Possible influence of near SOL plasma on the H-mode power threshold
Nuclear Materials and Energy, 2017 A strong effect of divertor configuration on the threshold power for the L-H transition (PLH) was observed in recent JET experiments in the new ITER-like Wall (ILW) [1–3]. Following a series of EDGE2D-EIRENE code simulations with Be impurity and drifts a

FEATURES OF THE DEVELOPMENT OF A CIRCULAR SOLAR FLARE
Odessa Astronomical Publications, 2020 We present the results of the analysis of morphology and evolution of the circular solar flare using H-alpha images. H-alpha filtergrams were obtained with the Meudon spectroheliograph.

Fluctuation characteristics of the TCV snowflake divertor measured with high speed visible imaging [PDF]
, 2018 Tangentially viewing fast camera footage of the low-field side snowflake minus divertor in TCV is analysed across a four point scan in which the proximity of the two X-points is varied systematically.

Separatrices: the crux of reconnection [PDF]
, 2014 Reconnection is one of the key processes in astrophysical and laboratory plasmas: it is the opposite of a dynamo. Looking at energy, a dynamo transforms kinetic energy in magnetic energy while reconnection takes magnetic energy and returns is to its ...

Access to an ELM-suppressed X-point radiator regime in TCV snowflake minus configurations
Nuclear Materials and EnergyTCV’s operating regime with an X-point radiator (XPR) has been broadened by changing the magnetic geometry. XPRs have properties that could make them an attractive power exhaust solution for fusion reactors.

Viscous evolution of point vortex equilibria: The collinear state [PDF]
, 2011 When point vortex equilibria of the 2D Euler equations are used as initial conditions for the corre- sponding Navier-Stokes equations (viscous), typically an interesting dynamical process unfolds at short and intermediate time scales, before the long ...

Observation of lobes near the X-point in resonant magnetic perturbation experiments on MAST
, 2012 The application of non-axisymmetric resonant magnetic perturbations (RMPs) with a toroidal mode number n=6 in the MAST tokamak produces a significant reduction in plasma energy loss associated with type-I Edge Localized Modes (ELMs), the first such ...

Dynamics of vortex dipoles in anisotropic Bose-Einstein condensates
, 2015 We study the motion of a vortex dipole in a Bose-Einstein condensate confined to an anisotropic trap. We focus on a system of ordinary differential equations describing the vortices' motion, which is in turn a reduced model of the Gross-Pitaevskii ...
