Abstract
The newly-built high resolution neutron diffractometer (HRND) at China Academy of Engineering Physics (CAEP) could not acquire high-quality diffraction patterns. In order to solve the problem, the present work introduces the Monte Carlo method based software called Geant4 which is rarely applied in the field of neutron diffraction. The geometrical structure of HRND has been structured by Geant4, thus simulation results can not only re-display the problems of HRND but help to solve such problems as well. According to the simulation results, some effective measures have been carried out to obtain higher instrument performance. It is found that the performance of HRND is improved eventually after new experimental diffraction patterns are acquired.
