Je parlerai tres brievement de l'ALP ions par CSA sur jets de gaz denses: experiences LULI + GSI. je presenterai nos conclusions concernant l'optical shaping et nos projets

12. Un étude numérique des réactions de fusion proton-bore

Un étude numérique des réaction de fusion proton-bore : simulations interpreting and describing all involved physical processes. The main mechanism consists in producing energetic laser-driven protons inducing the generation of α-particles in a secondary boron target : pitcher-catcher geometry. The multiple code use is required : pedestal effects can be performed with 2D hydrodynamics codes...

Generating low divergence beams is one of the major challenges the laser-plasma ion acceleration community faces since the seminal TNSA works from two decades ago. We have recently generated at the Salle Noire facility in LOA proton beams with unprecedented low divergence (3 degrees FWHM, up to 100 pC and 0.48 MeV), directly from a simple rotating glass target, at kHz repetition rate. I will...

14. Confrontation simulation/expérience d'accélération de protons par TNSA sur le laser PETAL

Proton energies as high as 51 MeV have been measured significantly above those expected from preliminary numerical simulations using idealized interaction conditions. Multidimensional hydrodynamic and kinetic simulations, show the importance of the energetic electron production in the extended low-density preplasma created by the laser pedestal. This hot-electron generation occurs through two...
