Recent upgrades to ANSTO's thermal triple axis spectrometer 'TAIPAN'

The thermal triple axis spectrometer, TAIPAN, has been operational since 2010 and employs a graphite monochromator to access neutron energy transfers up to 80meV. A recent string of projects have greatly increased the capabilities of this instrument. Initially the wall shared with the cold TAS, SIKA, was modified to allow access to larger regions of Q-Energy space for TAIPAN. A more recent upgrade project has involved developing a new sapphire filter translation stage mechanism and a new Cu-200 double-focussing monochromators. The copper monochromator has been installed back to back with the previous highly ordered PG-monochromator and extends the accessible energy range of the neutrons from 70meV to 180meV.
