Sub-microsecond temporal evolution of edge density during edge localized modes in KSTAR tokamak plasmas inferred from ion cyclotron emission
B. Chapman, R. O. Dendy, K. G. McClements +4
Ion cyclotron emission (ICE) is detected during edge localised modes (ELMs) in the KSTAR tokamak at harmonics of the proton cyclotron frequency in the outer plasma edge. The emissi…
Stimulated emission of fast Alfvén waves within magnetically confined fusion plasmas
J W S Cook, R O Dendy, S C Chapman
A fast Alfvén wave with finite amplitude is shown to grow by a stimulated emission process that we propose for exploitation in toroidal magnetically confined fusion plasmas. Stimul…
Electron kinetics inferred from observations of microwave bursts during edge localised modes in the Mega-Amp Spherical Tokamak
S. J. Freethy, K. G. McClements, S. C. Chapman +5
Recent measurements of microwave and X-ray emission during edge localised mode (ELM) activity in tokamak plasmas provide a fresh perspective on ELM physics. It is evident that elec…
Proton Kinetic Effects in Vlasov and Solar Wind Turbulence
S. Servidio, K. T. Osman, F. Valentini +5
Kinetic plasma processes have been investigated in the framework of solar wind turbulence, employing Hybrid Vlasov-Maxwell (HVM) simulations. The dependency of proton temperature a…
Self-consistent kinetic simulations of lower hybrid drift instability resulting in electron current driven by fusion products in tokamak plasmas
J W S Cook, S C Chapman, R O Dendy
We present particle-in-cell (PIC) simulations of minority energetic protons in deuterium plasmas, which demonstrate a collective instability responsible for emission near the lower…
Increasing Lifetime of Recurrent Sunspot Groups within the Greenwich Photoheliographic Results
R. Henwood, S. C. Chapman, D. M. Willis
Long-lived (>20 days) sunspot groups extracted from the Greenwich Photo- heliographic Results (GPR) are examined for evidence of decadal change. The problem of identifying sunspot…
