摘要: 在中国散裂中子源反角白光终端,测量了中子能量为33.9MeV 12C(n,d)x的角微分反应截面。利用轻带电粒子探测器阵列(LPDA)E-E 望远镜系统, 测量了在实验室坐标系下从24.5到155.5 12C(n,d)x 的角微分反应截面。实验结果能够很好的符合以前的实验结果。由于缺少实验数据,这项工作为相关数据库的评价及数据库研制提供了重要参考。

摘要: Shanghai Laser Electron Gamma Source (SLEGS) is a powerful gamma source to provide MeV gamma-ray beams for nuclear science and technology. It is developed as one of the sixteenbeamline stations in Phase II Project of the Shanghai Synchrotron Radiation Facility (SSRF). Theslant-scattering mode is for the first time systematically employed in the laser Compton scattering (LCS) at SLEGS to produce energy-tunable quasi-monoenergetic gamma-ray beams. SLEGS officially completed its commissioning from July to December 2021. Gamma-rays in energy range of 0.25 - 21.7 MeV with the flux of 2.1 104 - 1.2 107 photons/s and the energy spread of 2 15 % are produced during the test. This paper reports results of the commissioning of the SLEGS beamline.
