Perspectives on research on laser driven proton-boron fusion and applications

Abstract Recent experiments with high-intensity lasers have shown record production of α -particles by irradiating boron-hydrogen targets. This opened the way to completely new studies on proton-boron fusion multiple goals: i) related nuclear fusion. The reaction produces 3 and releases a large energy. It is considered an interesting alternative deuterium-tritium because it no neutrons, therefore activation radioactive wastes. ii) generation novel laser-driven -particle sources. Laser-driven α-particle sources are promising for their potential high brightness while remaining compact. They could be used multidisciplinary applications, including medical ones. COST Action CA21128 — PROBONO (PROton BOron Nuclear fusion: from energy applicatiOns) first international programme which aims at understanding physics involved in pB fusion, study Equation State boron compounds. Action's goals facilitate access experimental infrastructures, maximize knowledge, boost career young researchers fostering opportunities training, finally interconnect across countries building well-organized community focused research.
