PLANET is the beamline dedicated for the high-pressure experiments. The operation has been started at JFY 2013, and now many users are coming to use. In this talk, we introduce the current state of the PLANET and the example of the structure analysis of disordered materials. PLANET adopted the double staged compression system of the multi anvil 6-6, and enables the data collation at 10 GPa and 2000 K. To extend accessible PT range, we newly introduce another compression system of multi-anvil 6-8, and succeeded in generating 16 GPa and 1273 K. In addition, the PLANET is designed so that we can analyze the structure of liquid under pressure. In the analysis, the program for liquid analysis developed at BL21 NOVA is used. Here, we briefly introduce the reliability of the results and the pressure evolution of the silica glass.

We recently constructed the diffractometer dedicated to high-pressure purpose at pulsed neutron source J-PARC. This beamline has the huge 6-axis multi-anvil press, which is good at generating high-pressure and high-temperature condition simultaneously. By developing devices to eliminate scattering from materials around the sample, such as a sample container, a heater, we can obtain very clear pattern even under high-PT condition. This enables us to analyze the PT dependence of the structure of amorphous solids and liquids with high quality. I will explain the performance of the beamline and the PT modification of SiO$$_2$$ glass.
