On JET and ASDEX Upgrade, it has been observed that the electron temperature and electron density profiles can have different relative pedestal positions (so-called relative shift). As shown in [4,5], the increase of the relative shift is correlated with the reduction in the normalized pressure gradient, leading to a weakening of the pedestal stability. Therefore, in this work, analysis of the effect of the relative shift has been carried on the COMPASS tokamak discharges. The dataset used for analysis was obtained during two dedicated experimental campaigns in 2015 and 2016 [6]. Systematic measurements of pedestal structure were performed in Ohmic and NBIassisted Type I ELMy H-modes [7]. For PNBI exceeding 200 kW the electron pedestal temperature reached 300 eV, allowing to achieve pedestal collisionality Vped* < 1 at q95 ~3. Measurements during the last 30% of the ELM cycle were considered for analysis. Pracoviště Ústav fyziky plazmatu Kontakt Vladimíra Kebza, kebza@ipp.cas.cz, Tel.: 266 052 975 Rok sběru 2018
