First principles of modelling the stabilization of microturbulence by fast ions
George J. Wilkie, Aylwin Iantchenko, Ian G. Abel +2
The observation that fast ions stabilize ion-temperature-gradient-driven microturbulence has profound implications for future fusion reactors. It is also important in optimizing th…
Ion-scale turbulence in MAST: anomalous transport, subcritical transitions, and comparison to BES measurements
F. van Wyk, E. G. Highcock, A. R. Field +4
We investigate the effect of varying the ion temperature gradient (ITG) and toroidal equilibrium scale sheared flow on ion-scale turbulence in the outer core of MAST by means of lo…
Optimisation of confinement in a fusion reactor using a nonlinear turbulence model
E. G. Highcock, N. R. Mandell, M. Barnes +1
The confinement of heat in the core of a magnetic fusion reactor is optimised using a multidimensional optimisation algorithm. For the first time in such a study, the loss of heat…
Local dependence of ion temperature gradient on magnetic configuration, rotational shear and turbulent heat flux in MAST
Y. -c. Ghim, A. R. Field, A. A. Schekochihin +3
Experimental data from the Mega Amp Spherical Tokamak (MAST) is used to show that the inverse gradient scale length of the ion temperature R/LTi (normalized to the major radius R)…
