TL;DR: In this paper, an electromagnetic theory is developed for a discharge having two plates of radius R and separation 2l, which accounts for the propagation of surface and evanescent waves from the discharge edge into the center and the role of capacitive and inductive fields in driving the power absorption.

TL;DR: In this paper, the authors investigated CF and CF2 radical production and loss mechanisms in capacitively-coupled 13.56 MHz CF4 and C2F6 plasmas.

TL;DR: In this paper, a novel electrostatic probe method is described in which the ion flux is determined from the discharging of an RF-biased capacitance in series with the probe by using a large-area planar probe, with a guard ring and located in or on other surfaces.

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, the authors studied the kinetics of O and F atoms in O2-based plasmas and showed that the widely used (steadystate) actinometry technique using 844nm emission from O 3p3P atoms is an unreliable measure of groundstate [O] variations.
