ELM and inter-ELM tungsten erosion sources in high-power, JET ITER-like wall H-mode plasmas
Nuclear Materials and Energy, 2022 Simulations of JET ITER-like wall high-confinement mode plasmas, including type-I edge-localised modes (ELMs), using JINTRAC for the background plasmas and ERO2.0 for tungsten erosion and transport, predict virtually perfect screening of the primary W ...

Nuclear Materials and Energy, 2023 Experimentally, it has been observed in high-confinement (H-Mode) plasmas with Edge Localised Modes (ELMs) on JET that the pressure pedestal (pe,ped) is degraded by approximately a factor of two when there is a change in electron separatrix density, ne ...

Ergodicity of gyrofluid edge localized ideal ballooning modes [PDF]
Plasma Physics and Controlled Fusion, 2012 The magnetic field structure associated with edge localised ideal ballooning mode (ELM) bursts is analysed by nonlinear gyrofluid computation. The linear growth phase is characterised by the formation of small scale magnetic islands. Ergodic magnetic field regions develop near the end of the linear phase when the instability starts to perturb the ...

Entropy, 2023 We investigate the effects of different stochastic noises on the dynamics of the edge-localised modes (ELMs) in magnetically confined fusion plasmas by using a time-dependent PDF method, path-dependent information geometry (information rate, information ...

Impact of wall materials and seeding gases on the pedestal and on core plasma performance
Nuclear Materials and Energy, 2017 Plasmas in machines with all metal plasma facing components have a lower Zeff, less radiation cooling in the scrape-off layer and divertor regions and are prone to impurity accumulation in the core. Higher gas puff and the seeding of low-Z impurities are

Simulations of edge localised mode instabilities in MAST-U Super-X tokamak plasmas [PDF]
Nuclear Fusion, 2020 The high heat fluxes to the divertor during edge localised mode (ELM) instabilities have to be reduced for a sustainable future tokamak reactor. A solution to reduce the heat fluxes could be the Super-X divertor, which will be tested on MAST-U. ELM simulations for MAST-U Super-X tokamak plasmas have been obtained, using JOREK.

Towards understanding edge localised mode mitigation by resonant magnetic perturbations in MAST [PDF]
Physics of Plasmas, 2013 Type-I Edge Localised Modes (ELMs) have been mitigated in MAST through the application of n=3,4, and 6 resonant magnetic perturbations. For each toroidal mode number of the non-axisymmetric applied fields, the frequency of the ELMs has been increased significantly, and the peak heat flux on the divertor plates reduced commensurately.
