We report on a 3D simulation model of electron Bernstein wave (EBW) emission from spherical tokamaks. EBW emission for ELM-free H-modes in MAST suggests that the EFIT code does not adequately represent the magnetic field within the transport barier. Using the EBW signal we determine a modified magnetic field. Time evolution of ECE spectra in 15-40 GHz range were simulated for NSTX plasmas.

Popisujeme 3D model simulace emise elektronových Bernsteinových vln (EBW) ze sférických tokamaků. EBW emise z ELM-free H-modů na MASTu naznačuje, že EFIT nepopisuje dobře magnetické pole v transportní barieře.Z EBW signalu jsme určili modifikované magneticke. Simulovaly jsme časový vývoj ECE spektra v rozsahu 15-40GHz pro NSTX plazma.
