Finalized model (BGI manufacturing) of the new cell featuring its compact geometry and available apertures enabling diffraction and spectroscopic measurements in uniaxial and radial geometries.

In order to address specific challenges of the modern experiments at low temperature conditions involving backscattering equipment, we designed, produced and tested a new diamond anvil cell. Test of the cell involved measurements of partial phonon density of states for pure Te and Te oxide systems within nuclear inelastic scattering methodology. The cell was also tested and used for EXAFS, radial X-ray diffraction experiment producing supplementary information important for characterization of systems explored.
