PLANET is the neutron beamline dedicated to high-pressure experiments in J-PARC. One of most characteristic features is its ability to conduct diffraction measurements simultaneously at high pressures and high temperatures up to 24 GPa and 1200 K, respectively. Another characteristic feature is its ability to collect clean pattern without parasitic scattering from materials around sample by defining the diffraction gauge volume with narrow incident slits and radial collimators with a field of view of 0.8-3.0 mm at the sample position. This enables precise structure determination not only of crystals but also of liquids and amorphous solids. Furthermore, it also enables the use of smaller samples, which contributes to increase maximum available pressure. In this presentation, the performance and recent developments of the beamline will be introduced along with recent scientific results obtained at PLANET.
