Abstract： : Introduces the construction and trial operation of Shanghai Laser Electron Gamma Source (SLEGS) beamline station, one
of the Shanghai light source(SSRF) projects II, which can carry out basic research on nuclear physics and nuclear astrophysics, and
carry out applied research such as gamma irradiation, gamma imaging and gamma activation at SLEGS gamma source. The SLEGS
beamline station passed the process acceptance in December 2021, entered the trial operation stage in October 2022, and have open
to users in September 2023. SLEGS is the first in the world to use the continuous collision angle mode to change the energy of the
gamma beam, with the best energy scanning accuracy, flow intensity density and efficient energy regulation ability. In the trial
operation stage, the SLEGS beamline station focused on solving the problem of online monitoring of gamma beam energy spectrum
and flow intensity, mainly completed the experimental methodology research of optical neutron cross-section measurement by flat
efficiency spectrometer (FED), and carried out the expansion and research of application platforms such as gamma imaging, gamma
activation, and positron source generation. With the development of inverse Compton scattering techniques, short-pulse,
high-polarization, high-throughput, and miniaturized laser Compton scattering light sources will usher in better development
opportunities in the future, and will play an important role in nuclear physics, astrophysics, particle physics, polarization physics, as
well as aerospace, medical testing, energy development and other gamma source application research fields.

Abstract： The angle-differential cross sections of neutron-induced d production from carbon were measured at neutron energies 33.9 MeV at China Spallation Neutron Source (CSNS) Back-n white neutron source. By employing the ΔE-E telescopes of the Light-charged Particle Detector Array (LPDA) system at 24.5° to 155.5° in the laboratory system, the angle-differential cross sections of the 12C(n,d)x reactions were measured.
The experimental results are in good agreement with the previous ones.The present work can provide a reference to the data library considering the lack of experimental data.
