    The TAIPAN thermal triple-axis spectrometer at the OPAL reactor
    (Australian Institute of Physics, 2006-12-05) Danilkin, SA; Horton, G; Moore, R; Hagen, ME
    Inelastic neutron scattering is a widely used technique to study phonon and magnon excitations in condensed matter and the triple axis spectrometer (TAS) is one of the main instruments used for such inelastic neutron scattering studies. As consequence the TAIPAN TAS will be the first inelastic instrument at the new Australian research reactor OPAL. It will be located on a thermal neutron beam tube at the reactor shielding face and can be operated either in a high flux mode with a double focusing monochromator and analyser, or in a traditional mode of operation with Soller collimators providing high resolution. A polarisation analysis capability will be realised on TAIPAN using supermirror benders. The spectrometer is currently under fabrication and should be commissioned at the beginning of 2007. We present the design and expected performance of the instrument.

    TAIPAN – a spectrometer for inelastic neutron scattering at the replacement research reactor
    (Australian Institute of Physics, 2004-02-04) Hagen, ME; Horton, G; Moore, R; Braoudakis, G; Cussen, LD
    Inelastic neutron scattering is widely used to study the lattice vibrational (phonon) and magnetic (spin wave and crystal field) excitations in condensed matter. In order to characterise such excitations comprehensively measurements on single crystal specimens are required and the most appropriate instrument for doing this at a steady state (reactor) neutron source is a three-axis spectrometer (TAS). We will describe the characteristics of the three axis spectrometer TAIPAN, which is currently under construction at the replacement research reactor, ANSTO and which will be available to the Australian scientific community in 2006.

    Thermal triple-axis spectometer at OPAL Reactor
    (Australian Institute of Physics, 2006-02-07) Danilkin, SA; Horton, G; Moore, R; Braoudakis, G; Hagen, ME
    Inelastic neutron scattering is widely used to study the excitations such as phonon and magnon in condensed matter. A triple–axis spectrometer (TAS) is one of main instruments used in neutron scattering studies. TAS TAIPAN will be the first inelastic instrument at the Australian research reactor OPAL. It will be placed at a reactor face position and will use double focusing monochromators and analyser. In addition to the double-focusing regime, TAIPAN will have a standard mode of operation with Soller collimators providing high resolution. The instrument will use supermirror benders for polarization analysis.
