The Multi Analyzer Neutron Triple-Axis (MANTA) instrument will provide critically needed, world leading capabilities for cold neutron spectroscopy for the quantum materials community. As a world-class cold triple axis spectrometer at HFIR, it will facilitate unique low-energy neutron spectroscopy experiments, capabilities that are highly in demand by the quantum materials community. MANTA is part of the planned HFIR beryllium reflector replacement project, so will come online with the completion of that project.

Phase I of the project will upgrade the primary spectrometer, adding a neutron velocity selector and incident beam polarization.  The current CTAX secondary spectrometer will be re-located to the MANTA guide for use as a conventional cold-neutron triple axis instrument. Phase II of MANTA will introduce an interchangeable multi-analyzer backend and will add spherical neutron polarimetry and Wollaston prism capabilities to the instrument that will be compatible with the single detector backend.
