ANSTO's research capabilities, led by the OPAL nuclear research reactor and associated instruments provide access to users investigating areas as diverse as materials, life sciences, climate change and mining/engineering.
Simulation
There is increasing demand for computational tools to aid in the design of neutron-scattering instruments and experiments. The Monte-Carlo method is being used at ANSTO to assess optical components in our instruments and assist in the optimisation of guides and spectrometers.
The following Monte-Carlo simulation programs for Neutron Scattering and Synchrotron Radiation are available via the Internet:
- McStas (Neutron - from Riso National Laboratory, Denmark)
- NISP (Neutron - from Los Alamos National Laboratory, USA)
- JBS (Synchrotron - from the Elettra Synchrotron, Italy)
The following images are McStas Monte-Carlo simulations for the neutron beam coming through different apertures. In this case, the neutron beam divergence is a critical parameter in the design of a reflectometer at HIFAR.
