Abstract
We will report on the current status of SIKA, the triple-axis spectrometer with the view of the cold source from the reactor beam hall in OPAL, at ANSTO. SIKA is funded by the National Science Council of Taiwan and currently being commissioned by the National Synchrotron Radiation Research Center. To provide the flexibility for scientific applications, SIKA’s analyser can operate in a flat or in a multiplexing mode when coupled to the one-dimensional PSD consisting of 48 vertical position-sensitive wires, allowing the simultaneous data collection over a specified range in (Q, E). This analyser can also operate in a horizontal focusing mode that directs the scattered neutrons into a single-detector. The entire analyser-detector system as is packed into a single, well shielded secondary spectrometer housing which significantly reduces the background. As a state-of-the-art triple-axis spectrometer, SIKA is also equipped with a full automated sample stage and a series of collimations (both soller and radial). Neutron polarisation will be available for the incident and scattered beams through 3He polarisers.
