Beamline: F2.1

The MAX80 (Multi Anvil Type X-Ray System) is a multi-anvil high pressure apparatus with six tungsten carbide anvils compressing a cubic sample-volume. Pressure is generated by a 250-ton hydraulic ram and measured by adding an internal pressure marker with known PVT-data to the sample. The maximum temperature of approx. 2000 K is produced by an internal graphite heater and controlled by thermocouples. The attainable pressure is mainly determined by the edge length of the anvil faces: approx. 7 GPa with an edge length of 6 mm and approx. 12 GPa with 4 mm edge length. The high pressure cell is a cube made of a mixture of boron and epoxy resin containing the cylindrical sample. The sample volume can be changed according to the demand of the experiment and the amounts can be realized between 20 mm³ and 5 mm³.

Present applications are:

stability of minerals under high pressure and temperature
determination of bulk moduli
thermal expansion
phase diagrams
kinetic measurements
