Thermal neutron (∼25 meV) beam is a powerful tool for investigating the structure and properties of materials used in science and technology. A laser-driven neutron source generating 1010 neutrons within 1 ns duration is utilized to a single shot radiography with a dual beam of thermal neutrons and X-rays. As a proof of principle, we show the non-destructive inspection of hazardous substances (Cadmium) contained in a typical battery, when the cadmium anode thickness is evaluated from the transmittance of thermal neutrons. The fact that the neutron inspection above is performed with a single laser shot, i.e. with a single bunch of neutrons leads to a safer neutron source that is optically controlled on/off, and provides a novel tool for science and engineering.

用明亮的激光驱动热中子和 X 射线源进行单次射线照相

热中子(~25 meV)束是研究科学技术材料结构和性能的有力工具。在 1 ns 持续时间内产生 10 10 个中子的激光驱动中子源被用于具有热中子和 X 射线双束的单次射线照相。作为原理证明,我们展示了对典型电池中含有的有害物质(镉)的无损检测,当镉阳极厚度从热中子的透射率评估时。上述中子检查是用单次激光发射(即用一束中子)执行的事实导致更安全的中子源,该中子源由光学控制开/关,并为科学和工程提供了一种新工具。
