Portable apparatus for loading turnbuckle pressure cells with high pressure gases

Abstract

For high pressure work on high-purity metals that are very susceptible to any degree strain resulting from non-hydrostaticity, we have developed a portable apparatus for loading high pressure gases into turnbuckle style anvil cells (such as sapphire ball or SiC, diamond or sapphire anvil). The apparatus can be used with conventional high pressure intensifier systems that operate at room temperature, avoiding issues associated with cryogenic loading of pressure media. It is designed with interchangeable inserts that match the different pin patterns and shapes used to fix the endcaps in the various turnbuckle cells that are used for studies in pulsed and dc magnetic field studies, Magic Angle Spinning Nuclear Magnetic Resonance (MAS NMR), Electron Magnetic Resonance (EMR) and X-ray.
