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. | |||
