Description
With the development of Nano-Micro-array (NMA) fabrication, intense laser-irradiated NMAs have been proposed to produce brilliant gamma-rays and high-yield positrons with appealing conversion efficiency. In this presentation, we introduce how to emply a laser-irradiated NMA scheme to produce brilliant attosecond gamma-ray flashes and high-yield positron bunches with high conversion efficiency. We further introduce an enhanced generation of α particles in laser-irradiated NWAs composed of hydrogen-containing boron nitride. The underlying proton-boron fusion plamsa physics is also introduced. We conclude that the schemes using NMAs would provide effective avenues toward investigating attosecond nuclear science and HED physics with the available 10 PW laser facilities.
