Compression techniques
A variety of techniques are available to compress macroscopic samples of matter to high pressures in excess of 100 GPa (1 million atmospheres), including:
- laser-driven mass ablation ("direct drive")
- thermal x-ray drive ("indirect drive")
- pulsed power ("magnetic drive")
- gas gun impactors
- diamond anvil cell [DAC] ("static" compression)
In some cases, combinations of the above can be fielded, such as laser drive of DAC-compressed samples. See also our facilities page.
Diagnostic and analysis techniques
- shock-wave impedance matching
- optical reflectivity and thermal emission spectroscopy
- ramp wave analysis
- x-ray absorption fine structure [XAFS] and x-ray absorption near-edge structure [XANES]
- x-ray diffraction [XRD]
- x-ray radiography
- proton radiography
