    Abstract

    Transport codes provide a classical way to infer the profile of transport coefficients in fusion plasmas with sources: assuming given functionals for the transport coefficient profiles, the free parameters are iteratively adjusted to best reproduce the measurements. This work discusses a technique for the case of modulated experiments with sources, the matrix approach (MA), which avoids any a priori constraint of the profiles, and computes them by simply inverting pointwise a 2D matrix.
