Abstract
A cell with unsupported beveled sapphire-anvils was developed to carry out small-angle neutron scattering measurements in large-volume liquid samples up to a pressure of 530 MPa. The body of the anvil is a cylinder with a 30 mm diameter. One end is shaped into a truncated cone with a face 14 mm in diameter. The two opposed anvils squeeze a flat metallic gasket of thickness between 1 and 3 mm with a central hole between 4 and 10 mm in diameter. The initial sample volume varies from about 10 to 240mm3. The highest achievable pressure depends on the dimensions and on the mechanical properties of the gasket. To allow a high neutron transmission of the collimated neutron beam, a 10-mm-diam bore is machined along the cell axis. For a neutron beam of 7 mm in diameter, the maximum forward scattering angle is about 9.5°. With a neutron wavelength of 0.4 nm, this allows scattering spectra to be recorded for wave-number transfers up to 2.6nm−1.
