Design and Manufacture an Elastic Neutron Scattering Spectrometer at the Dalat Nuclear Reactor ()
ABSTRACT
The
objective of this study is to design an elastic neutron scattering system according to the angle
with a sample using thermal neutron beam at the Dalat Nuclear Reactor (DNR). The system is used for research and training in
the field of material structure
analysis by neutron scattering and diffraction techniques. It is designed on the
basis of inheriting the neutron measurement spectrometer systems at the DNR and
the scattered neutron measurement systems in the world. The measuring system,
which was installed at the horizontal
channel 4 of the DNR, consists of 5-helium-3 detectors and a
fully electronic system to record the scatter counts and a mechanical system with the possibility of rotating at 15˚-75˚ angles. The constructed system is tested for evaluation of the accuracy, stability and
reliability of the mechanical and electronic systems of moving detectors by angles.
