Small angle neutron scattering using a triple axis spectrometer
- Atomic Energy Research Establishment, Dhaka (Bangladesh)
SANS technique has been developed on a triple axis neutron spectrometer at TRIGA Mark II (3 MW) research reactor, AERE, Savar, Dhaka, Bangladesh. Double crystal (with very small mosaic spread {approximately} 1 min.) diffraction known as Bonse and Hart`s method has been employed in this technique. Such a device is a useful tool for small angle scattering in the Q range between 10{sup -5} and 10{sup -1} {Angstrom}{sup -1} and for real time experiments at short time scales. Therefore, large objects and large distance interparticle correlations can be investigated easily by this method. Test measurements using alumina (Al{sub 2}O{sub 3}) sample has been carried out to exploit this method. The radius of gyration has been determined and the data has been fitted to the scattering function of a sphere.
