Jointly with each scientific day, PLAS@PAR organizes a photo/video competition open to all PLAS@PAR researchers.


Photo & video competition 2017


1st Prize: Manuel de Anda Villa, INSP (category: experiments & observations)

Klimt in the Laboratory

After thermal annealing, the thin gold layer deposited on top of the Si substrate migrated and concentrated on some regions forming presumably gold crystallites but leaving behind uncovered Si islands and creating a beautiful “Klimt effect”.

One dimensional Helium continuum state

This is the bielectronic wave-function of a doubly ionized state of a one-dimensional system modeling Helium. This wave-function was calculated by inverse iteration performed on the Hamiltonian in a simulation box for an energy of 2.2 eV.

Generation of radio waves in the interplanetary medium

Fast particles are emitted during solar flares and propagate from the Sun outwards. During their propagation in the solar-wind plasma, they excite electron plasma waves which through several three-wave processes decay into radio waves. The theoretical and numerical study of these mechanisms together with spacecraft measurements of these waves, help us to understand the energy flux of fast particles from the Sun to the Earth. This is very important to examine the impact of these particles on industrial infrastructures both on the Earth and on satellites.


Photo competition 2016


1st Prize: Anna Levy, INSP (category: experiments & observations)

Anna's contribution shows gold nanoparticles used for femtosecond laser-irradiation experiments observed by SEM.



1st Prize: Andrea Sgattoni, LULI/LESIA (category: numerical simulation)

Andrea is a postdoctoral fellow, his contribution shows 3D Particle In Cell simulation of a thin dense plasma slab deformed and accelerated by light pressure. Electron density in red vs Ion density in blue highlight the target deformation, the imprints of the laser fields and the rise of instabilities.

Photo competition 2014

1st Prize: Romain Mayrand, LPP

Post doctoral fellow at the LPP, Romain's contribution is named Helcaraxe. It shows a beautiful representation of turbulence in a magnetized plasma using MHD simulation. The colors represent the intensity of the electric current in a plane perpendicular to the mean magnetic field.
