44. A hybrid (ablation-expansion) model for low-density foams

Lubomír Hudec (FNSPE, Czech Technical University in Prague, Czech Republic)

oral

Low-density foams have a wide variety of applications in the fields of inertial confinement fusion and high energy density physics. However, direct simulations of laser interaction with foam targets are difficult and computationally expensive due to the necessity to spatially resolve the density differences in the foam microstructure in order to capture the underlying physical phenomena....

28. Experimental studies of laser interactions with low density porous targets

Jiří Limpouch (Czech Technical University in Prague)

oral

Low density porous materials are considered in the inertial confinement fusion studies as a promising material for smoothing laser beam intensity modulations and creation of spherical targets filled with a liquid deuterium-tritium fuel. However, the role of intrinsic structural foam inhomogeneities on seeding instabilities is not known. Experimental studies and modelling of the time of foam...

11. Kinetic modelling of laser absorption in foams

Sviatoslav Shekhanov (ELI-Beamlines Center)

oral

Low density foams have interesting properties that make them attractive for fundamental studies of laser plasma interaction and for various applications such as inertial confinement fusion and bright sources of X-ray emission. However, the process of transformation of a cold foam into a hot plasma is complicated and not well-known. Experiments and numerical simulations show that the ionization...

63. On the evolution of the hot electron sheath

Dr Piotr Raczka (IPPLM)

oral

The laser-target interaction at high laser intensity results in the generation of a population of fast electrons which penetrate through and spread across the target, forming an electron sheath at the target surface. The quasi-static sheath electric field creates a potential barrier close to the target surface that repels hot electrons with energies below the barrier height. The hot electrons...

46. Smilei: an open-source PIC code for laser-plasma interaction

Frederic Perez (LULI, Ecole Polytechnique)

Invited

First released in 2015, the particle-in-cell code Smilei [1] has grown into a high-performance, user-friendly, multi-purpose tool for laser-plasma kinetic simulations. Production runs have started in 2018, and are now commonly carried out by tens of teams across the world.

In the past four years, significant improvements have been brought to the code. Additional physics has been introduced:...

8. Vortex-driven ultrahigh magnetic field generation in microtube implosion

Masakatsu Murakami

oral

Microtube implosion is a novel scheme to generate ultrahigh magnetic fields of megatesla-order. The implosion is driven by ultraintense and ultrashort laser pulses. It was necessary, however, to prepare a kilotesla-order seed magnetic field to ensure the Larmor motions of both electrons and ions and to finally generate ultrahigh magnetic fields. Recently we have found a new method under...
