摘要：
Bolometry provides absolute measurements of total radiation losses of a plasma discharge and it is an essential instrument for the studies related to the understanding of the plasma behavior at different radiative fractions. In this paper we present the first results related to the implementation of a new reconstruction method for bolometry. The method is based on the maximum likelihood statistical principle. It allows the implementation of a methodology for the evaluation of the uncertainties accompanying the reconstruction and the calculated radiated power. The method has been tested using numerically simulated distributions and also on relevant experimental JET data.
