Managing the heat exhaust presents one of the main challenges in the design of a spherical
tokamak reactor. The development of a robust exhaust solution is intrinsically linked to the …

Negative triangularity (NT) tokamak configurations may be more susceptible to magneto-
hydrodynamic instability, posing challenges for recent reactor designs centered around their …

We have carried out a detailed analysis that compares steady state versus pulsed tokamak
reactors. The motivations are as follows. Steady state current drive has turned out to be more …

Many applications in magnetic confinement fusion require the efficient calculation of surface
integrals with singular integrands. The singularity subtraction approaches typically used to …

Several problems in magnetically confined fusion, such as the computation of exterior
vacuum fields or the decomposition of the total magnetic field into separate contributions …

In this and the accompanying paper, the problem of the maximally achievable elongation.
The results are obtained by means of a general formulation culminating in a variational …

Shaping a tokamak plasma to have a negative triangularity may allow operation in an edge-
localized mode-free L-mode regime and with a larger strike-point radius, ameliorating …

Equilibrium is essential in the design of the Chinese Fusion Engineering Test Reactor
(CFETR). It is based on the principle underlying various physical and engineering issues …

Abstract The axisymmetric (n= 0) resistive wall mode instability is numerically investigated
for the negative triangularity plasma shape, which has shown several benefits in terms of …

A new burn control scheme for tokamaks is described where the total fusion power is
controlled by adjusting the plasma volume fraction that is packed into power dense regions …
