Neutron Intensity

Small angle neutron scattering (SANS) virtual experiment using silicon dioxide (SiO2) target has been performed. The results showed neutron flux with 1 million neutrons per count from the source in the range of 1.02x108n/s/cm2 and wavelength 5 Å. The neutron intensity was found to decrease after scattered at 1.75x105n/s/cm2 by nuclei in SiO2. We are able to construct a virtual experiment layout of Malaysian Small Angle Neutron Scattering (mySANS) facility using Monte Carlo simulation of neutron instruments (McStas).

ABSTRACTWe present small angle neutron scattering data of porous glasses. Analysis of the structure factor shows that the morphology on length scales between 30 A and 800 A depends on fabrication procedures. Fast gelation leads to a clumpy glass, whereas slow gelation produces a random smooth internal interface.

Monte Carlo Techniques

An introductory account of using molecular simulations to deduce solution structure of macromolecules using small angle neutron scattering data is presented for biologists. The presence of a liquid solution provides mobility to the molecules, making it difficult to pin down their structure. Here a simple introduction to molecular dynamics and Monte Carlo techniques is followed by a recipe to use the output of the simulations along with the scattering data in order to infer the structure of macromolecules when they are placed in a liquid solution. Some practical issues to be watched for are also highlighted.
