Martian pedestal craters: Marginal sublimation pits implicate a climate‐related formation mechanism [PDF]

Geophysical Research Letters, 2008
Pedestal craters on Mars are defined by an outward-facing scarp forming a plateau perched tens of meters above the surrounding terrain. Their origin has been attributed to impact armoring of the surface and subsequent removal of inter-crater terrain by ...

Prediction of the kinetic profiles in H-mode plasma discharges on EAST using core-pedestal coupling [PDF]

Scientific Reports
The physical processes in tokamak plasma are strongly related to the coupling between the core and the pedestal. The accurate prediction of the kinetic profiles (electron temperature and density) from the pedestal to the core lays the physics basis for ...

Impact of the new TCV baffled divertor upgrade on pedestal structure and performance

Nuclear Materials and Energy, 2021
A new set of carbon tiles, neutral beam heating optics and gas baffles were installed on TCV during the baffled divertor upgrade in early 2019. The installation of the baffles allows a deconvolution of the roles of main chamber and divertor neutral ...

Effect of the isotope mass on pedestal structure, transport and stability in D, D/T and T plasmas at similar β N and gas rate in JET-ILW type I ELMy H-modes

Nuclear Fusion, 2023
The work describes the pedestal structure, transport and stability in an effective mass ( A _eff ) scan from pure deuterium to pure tritium plasmas using a type I ELMy H-mode dataset in which key parameters that affect the pedestal behaviour (normalized ...

Micro-tearing mode dominated electron heat transport in DIII-D H-mode pedestal

Nuclear Fusion, 2023
A new, comprehensive set of evidence reveals that Micro-Tearing Modes (MTMs) dominate pedestal electron heat transport in an H-mode experiment in the DIII-D tokamak. The experiment investigates the role of MTMs by scanning pedestal collisionality, a main

Direct measurement of the electron turbulence-broadening edge transport barrier to facilitate core–edge integration in tokamak fusion plasmas

Nuclear Fusion, 2023
The integration of a high-performance core and a dissipative divertor, or the so-called ‘core–edge integration,’ has been widely identified as a critical gap in the design of future fusion reactors.

Direct Gyrokinetic Comparison of Pedestal Transport in JET with Carbon and ITER-Like Walls [PDF]

, 2019
This paper compares the gyrokinetic instabilities and transport in two representative JET pedestals, one (pulse 78697) from the JET configuration with a carbon wall (C) and another (pulse 92432) from after the installation of JET's ITER-like Wall (ILW ...

Self-consistent pedestal prediction for JET-ILW in preparation of the DT campaign [PDF]

, 2019
The self-consistent core-pedestal prediction model of a combination of EPED1 type pedestal prediction and a simple stiff core transport model is able to predict Type I ELMy (edge localized mode) pedestals of a large JET-ILW (ITER-like wall) database at ...
