Outline
A hydraulic opposite anvil system (HAL-11) consisting of an inner anvil cell, a hydraulic loading system, and an alignment system, is developed for high pressure in-situ neutron diffraction. The inner anvil cell can be compatible with various anvils with different culet sizes and materials, such as WC, sapphire, SiC, and sintered polycrystalline diamond. A maximum load up to 500 kN can be provided by the hydraulic loading system through a hydraulic jack with hand pump, and the pressure decline caused by the rheology of gasket and specimen can be compensated during the high pressure in-situ neutron diffraction experiments. The opposite anvil system attached on a four dimensional pensile-type translational stage is aligned by means of two lasers, and the entire system can be easily assembled and distributed. The pressure calibration results show that the sample pressure is above 12 GPa with WC anvils at a loading force of about 150 kN.
