Experimental observations and modelling of intrinsic rotation reversals in tokamaks
Y. Camenen, C. Angioni, A. Bortolon +8
The progress made in understanding spontaneous toroidal rotation reversals in tokamaks is reviewed and current ideas to solve this ten-year-old puzzle are explored. The paper inclu…
On the radial propagation of turbulence in gyro-kinetic toroidal systems
P. Migliano, R. Buchholz, S. R. Grosshauser +2
In this paper a conservation equation is derived for the radially dependent entropy in toroidal geometry using the local approximation of the gyro-kinetic framework. This equation…
Nonlinear seed island generation by three-dimensional electromagnetic, gyrokinetic turbulence
William Hornsby, Pierluigi Migliano, Rico Buchholz +4
Turbulence is shown to be critical to the onset and evolution of the neoclassical tearing mode, affecting both its growth and rotation. The interaction is here studied for the firs…
Analysis of Lithium Driven Electron Density Peaking in FTU Liquid Lithium Limiter Experiments
G. Szepesi, M. Romanelli, F. Militello +7
The impact of lithium impurities on the microstability and turbulent transport characteristics in the core of a typical FTU Liquid Lithium Limiter (LLL)(Mazzitelli et al., Nucl. Fu…
Toroidal momentum transport in a tokamak caused by symmetry breaking parallel derivatives
Tobias Sung, Rico Buchholz, Francis Casson +5
A new mechanism for toroidal momentum transport in a tokamak is investigated using the gyro-kinetic model. First, an analytic model is developed through the use of the ballooning t…
Ion temperature gradient instability at sub-Larmor radius scales with non-zero ballooning angle
Pierluigi Migliano, Yann Camenen, Francis Casson +2
Linear gyro-kinetic stability calculations predict unstable toroidal Ion Temperature Gradient modes with normalised poloidal wave vectors well above one () for standard…
