热中子和超热中子是探测水或高压氢气的有力探测器，因为它们与质子的散射截面很大。激光驱动的中子源能够同时发射不同类型的辐射，如X射线，可以在同一激光激发下用于中子和X射线照相。在本文中，我们报道了用激光驱动的热中子源对不锈钢管道内的水进行无损检测的演示，其中水和不锈钢容器分别用中子和X射线检测。仿真结果表明，该方法还具有测量金属容器高压氢气中氢气密度的能力。
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 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 this paper, we report the demonstration of non-destructive inspection for H2O contained within 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 can also provide the capability to measure the hydrogen density in high-pressure hydrogen gas in metal containers.
