TL;DR: The results are important because they identify what is probably a universal Kolmogorov-like regime for kinetic turbulence; and because any physical process that produces fluctuations of the gyrophase-independent part of the distribution function may, via the entropy cascade, result in turbulent heating at a rate that increases with the fluctuation amplitude, but is independent of the collision frequency.

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 this article, a conceptual framework for understanding kinetic plasma turbulence as a generalized form of energy cascade in phase space is presented, emphasizing that conversion of turbulent energy into thermodynamic heat is only achievable in the presence of some (however small) degree of collisionality.

TL;DR: The Wendelstein 7-X (W7-X) as mentioned in this paper is a state-of-the-art ECRH-based system for plasma start-up and operation using electron cyclotron resonance heating (ECRH).

TL;DR: In this paper, the fundamental scale separations present in plasma turbulence are codified as an asymptotic expansion in the ratio ϵ ǫ = ρ i/a of the gyroradius to the equilibrium scale length.
