The time of flight of the microwave pulses was strongly affected by the shallow density gradients over the magnetic islands. A detailed analysis showed the existence of secondary reflection lavers inside the magnetic island, which is an indication of a strong density peaking. This may be explained by assuming that the particle transport is reduced inside the magnetic island.}, year = {1997}, journal = {Nuclear Fusion}, volume = {37}, number = {11}, pages = {1641-1646}, month = {Nov}, isbn = {0029-5515}, language = {eng}, }
