is an acronym for US-Japan Cold Neutron Triple Axis Spectrometer, a
crystal spectrometer which uses a continuous neutron beam.
developed as a collaborative effort of scientists from the leading US National
Laboratories and an international group of prominent neutron scattering experts,
aimed at designing and building a new high-flux inelastic neutron spectrometer
at the new Cold Guide Hall of the High Flux Isotope Reactor at Oak Ridge. This
effort is led by the physicists from the
Neutron Scattering Group (and former Center for Neutron Science) at
Brookhaven National Laboratory. The USJ-TAX is part of the US-Japan
Cooperative Program on Neutron Scattering, including scientists of the Neutron
Scattering Science Division at Oak Ridge National Laboratory, the Neutron
Scattering Group at BNL, and the
Neutron Science Laboratory, Institute for Solid State Physics, at the
University of Tokyo.
cold neutrons entered the new Cold Guide Hall of the
Flux Isotope Reactor
Oak Ridge National Laboratory (ORNL) in Tennessee in 2007 and HFIR has
demonstrated reliable operation with many cycles since. This Cold Source is the
brightest source of cold neutrons in the world, opening exciting new
opportunities for use in scientific research and industrial development.
The USJ-TAX is an inelastic
cold neutron spectrometer optimized for studying single crystal samples in a
broad variety of sample environments. It is intended to supply users of the HFIR
and the scientific community with a platform for ground-breaking investigations
of the low-energy atomic-scale dynamical properties of crystalline solids. It is
planned that USJ-TAX will be commissioned in 2009.
