Large Volume Paris-Edinburgh press program at 16-BM-B

At the experimental beamline 16-BM-B of the Advanced Photon Source, Argonne National Laboratory, we have established a set of capabilities for comprehensive high-pressure x-ray studies using a large volume press. The large sample volume press enables multiple experiment types that are not easily feasible with small volume devices like the diamond anvil cell, allowing to better investigate the relationship between the microscopic structure and the macroscopic properties of matter at high pressure (P) and high temperature (T) conditions. The beamline is equipped with a Paris-Edinburgh (PE) press, integrated with a multitude of x-ray techniques and other optical and ultrasonic techniques for in-situ characterization at high P-T conditions. The samples with dimensions of several millimeters can be simultaneously compressed and heated up to P of 7 gigapascal (GPa) and T of 2300 K. The established characterization techniques include ultrasound echo, falling sphere viscometry, monochromatic x-ray absorption scanning, phase contrast radiography, and specialty sample cells with electrical probes. Beamline description, recent developments, and science examples will be presented.
