In the present experiment the analysis of the radial profiles and time evolution of the plasma emissivity using the TJ-II bolometry
system <ref> M. A. Ochando ''et al.'' ''Up-down and in-out asymmetry monitoring based on broadband radiation detectors'' Fusion Sci. and Technol. '''50''' 313 (2006) </ref> after the inyection
of some selected impurities by gas puffing is proposed. The experiment aims at studying the above-mentioned link between the radially assymetric
emissivity and the measured and predicted <math>\Phi_1</math>. The measurement and evolution of <math>\Phi_1</math> will be tracked
during the discharges using the duplicated Langmuir probe system plasma floating potential measurements.
Numerical calculations of <math>\Phi_1</math> will be carried out with the neoclassical version of the code EUTERPE
at different radial locations.
The application of fluid tools is also foreseen for the comparison between simulations and with the experimental results.
