Description
Manipulating and filtering the neutron spin on neutron scattering instruments allows to extract unique insights on the properties of materials. Triple-axis spectrometers have proven to be one of the most flexible neutron scattering instruments to accommodate such experimental conditions. We will present the cold triple axis spectrometer Sika [1,2] and its capalibities for polarized neutron scattering experiment at the Australian Nuclear Science and Technology Organization (ANSTO). The National Synchrotron Radiation Research Center (NSRRC) in Taiwan has been responsible for operating this instrument, as per the agreement established between NSRRC and ANSTO. We will share the latest technical development and scientific achievements with polarized neutrons on Sika, such as identifying spin incoherent contribution to quasi-elastic neutron scattering (QENS) [3], identiying a weak ferromagnetic compoment of magengtic materials [4], determining the chirality of helimagnet, and so on.
