The design of 2/8-type high-pressure cell applied to in situ neutron diffraction

论文摘要

The DIA-type Kawai cell possesses a larger volume and a quasi-hydrostatic pressure environment and has been widely used in materials’ synthesis and x-ray diffraction experiments.However, few high-pressure in situ neutron diffraction experiments were performed in the DIA-type Kawai cell because there is no wide window for neutron diffraction and the second-stage anvils and guild block material attenuates the neutron signal significantly.In this work, we tentatively modified the normal DIA-type Kawai cell（MA 2-6-8） into a MA 2-8 mode by removing the six first-stage tungsten carbide anvils.As a consequence, the eight tungsten carbide anvils（Kawai cell） are directly driven by the guide blocks.The results of ex situ and in situ pressure calibration show that the cell pressure can reach 5 GPa with small truncation edge lengths（TEL） of 3 mm even at the load of 300 kN.It suggests that this MA 2-8 cell may open a new way for high-pressure and high-temperature in situ neutron diffraction.
