Overview of MAST results

Jonathan Graves, Wilfred Anthony Cooper, Mario Ludovico Podesta, Jan Horacek, Ben McMillan, Ricardo Pérez Suárez, Otto Asunta

The Mega Ampere Spherical Tokamak (MAST) programme is strongly focused on addressing key physics issues in preparation for operation of ITER as well as providing solutions for DEMO design choices. In this regard, MAST has provided key results in understand ...

Poloidal asymmetries in edge transport barriers

Christian Gabriel Theiler

Measurements of impurities in Alcator C-Mod indicate that in the pedestal region, significant poloidal asymmetries can exist in the impurity density, ion temperature, and main ion density. In light of the observation that ion temperature and electrostatic ...

Inboard and outboard radial electric field wells in the H- and I-mode pedestal of Alcator C-Mod and poloidal variations of impurity temperature

Christian Gabriel Theiler

We present inboard (HFS) and outboard (LFS) radial electric field (Er) and impurity temperature (Tz) measurements in the I-mode and H-mode pedestal of Alcator C-Mod. These measurements reveal strong Er wells at the HFS and the LFS midplane in both regimes ...

The new TORPEX in-vessel toroidal conductor for the generation of a poloidal magnetic field

Ambrogio Fasoli, Ivo Furno, Fabio Avino

TORoidal Plasma EXperiment (TORPEX) is a Simple Magnetized Torus featuring open helical magnetic field lines obtained from the superposition of a small vertical component on the main toroidal field. This work introduces the experimental setup developed to ...

Basic characterization of TORPEX electrostatic modes in closed field line configurations

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Fabio Avino, Sébastien Jolliet

Electrostatic coherent modes are studied in the TORPEX device [Fasoli et al., Plasma Phys. Controlled Fusion 52, 124020 (2010)], in closed flux surfaces. The accessibility to this magnetic geometry is provided by a current-carrying in-vessel toroidal condu ...

Large Wind Farms and the Scalar Flux over an Heterogeneously Rough Land Surface

Marc Parlange, Chad Higgins, Marc Calaf Bracons

The influence of surface heterogeneities extends vertically within the atmospheric surface layer to the so-called blending height, causing changes in the fluxes of momentum and scalars. Inside this region the turbulence structure cannot be treated as horiz ...

Experimental assessment of Owen's second hypothesis on surface shear stress induced by a fluid during sediment saltation

Michael Lehning, Benjamin Andreas Walter

A widely used, yet thus far unproven, fluid dynamical hypothesis originally presented by P. R. Owen 50years ago, states that the surface shear stress induced by a fluid on the ground during equilibrium sediment saltation is constant and independent of the ...

Theory framework for scrape-off layer turbulence in limited tokamaks

Paolo Ricci, Joaquim Loizu Cisquella, Sébastien Jolliet, Federico David Halpern, Fabio Riva, Annamaria Mosetto, Christoph Wersal

In the present work we address the physical mechanisms determining the SOL width of a simple inner-wall limited (IWL) configuration. This seemingly simple configuration has important implications for ITER start-up plasmas, and has triggered an important IT ...

Impact of RMP magnetic field simulation models on fast ion losses

Jonathan Graves, Wilfred Anthony Cooper, David Pfefferlé, Cyril Misev

Two opposing approaches to include resonant magnetic perturbations (RMPs) in fast ion simulations are compared, one where the vacuum field caused by the RMP current coils is added to the axisymmetric MHD equilibrium, the other where the MHD equilibrium inc ...
