Regularized solution of the solar Bremsstrahlung inverse problem: model dependence and implementation issues

Abstract

We address an important inverse problem in solar plasma physics by means of an ‘ad hoc’ implementation of the Tikhonov regularization method. Our approach is validated in the case of different modifications of the mathematical model of the problem based on physical motivations, and for data sets obtained with synthetic experiments. Finally, an application to a real observation recorded by the NASA mission ‘Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI)’ is considered.
