Laser-driven neutron source, which is able to simultaneously emit different types of radiations such as X-rays, can be used for neutron and X-ray radiography in the same laser shot. In the present paper, we report the demonstration of non-destructive inspection for H2O inside of a stainless steel pipe using a laser driven thermal neutron source, where water and stainless containers are detected by neutrons and X-rays, respectively. The simulation result indicates that this method is also able to measure accurately the hydrogen density in high-pressure hydrogen gas in metal containers.}, title = {Non-destructive inspection of water or high-pressure hydrogen gas in metal pipes by the flash of neutrons and X-rays generated by laser}, volume = {12}, year = {2022} }
