Radiative pulsed L-mode operation in ARC-class reactors
S. J. Frank, C. J. Perks, A. O. Nelson +8
A new ARC-class, highly-radiative, pulsed, L-mode, burning plasma scenario is developed and evaluated as a candidate for future tokamak reactors. Pulsed inductive operation allevia…
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…
Tokamak elongation: how much is too much? II Numerical results
Jungpyo Lee, Antoine Cerfon, Jeffrey P. Freidberg
The analytic theory presented in Paper I is converted into a form convenient for numerical analysis. A fast and accurate code has been written using this numerical formulation. The…
Tokamak elongation: how much is too much? I Theory
Jeff P. Freidberg, Antoin Cerfon, Jungpyo Lee
In this and the accompanying paper the problem of the maximally achievable elongation in a tokamak is investigated. The work represents an extension of many earlier studies, which…
Accurate Derivative Evaluation for any Grad-Shafranov Solver
L. F. Ricketson, A. J. Cerfon, M. Rachh +1
We present a numerical scheme that can be combined with any fixed boundary finite element based Poisson or Grad-Shafranov solver to compute the first and second partial derivatives…
A fast, high-order solver for the Grad-Shafranov equation
Andras Pataki, Antoine J. Cerfon, Jeffrey P. Freidberg +2
We present a new fast solver to calculate fixed-boundary plasma equilibria in toroidally axisymmetric geometries. By combining conformal mapping with Fourier and integral equation…
Analytic fluid theory of beam spiraling in high-intensity cyclotrons
Antoine J. Cerfon, Jeffrey P. Freidberg, Felix I. Parra +1
Using a two-dimensional fluid description, we investigate the nonlinear radial-longitudinal dynamics of intense beams in storage rings and cyclotrons. With a multiscale analysis se…
