Appropriate fuelling and seeding strategies in each geometry have combined good confinement with density around the Greenwald level, accompanied by ELMS shown to have explicitly Type I character. For lower triangularity, argon injection leads to a reduction in normalized ELM energy losses averaged over several fluctuations, relative to unseeded scaling at comparable frequency and confinement but lower density. This generalizes a similar result in earlier studies [14, 15]. Optimized seeding tends always to decrease ELM frequencies too, so that the average energy efflux in ELMs is significantly diminished, down to only approximate to10% of input power in the lowest example included. At least for lower triangularity again, electron pedestal temperature is cooled by argon, which tends also to lower peak pedestal pressure before each consequently smaller fluctuation. However, the pedestal density is raised, and at higher radiation fractions this can restore unseeded peak pedestal pressure and roughly ELM size, but still at lower frequency. The underlying physics of Type I instabilities defined by pedestal collisionality appears to prevail in all cases both with and without seeding. High performance H-modes with both reduced core transport and moderated steady and transient power loads through added impurities therefore seem to come closer to a fully integrated scenario for Q = 10 operation in ITER. 000031306 536__ $$0G:(DE-Juel1)FUEK250$$2G:(DE-HGF)$$aKernfusion und Plasmaforschung$$cE05$$x0 000031306 588__ $$aDataset connected to Web of Science 000031306 650_7 $$2WoSType$$aJ 000031306 7001_ $$0P:(DE-HGF)0$$aBudny, I.
