N2 - GPTAS is a general-purpose unpolarized neutron triple-axis spectrometer installed at the port 4G of the Japan Research Reactor 3 (JRR-3), Tokai, Japan. GPTAS has been an indispensable instrument to investigate structural and magnetic properties of condensed matters, such as strongly-correlated-electron systems, frustrated magnets, quantum spin systems, quasicrystals, liquids, and so on. After the restart of the JRR-3, it has mainly contributed to the observation of weak magnetic reflections in many systems. In addition, it has also revealed the nature of structural or magnetic excitations, owing to the high efficiency increased by doubly focusing monochromator and analyzer. Recent studies using GPTAS are highlighted with on-going upgrades such as installation of two-dimensional position-sensitive detector.
