泛欧洲极端光基础设施(ELI-NP)面向核物理的支柱将容纳一个超亮、能量可调和准单色伽马射线束系统，该系统由激光康普顿背向散射产生，范围为0.2-19.5 MeV。这种伽马束满足大尺寸产品研究的标准，增加了通过使用核共振荧光(NRF)进行同位素检测的能力，是无损检测应用的理想选择。在ELI-NP设想了伽马束的两个主要应用：基于NRF的工业应用和工业射线照相和断层照相。这两种应用都利用了伽马束的独特特性，为该行业带来了新的机遇。在这里，我们介绍了在ELI-NP上提出的实验装置，并基于解析计算和GEANT4数值模拟讨论了它们的性能。在ELI-NP使用伽马束用于基于NRF的应用的主要优点之一是可以获得先进的探测器阵列，这可以增强伽马束的高质量已经提供的优势。
The Nuclear Physics oriented pillar of the pan-European Extreme Light Infrastructure (ELI-NP) will host an ultra-bright, energy tunable, and quasi-monochromatic gamma-ray beam system in the range of 0.2–19.5 MeV produced by laser Compton backscattering. This gamma beam satisfies the criteria for large-size product investigations with added capabilities like isotope detection through the use of nuclear resonance fluorescence (NRF) and is ideal for non-destructive testing applications. Two major applications of gamma beams are being envisaged at ELI-NP: industrial applications based on NRF and industrial radiography and tomography. Both applications exploit the unique characteristics of the gamma beam to deliver new opportunities for the industry. Here, we present the experimental setups proposed at ELI-NP and discuss their performance based on analytical calculations and GEANT4 numerical simulations. One of the main advantages of using the gamma beam at ELI-NP for applications based on NRF is the availability of an advanced detector array, which can enhance the advantages already provided by the high quality of the gamma beam.
