Materials Science and Condensed Matter Physics on PATH Triple-Axis Spectrometers AKANE and TOPAN.

The Institute for Materials Research at Tohoku University has a long history of neutron research and has contributed to the research community since the beginning of neutron science in Japan. The Center of Neutron Science for Advanced Materials, established in 2010, manages three neutron instruments (powder diffractometer HERMES, high-momentum resolution three-axis spectrometer AKANE, and polarized neutron three-axis spectrometer TOPAN) in Japan Research Reactor JRR-3. These instruments, along with the chopper spectrometer POLANO constructed jointly with the High Energy Accelerator Research Organization at the Materials and Life Science Experimental Facility, are named PATH from the initial characters of each name. In this paper, we introduce the advantages of the PATH platform for neutron beam utilization and present the overview of the two spectrometers at JRR-3, showcasing the possible measurements that can be conducted on these spectrometers. Representative results obtained using the AKANE and TOPAN spectrometers are also presented to promote neutron scattering experiments to general users. Furthermore, we outline our current and future plans for instrument upgrades to advance our research in magnetism, a primary focus of our ongoing and upcoming investigations. [ABSTRACT FROM AUTHOR]
