TL;DR: In this paper, the authors reviewed the 2014-2016 JET results in the light of their significance for optimising the ITER research plan for the active and non-active operation, stressing the importance of the magnetic configurations and the recent measurements of fine-scale structures in the edge radial electric.

TL;DR: The Wendelstein 7-X superconducting stellarator was used for the first high-performance plasma operation as discussed by the authors, achieving densities of up to 4.5 GHz with helium gas fueling.

TL;DR: In tokamak plasmas with a tearing mode, strong scattering of high power millimeter waves, as used for heating and noninductive current drive, is shown to occur.

TL;DR: The collective Thomson scattering (CTS) diagnostic proposed for ITER is designed to measure projected 1D fast-ion velocity distribution functions at several spatial locations simultaneously as discussed by the authors, where the frequency shift of scattered radiation and the scattering geometry place fast ions that caused the collective scattering in well defined regions in velocity space, here dubbed interrogation regions.

TL;DR: In this article, anomalous scattering of high power millimetre waves from gyrotrons at 140 and 110 GHz was investigated for plasma with rotating islands at TEXTOR, where the magnetic field and plasma density influence the spectral content of the scattered waves and their power levels significantly.
