TL;DR: In this article, a study of the principal operation aspects of standard ICRF heating antennas in the ion cyclotron wall conditioning (ICWC) mode is presented, including the ability of the antenna to ignite the cleaning discharge safely and reliably in different gases including those most likely to be used in ITER, the antenna capacity to couple a large fraction of the RF generator power (>50%) to low density plasmas and the RF power absorption schemes aimed at improved RF plasma homogeneity and enhanced conditioning effect.

TL;DR: In this article, the impact of increased s/q at outer radii on core confinement in low-triangularity JET and ASDEX Upgrade (AUG) experiments was investigated by predictive heat and particle transport modelling using the integrated modelling code CRONOS coupled to the GLF23 turbulent transport model.

TL;DR: Performance analysis shows that the new LIDAR Thomson scattering diagnostic system will have an effective spatial resolution of up to 1 cm in the magnetic midplane via magnetic flux surface mapping.

TL;DR: In this paper, the authors describe the first development and implementation of a closed loop edge localized mode (ELM) frequency controller using gas injection as the actuator, which has been extensively used in recent experiments on JET and it has proved to work well at ELM frequencies in the 15-40 Hz range.

TL;DR: In this paper, the authors extrapolate the performance using transport modelling benchmarked on the experimental database and indicate that the foreseen power upgrade (similar to 45 MW) will allow the development of non-inductive scenarios where the bootstrap current is maximized together with the fusion yield and not, as in present-day experiments, at its expense.
