TL;DR: It is shown in the Joint European Torus that NTMs can be readily destabilized by long-period sawteeth, such as obtained by sawtooth stabilization from ion-cyclotron heating or current drive, which has important implications for burning plasma scenarios, as alpha particles strongly stabilize the saweeth.

TL;DR: In this article, the performance of the hybrid regime was validated in JET experiments up to βN = 2.8 at low toroidal field (1.7 T), with plasma triangularity and normalized Larmor radius (ρ*) corresponding to identical ASDEX Upgrade discharges.

TL;DR: In this paper, a new scenario to delay or prevent neoclassical tearing mode (NTM) onset is presented, where toroidally directed ICRF waves are used to stabilize the sawtooth inversion radius.

TL;DR: In this article, the E???B shear stabilization of anomalous transport in JET hybrid discharges is studied via self-consistent predictive modelling of electron and ion temperature, ion density and toroidal rotation velocity performed with the GLF23 model.

TL;DR: In this article, a linear dependence is found between excess neutron rate and tritium concentration when the DT fusion rate is low, and simple models for the calculation of the neutron yield from the proton-triton reaction in a fusion reactor environment were derived.
