RAPID SAWTOOTH COLLAPSE IN JET
The rapid collapse of a tokamak sawtooth oscillation in JET has been observed for the first time in detail on a fast time scale. Tomographic reconstruction of data from two X-ray cameras and ECE temperature profile measurements show that during the sawtooth collapse the central hot region is rapidly displaced off axis and is then redistributed around a surface of constant minor radius. The early phase of the collapse is clearly m=1. The theoretical implications of the measurements are discussed.
