Sawtooth behaviour in highly elongated TCV plasmas

Antoine Pochelon, Olivier Sauter, Ivo Furno, Holger Reimerdes, Andrei Martynov

The effect of plasma elongation kappa on the sawtooth behaviour is studied in ohmically heated TCV plasmas up to values of kappa = 2.8. Above a certain value of kappa, which varies from 2.2 to 2.6 and depends on the current profile, the sawtooth oscillatio ...
