极端光基础设施-核物理设施将于2018年在罗马尼亚布加勒斯特-马古雷莱开始提供具有高光谱密度和高度偏振的明亮伽马光束。提出了几种用于测量γ束的光谱、时间和空间特性的监测仪器。在美国达勒姆的高强度γ源上进行的一系列测量中，研究了d（γ，n）p反应在确定γ束参数中的应用。已使用液体闪烁体和6Li-玻璃中子探测器在几个入射伽马能量在2.5至20 MeV之间的测量发射的中子。本文的实验结果表明，基于d（γ，n）p反应的仪器可以用来监测ELI-NP产生的γ束的强度和偏振。
The Extreme Light Infrastructure - Nuclear Physics facility will deliver brilliant gamma beams with high spectral density and a high degree of polarization starting in 2018 in Bucharest-Magurele, Romania. Several monitoring instruments are proposed for measuring the spectral, temporal, and spatial characteristics of the gamma beam. The d(γ,n)p reaction has been investigated for its use in determining the gamma beam parameters in a series of measurements carried out at the High Intensity Gamma Source, Durham, U.S.A.. Measurements of the emitted neutrons have been performed using liquid scintillator and 6Li-glass neutron detectors at several incident gamma energies between 2.5 to 20 MeV . The experimental results presented in this paper have shown that an instrument based on the d(γ,n)p reaction can be used to monitor the intensity and polarization of the gamma beam to be produced at ELI-NP.
