Abstract
Groups of frequency chirping modes observed between sawtooth crashes in the Alcator C-Mod tokamak are interpreted as reversed shear Alfve´n eigenmodes near the q ¼ 1 surface. These modes indicate that a reversed shear q profile is generated during the relaxation phase of the sawtooth cycle. Two important parameters, qmin and its radial position, are deduced from comparisons of measured density fluctuations with calculations from the ideal MHD
