Novatron: Equilibrium and Stability
Kristoffer Lindvall, Rickard Holmberg, Katarina Bendtz +2
The Novatron is a fusion concept characterized by its axisymmetric mirror-cusp magnetic topology. The magnetic field exhibits good curvature and a high mirror ratio. Plasma equilib…
Axial Confinement in the Novatron Mirror Machine
J. Scheffel, J. Jäderberg, K. Bendtz +2
The Novatron magnetic mirror fusion reactor concept features significant advantages. These include stability against MHD interchange and kinetic DCLC modes, axisymmetry, and minimi…
Introducing the Novatron, a novel mirror fusion concept
Jan Jäderberg, Katarina Bendtz, Kristoffer Lindvall +5
A new magnetic mirror-cusp concept is described - the Novatron - with the potential to confine compact and stable fusion plasmas. Traditionally, the major challenges for open field…
A Time-Spectral Method for Initial-Value Problems Using a Novel Spatial Subdomain Scheme
Kristoffer Lindvall, Jan Scheffel
We analyse a new subdomain scheme for a time-spectral method for solving initial boundary value problems. Whilst spectral methods are commonplace for spatially dependent systems, f…
SIR - an Efficient Solver for Systems of Equations
Jan Scheffel, Kristoffer Lindvall
The Semi-Implicit Root solver (SIR) is an iterative method for globally convergent solution of systems of nonlinear equations. Since publication, SIR has proven robustness for a gr…
Optimizing time-spectral solution of initial-value problems
Jan Scheffel, Kristoffer Lindvall
Time-spectral solution of ordinary and partial differential equations is often regarded as an inefficient approach. The associated extension of the time domain, as compared to fini…
A Time-spectral Approach to Numerical Weather Prediction
Jan Scheffel, Kristoffer Lindvall, Hiu Fai Yik
Finite difference methods are traditionally used for modelling the time domain in numerical weather prediction (NWP). Time-spectral solution is an attractive alternative for reason…
