Recent experiments on the DIII-D tokamak have focused on determining the effect of trapped particles on the electron cyclotron current drive (ECCD) efficiency. Localized power deposition and current drive were observed for both L-mode and ELMing H-mode plasmas. The ECCD efficiency was measured for both co and counter injection. Overall, the experimental ECCD efficiency was in good agreement with the CQL3D Fokker-Planck model over a wide range of injection angles and plasma parameters.
