HEDLines showcases interesting and important high-energy-density research carried out within OxCHEDS and its partner research groups. Each HEDLine summarises the research undertaken in 500 words or fewer. Research areas covered include plasma accelerators, laboratory astrophysics, inertial confinement fusion, dynamic compression, and high-field physics.

Take a look at our research highlights below.

Current or count: why quantifying ionisation isn't as simple as it sounds

First-principles calculations suggest the ‘ionisation’ measured by x-ray Thomson scattering is not necessarily the same ‘ionisation’ that appears in simplistic atomic models.

Plasticity mechanisms and pole plots generated from molecular dynamics simulations of shocked tantalum and copper.21 June 2022

Slip-slip competition: plasticity causes rotation, except when it doesn't

A combined computational-experimental study shows how competition between rivalling slip systems in a dynamically compressed metal can suppress lattice rotation

Collision of two counterpropagating plasma jets.28 March 2022

The conduction reduction: why transporting heat around a galaxy cluster is harder than you think

An experiment at the National Ignition Facility demonstrates how the thermal conductivity of a turbulent magnetised plasma is reduced by two orders of magnitude below its classical value.

Links in another world: the influence of a shattered crystal on the world's most expensive thermometer

A computational study outlines the physical limits and requirements of a dynamic temperature diagnostic for dynamic-compression experiments.

Drive smarter, not harder: low convergence ratio ICF experiments may still yield substantial gains

A simulation campaign shows that nuclear fuel compressed to comparatively low densities in inertial confinement fusion experiments can generate useful amounts of energy.
