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: In this article, neutral beam injection into reversed magnetic shear DIII-D and ASDEX upgrade plasmas produces a variety of Alfvenic activity including toroidicity-induced Alfven eigenmodes (RSAEs) and reversed shear Alfven (RSE) during discharge current ramp phase when incomplete current penetration results in a high central safety factor and increased drive due to multiple higher order resonances.

TL;DR: The newly installed electron cyclotron emission imaging diagnostic on ASDEX Upgrade provides measurements of the 2D electron temperature dynamics with high spatial and temporal resolution and the application of singular value decomposition as a powerful tool for analyzing and filtering 2D data is presented.

TL;DR: A new electron cyclotron emission imaging diagnostic has been commissioned on the DIII-D tokamak and first data demonstrate the acquisition of coherent electron temperature fluctuations as low as 0.1%.

TL;DR: In this paper, the authors describe the application of singular value decomposition (SVDC) as a powerful tool for analyzing and filtering 2D electron cyclotron emission data, showing both the advantage of having a two-dimensional (2D) measurement, as well as some of the limitations of EH emission measurements.
