A positive-definite form of bounce-averaged quasilinear velocity diffusion for the parallel inhomogeneity in a tokamak
Jungpyo Lee, David Smithe, John Wright +1
In this paper, the analytical form of the quasilinear diffusion coefficients is modified from the Kennel-Engelmann diffusion coefficients to guarantee the positive definiteness of…
Quasilinear diffusion coefficients in a finite Larmor radius expansion for ion cyclotron heated plasmas
Jungpyo Lee, John Wright, Nicola Bertelli +4
In this paper, a reduced model of quasilinear diffusion by a small Larmor radius approximation is derived to couple the Maxwell's equations and the Fokker-Planck equation self-cons…
An analytic scaling relation for the maximum tokamak elongation against n=0 MHD resistive wall modes
Jungpyo Lee, Jeffrey P. Freidberg, Antoine J. Cerfon +1
A highly elongated plasma is desirable in order to increase plasma pressure and energy confinement to maximize fusion power output. However, there is a limit to the maximum achieva…
