Theory for the Power Threshold of the $L\text{−}H$ Transition in Tokamaks
feeds.aps.org · By B. De Lucca, P. Ricci, B. Labit, D. Mancini, L. N. Stenger & Z. Tecchiolli ·
The Brief
- Flux-driven two-fluid simulations of a diverted tokamak show a confinement transition when a critical heating threshold is exceeded.
- The simulated transition is presented as resembling the experimentally observed L-H transition.
- The work provides a theoretical account of the power threshold for the L-H transition in tokamaks.
Why it matters
The power needed to trigger the L-H transition sets the heating requirements for tokamak fusion devices, so a theory for this threshold helps plan future reactors and experiments.
