Laser-Produced Light Sources

Laser-Produced Light Sources

Simulations in a relativistic, highly non-linear regime of Laser-plasma interaction make it possible to invesitgate light-sources, e.g. for X-rays. Those provide insight into ultrafast, time-resolved structural dynamics of materials, such as chemical reactions or phase transitions. We employ Particle-in-Cell simulations to reproduce the whole process from high energy electron generation to the emission of X-rays.

Simulation of Laser Particle Acceleration

Laser Particle Acceleration

High intensity lasers and their interaction with plasmas promise to enable table-top particle accelerators for a wide range of industrial and medical applications. We create detailed 3D and 2D simulations to study the particle evolution.

High Energy Density Physics

High Energy Density Physics

High Energy Density Physics spawns a wide range of topics. Among them is fast ignition fusion, an alternative approach to achieve ignition in laser nuclear fusion processes. It has the potential to relax density and temperature requirements and reduces the energy input. We propose a magnetically assisted (MA) fast ignition scheme.

Plasma-Surface Interaction

Plasma-Surface Interactions

Magnetic plasma confinement can never be ideal, and is inherently compromised by the necessity to rid the burning plasma of ash products and replace the hydrogen fuel. Moreover, in most devices the plasma core is connected to the vessel walls by a magnetically non-confined outer region, leading to a powerful exchange of matter between the plasma and the solid container. The sheer complexity of this edge physics demands multi-scale, multi-physics modelling.
Together with IEK-4, we are developing models combining Monte Carlo particle transport and plasma chemistry with a self-consistent description of electrostatic fields and gyromotion in the presence of geometrically complex boundaries.
