Non-destructive inspection of water or high-pressure hydrogen gas in metal pipes by the flash of neutrons and x rays generated by laser

The thermal and epithermal neutrons are powerful probes to inspect water or high-pressure hydrogen gas because of their large scattering cross-sections with protons. Laser-driven neutron source, which is able simultaneously emit different types radiations such as x rays, can be used for x-ray radiography in the same laser shot. In this paper, we report demonstration non-destructive inspection H 2 O contained within a stainless steel pipe using laser-driven where containers detected by respectively. simulation result indicates that method also provide capability measure density metal containers.
