报告内容：

The demonstration of ignition and further progress at the National Ignition Facility have validated inertial fusion as a viable approach to Inertial Fusion Energy (IFE) and have triggered many initiatives and large investments.         In Europe the HiPER+ initiative started in about 2020 [1] as a bottom-up proposal stemming from the academic community, dedicated to the study of direct drive, as the most promising route to civilian electricity generation from laser fusion due to the increased energy efficiency and coherence with the required high repetition rate implementation, with respect to indirect drive. Recently HiPER+ has been endorsed and funded by Eurofusion [2] with the goal of providing a conceptual design for a future European implosion facility. 30 research groups from 12 different European countries participate in the project currently funded for 2026 and 2027, thereby assembling the vast majority of the laser-plasma and inertial fusion community in Europe. 

 In addition to the technological and industrial challenges related to developing a reactor concept based on inertial fusion, we must advance knowledge of the physics of direct-drive laser-plasma interactions and implosions, in particular with reference to the shock ignition approach. 

 In this context the research groups involved in HiPER+ are performing an intense experimental and theoretical activity. The talk will present some of the experimental and theoretical results obtained in European and overseas large-scale laser facilities, in particular related to: 

1、Laser-plasma interaction at intensities of interest for direct-drive and shock ignition. We performed experiments at the PALS and ELI-beamlines laser facilities in Prague to investigate the growth of side and back stimulated Raman scattering (SSRS and BSRS) in inhomogeneous plasmas, highlighting the importance of SSRS and its relations with the generation of hot electrons [3]; 

 2、Use of foam materials as a tool for mitigating the non-uniformities of laser energy deposition. Study of shock generation and shock propagation in foams. Study of the equation of state of foam materials. Use of foams for improved laser-driven secondary sources of radiation and particles [4]; 

 3、Study of the equation of state of materials which could be used as ablators for implosion experiments in alternative to synthetic diamonds, specifically boron compounds [5]; 

 4、Development of advanced diagnostics for direct-drive, encompassing those for shock propagation and target hydrodynamics (such as X-ray Phase-Contrast Imaging), particle spectroscopy and identification [6].
