From the point of view of fundamental physics, the underlying dynamics of laser-plasma interaction at ultrahigh field intensities and the acceleration of macroscopic quantities of matter towards GeV/nucleon energies represent unique examples of relativistic many-body systems which can be produced and studied in a small laboratory scales. The study of such systems are also challenging for theoretical and computational physics, due to the extremely nonlinear, collective dynamics and the typical multi-scale nature of the problems.
The present project aims at attaining major advances in this research field by a joint effort between two Italian research units, representing the most recognized national groups active in the theory and simulation of laser-plasma acceleration, and international partners which are leaders in experimental laser-plasma physics. This effort will include a wide theoretical and computational study of ion acceleration regimes, such as the Target Normal Sheath Acceleration and the Radiation Pressure Acceleration regimes, aimed at achieving a deeper understanding of existing experimental data, proposing and interpreting further experiments, and inferring the scaling of ion acceleration in near-future regimes of ultra-high intensities where major breakthroughs may be expected. In particular, a major part of the research will focus on the design, production and testing of micro- and nano-engineered targets whose characteristics will be tailored to optimize the production of energetic ions. This activity will involve and coordinate in an unprecedented way expertises from materials science and engineering with those from laser and plasma physics and computational science.
