ABSTRACT
An optical high pressure cell has been constructed of spherical sapphire anvils (9.53 mm in diameter). The anvil has a small fiat compression face ( 1.5 mm or 2.5 mm in diameter), which is perpendicular to the crystal c axis. Pressure is generated using a gasket, typically made of phosphorus bronze. A maximum pressure of 12.6 GPa was generated at room temperature in a liquid pressure medium. Pressures up to 10 GPa have been generated stably without appreciable damage of the anvils. The capability of optical observations for a photon energy region up to 6.4 eV was confirmed with this anvil, at high pressure. An advantage of the spherical anvil is ease in production.
