Laser-Plasma Interaction Experiment for Solar Burst Studies Open
A new experimental platform based on laser-plasma interaction is proposed to explore the fundamental processes of wave coupling at the origin of interplanetary radio emissions. It is applied to the study of electromagnetic (EM) emission at…
Characteristics of ion beams generated in the interaction of ultra-short laser pulses with ultra-thin foils Open
Experiments investigating ion acceleration from laser-irradiated ultra-thin foils on the GEMINI laser facility at the Rutherford appleton laboratory indicate a transition to ‘light sail’ radiation pressure acceleration when using circularl…
ALaDyn/ALaDyn: ALaDyn v2020.2 Open
Minor release Released a patch for the major version v.3.0.0. Bug fixed MPI Particle exchange when the moving window was activated now fully works. Parallelization along the longitudinal direction has been tested. Now code works also with …
ALaDyn/ALaDyn: ALaDyn v2019.1 Open
In this release, some known problems have been addressed and new features have been added. In particular: stretched grid on transvers axis is now available in a newer and tested version simulation dump and restart has been fully paralleliz…
Electromagnetic Simulations of Solar Radio Emissions Open
Solar radio emissions are electromagnetic waves emitted in the solar wind as a consequence of electron beams accelerated during solar flares or interplanetary shocks such as interplanetary coronal mass ejections. Different physical mechani…

Structured targets for advanced laser-driven sources Open
Structured targets offer great control over ultra-intense laser-plasma interaction, allowing the optimization of laser-target coupling for specific applications. By means of particle-in-cell simulations we investigated three applications i…
Polarization Dependence of Bulk Ion Acceleration from Ultrathin Foils Irradiated by High-Intensity Ultrashort Laser Pulses Open
The acceleration of ions from ultrathin (10-100 nm) carbon foils has been investigated using intense (∼6×10^{20} W cm^{-2}) ultrashort (45 fs) laser pulses, highlighting a strong dependence of the ion beam parameters on the laser polarizat…

Development of foam-based layered targets for laser-driven ion beam production Open
We report on the development of foam-based double-layer targets (DLTs) for laser-driven ion acceleration. Foam layers with a density of a few mg cm-3 and controlled thickness in the 8-36 μm range were grown on μm-thick Al foils by pulsed l…
Electron Acceleration by Relativistic Surface Plasmons in Laser-Grating Interaction Open
The generation of energetic electron bunches by the interaction of a short, ultraintense (I>10(19) W/cm(2)) laser pulse with "grating" targets has been investigated in a regime of ultrahigh pulse-to-prepulse contrast (10(12)). For incidenc…
