Validation of Hermes-3 turbulence simulations against the TCV-X21 diverted L-mode reference case

Nuclear Fusion
Electrostatic flux-driven turbulence simulations with the Hermes-3 code are performed in TCV L-mode conditions in forward and reversed toroidal field configurations, and compared to the TCV-X21 reference dataset (Oliveira et al 2022 Nucl.

Flux rope, hyperbolic flux tube, and late EUV phases in a non-eruptive circular-ribbon flare [PDF]

, 2017
We present a detailed study of a confined circular flare dynamics associated with 3 UV late phases in order to understand more precisely which topological elements are present and how they constrain the dynamics of the flare.

MHD simulation on magnetic compression of field reversed configurations with NIMROD

Nuclear Fusion, 2023
Magnetic compression has long been proposed a promising method for plasma heating in a field reversed configuration (FRC). However, it remains a challenge to fully understand the physical mechanisms underlying the compression process, due to its highly ...

Structure of magnetic fields in non-convective stars

, 2009
(Abridged) We develop a theoretical framework to construct axisymmetric magnetic equilibria in stars, consisting of both poloidal and toroidal magnetic field components.

In search of X-point radiator regime features in NSTX and DIII-D discharges with the snowflake divertor

Nuclear Materials and Energy
Experimental data from NSTX and DIII-D discharges with the snowflake (SF) divertor configurations are analyzed toward the development of the X-point radiator (XPR) concept. The XPR divertor regime was recently realized in standard divertor configurations

Investigation of conventional and Super-X divertor configurations of MAST Upgrade using SOLPS

, 2014
One of the first studies of MAST Upgrade divertor configurations with SOLPS5.0 are presented. We focus on understanding main prospects associated with the novel geometry of the Super-X divertor (SXD).

Hybrid simulation study on ion heating by low-frequency wave excited in a field-reversed configuration

Nuclear Fusion
In this paper, we use hybrid simulation to elucidate the plasma heating mechanism due to waves excited in Field-Reversed Configuration (FRC) plasma. The plasma parameters are a separatrix radius of 0.16 m and a separatrix length of 1.16 m ( x -point ...

Characterisation of the L-mode Scrape Off Layer in MAST: decay lengths

, 2015
This work presents a detailed characterisation of the MAST Scrape Off Layer in L-mode. Scans in line averaged density, plasma current and toroidal magnetic field were performed.
