The PLANET is the new high-pressure neutron beamline constructed at the intense pulsed neutron source J-PARC. This beamline aims at revealing the effect of water on dynamics of the interior of the Earth and planets by using the neutron character that is sensitive to hydrogen. The most characteristic feature of this beamline is to possess the huge 6-axis press with the maximum load of 500 ton/axis, which can simultaneously generate high-pressure and high-temperature condition of 20 GPa and 2000 K (see Sano-Furukawa et al.). Coupled with the state-of-the-art techniques of neutron diffraction and radiography, the beamline offers the microscopic and macroscopic information of materials at high-PT condition. In the last Spring, we finished the beam commissioning. I introduce the general feature of this beamline and the specification revealed by the commissioning. The beamline is used by the project members before the next March, and then it will be opened for general users.
