The technical development for the high-pressure and temperature neutron diffraction with six-axis large volume press, ATSUHIME, which has been installed at BL11 (PLANET) in J-PARC, is introduced. The 6-6-type assembly is one of suitable module for high-pressure neutron diffraction due to wide accessibility to the sample. In order to apply the 6-6-type assembly to the high-pressure neutron diffraction, large 6-6-type anvils (including anvils tightening by steel jacket) and the cell assembly have been designed and tested. The test compression and heating experiments demonstrated the usability of the large 6-6-type assembly. Future challenge is how high-intensity signal from sample can be ensured at high pressure.
