Abstract

Sawtooth oscillations have been studied with a wide variety of diagnostics in JET in additionally heated discharges. Multichordal measurements, combined with tomographical reconstructions, have allowed a detailed experimental study of the sawtooth collapse with high time resolution. It is shown that the initial part of the collapse has m=1 topology.
