Abstract / Description of output

We report the design of a compact sapphire anvil cell for small angle neutron scattering. Based on turnbuckle-opposed anvil technique, the dimensions of this cell are minimized for use with a small-bore magnets using finite element analysis. This cell is the smallest sapphire anvil cell to date. The cell body is approximately 14 mm diameter cylinder and 13 mm length, the overall length of the assembled cell is less than 17 mm. Inside the cell, two spherical-shaped sapphire anvils are used to ensure compactness and anvil’s strength, and at the same time to provide sufficient sample volume for a neutron scattering experiment. The sample volume of the cell used in the SANS experiment was as large as 0.4 mm 33 , which is approximately 40 times larger than the conventional diamond anvil cell. The cell has been used in a SANS study of a niobium single crystal at D22 Institut Laue-Langevin with the maximum pressure of 4 GPa being achieved with the liquid pressure medium. During the tests the cell demonstrated that it was capable of achieving pressure to 6 GPa with a powder sample.
