Abstract

Diamond anvil cells allow static pressures on small samples up to a few hundred GPa. The anvils also serve as an optical window to the sample. Although the anvils are rather transparent for most types of radiation, the absorption of γ- or soft x-rays in a few mm of diamond can prevent or seriously degrade the quality of the Mössbauer spectrum. Using smaller (thinner) diamonds helps, but then the ultimate pressure suffers. Several schemes are proposed and tested to reduce the pathway (absorption) by drilling away most of the anvil in the axial path, yet retaining its strength and stability.
