Description

The influence of the RF heating on the Ni-impurity transport is studied from comparative analysis of two discharges in JET: the reference discharge no. 69808 without RF power and discharge no. 68383 with the maximum ICRF power of 8.3 MW which is applied to electrons in Hydrogen Minority Heating scheme. With this goal we use multi-fluid Weiland model with trace impurity approximation and input profiles of density and temperature from the two shots. For the most instable determined eigen modes are calculated diffusivity, convective velocity and peaking factor for the two shots, respectively.
