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. 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.
