The cell is made from a copper beryllium alloy and sized to fit into ORNL’s magnets for future ultra-low temperature and high-field studies. Large single-crystal synthetic diamonds have also been used for the first time with such a clamp-diamond anvil cell for pressures close to 20 GPa. Hydrostaticity and the important absence of shear pressure gradients have been established with the use of glycerin as a pressure medium. These anvils allow ~30%-40% taller samples than possible with comparable single-crystal anvils. Compared to earlier prototypes, pressure stability of polycrystalline diamond (Versimax®) has been increased through double-conical designs and ease of use has been improved through changes to seat and piston setups.

A simple spring design improves portability across the facilities and affords load maintenance from offline pressurization and during temperature cycling. It is adapted for work at several of the single-crystal diffractometers of the Spallation Neutron Source and the High Flux Isotope Reactor at the Oak Ridge National Laboratory (ORNL). In this paper, a diamond cell optimized for single-crystal neutron diffraction is described.
