摘要：

Fast reconnection such as driven by electron inertia qualitatively changes the Kadomtsev picture of the sawtooth collapse in tokamak discharges. The collapse occurs in two steps, a fast Kadomtsev-type reconnection followed by a rapid reformation of a q0 < 1 configuration. The latter is driven by the strong flows generated during the Kadomtsev phase. The theory provides a natural explanation of the main experimental observations including the snake phenomena.
