Spatial and temporal view in microscopic level−Neutron scattering−
Determination of the static arrangement of atoms and spins and their dynamical behavior is the most important toelucidate the mechanism of interested physical phenomena. Neutron scattering technique provides us a precise
understanding of them thorough its ability for wide spatial and temporal regimes. We, Tohoku University, manage threeneutron instruments installed at the research reactor JRR-3 and develop a state-of-the-art polarized neutron spectrometer
at J-PARC, and hereby provide unique opportunities for neutron scattering experiments utilizing these instruments(abbreviated as PATH). Please use them for your own research on a wide range of fields such as from crystal structure
analysis of energy-based materials including light elements to magnetic excitations in strongly correlated electron systems.

PATH to truth

PATH is a collective term for neutron instruments managed by Tohoku University. HERMES can
precisely determine the arrangement of atoms and spins, and their motions are examined by
POLANO, AKANE and TOPAN. They are properly used for interested energy and momentum
transfer regimes. In addition, POLANO and TOPAN equip polarized option and can disentangle
nuclear and magnetic contributions. PATH is operated by Center of Neutron Science forAdvanced Materials at Institute for Materials Research, Tohoku University, and we aim tocontribute to condensed matter physics and materials science with multi-purposed neutron
instruments.
* Institute for Solid State Physics, University of Tokyo will call for proposals in JRR-3.
* Construction and operation of POLANO is carried out jointly with KEK.

How to use
Neutron instruments installed at JRR-3 are operated based
upon joint use, and will be open in the end of FY2020 after reoperation of JRR-3. Polarized neutron spectrometer POLANO atJ-PARC/MLF, now at the final stage of construction, will be inservice after the commissioning. Staff members in IMR will
support your use, please feel free to ask the following contacts.
