Extension of gyrokinetics to transport time scales
In the last decade, gyrokinetic simulations have greatly improved our theoretical understanding of turbulent transport in fusion devices. Most gyrokinetic models in use are [sigma]f simulations in which the slowly varying radial profiles of density and temperature are assumed to be constant for …

Finite drift orbit effects in a tokamak pedestal
… retains short perpendicular wavelengths such as gyrokinetics. To be applicable in the pedestal, the formalism must also be capable of treating background scales as short as p, and conveniently accounting for the effects of finite ion drift orbits whose size scales with p,, as well. To this end, …

Theoretical study of ion toroidal rotation in the presence of lower hybrid current drive in a tokamak
… of toroidal angular momentum is evaluated using gyrokinetics corrected to the higher order in poloidal rhostar. The higher order corrections lead to momentum redistribution even in the absence of rotation, which is called intrinsic momentum transport. The intrinsic momentum transport due to …
