Enhanced electron injection for efficient proton acceleration and neutron production in femtosecond laser-driven nano-structured targets
Yingzi Dai, Chengyu Qin, Hui Zhang, Guoqiang Zhang et autres
Micro- or nano-structured targets are advantageous in enhancing and manipulating laser-proton acceleration, due to the increased absorption of laser energy and onset of direct laser acceleration for high-energy electrons. Here, we experimentally demonstrate that nano-wire-array printed on a flat substrate is an …
