecting optics

Research output: Contribution to journalArticlepeer-review

Abstract

A method using a multipoint Thomson scattering system to obtain spatially resolved local emissivity is described. The method involves Fourier decomposition with auxiliary constraints. Optimum solution is determined from an analysis of the entropy and the error of the inversion. The technique is applied to H-α emission profiles from the PDX tokamak.
