Recent experimental and simulation work has substantially advanced the understanding of
L-mode plasma edge turbulence and plasma flows and their mutual interaction across the L …

A fast edge turbulence suppression event has been simulated in the electrostatic version of
the gyrokinetic particle-in-cell code XGC1 in a realistic diverted tokamak edge geometry …

The efficient operation of a tokamak is limited by several constraints, such as the transition to
high confinement or the density limits occurring in both confinement regimes. These …

Transport barrier formation and its relation to sheared flows in fluids and plasmas are of
fundamental interest in various natural and laboratory observations and of critical …

ABSTRACT A major scientific success story of magnetic fusion research in the past several
decades has been the theoretical development and experimental testing of the process of …

Results from recent experiment and numerical simulation point towards a picture of the LH
transition in which edge shear flows interacting with edge turbulence create the conditions …

Understanding and predicting turbulence in the edge and scrape-off layer (SOL) is critical for
the optimization of magnetic confinement fusion devices. While there has been progress …

The low-to-high confinement mode transition (L–H transition) is one of the key elements in
achieving a self-sustained burning fusion reaction. Although there is no doubt that the mean …

The first continuum gyrokinetic calculations of electrostatic ion scale turbulence are
presented for the case of a diverted tokamak geometry. The simulation model solves the …

The L to H mode transition occurs at a critical power which depends on various parameters,
such as the magnetic field, the density, etc. Experimental evidence on various tokamaks …
