The physics of turbulence localised to the tokamak divertor volume
Fusion generated within magnetically confined plasmas offers a promising route to clean baseload energy but the intense heat and particle flux generated in the process presents a major challenge for future power plant devices.

Thermal-hydraulic modelling and analysis of ITER tungsten divertor monoblock
The divertor is a fundamental component of fusion power plants, being primarily responsible for power exhaust and impurity removal via guided plasma exhaust.

The edge plasma turbulence and transport dynamics, as well as the divertor power loads during the thermal-quench phase of tokamak disruptions, are numerically investigated with BOUT++’s flux-driven six-field electromagnetic turbulence model.

Feedback system for divertor impurity seeding based on real-time measurements of surface heat flux in the Alcator C-Mod tokamak [PDF]
Mitigation of the intense heat flux to the divertor is one of the outstanding problems in fusion energy. One technique that has shown promise is impurity seeding, i.e., the injection of low-Z gaseous impurities (typically N2 or Ne) to radiate and ...

Three-dimensional simulations of laser-plasma interactions at ultrahigh intensities [PDF]
Three-dimensional (3D) particle-in-cell (PIC) simulations are used to investigate the interaction of ultrahigh intensity lasers ($> 10^{20}$ W/cm$^{-2}$) with matter at overcritical densities.

On the radiative equilibrium of irradiated planetary atmospheres [PDF]
The evolution of stars and planets is mostly controlled by the properties of their atmosphere. This is particularly true in the case of exoplanets close to their stars, for which one has to account both for an (often intense) irradiation flux, and from ...
