GeoSoilEnviroCARS (GSECARS) is an earth-science-driven X-ray synchrotron facility at the Advanced Photon Source of the Argonne National Laboratory. As a national user facility, we provide users with access to the high-brilliance hard X-rays from this third-generation synchrotron light source. The multi-anvil, large-volume high-pressure facility at the bending magnet beamline (13-BM-D) runs a unique setup permitting an unusually wide range of high-pressure and high-temperature experiments combined with X-rays and other in-situ probing techniques. It has been a great asset for the high-pressure earth science community since its inception in 1997. A series of upgrades and updates occurred in the 2010s. Here we provide a detailed description of the current large-volume press (LVP) setup at 13-BM-D, including hardware, software, and all experimental capabilities. Examples of scientific studies that were performed at GSECARS utilizing the new LVP system are also reported.

Overall view of the nine-axis custom design high-precision motion system that is located inside the bending magnet beamline hutch 13-BM-D.
Setup for imaging in the LVP system. The incident beam (yellow line) passes through the anvil gaps and the cell assembly and impinges on the Ce:LuAG scintillator crystal, which converts X-rays to visible light (red line).
a) Reconstructed 3-D tomography image of the examined graphic granite sample (5.7 mm × 5.8 mm × 5.4 mm). Quartz grains are shown in light color, while the dark color represents the feldspars.
b) Quartz grains with different crystallographic orientations inside the single crystal feldspar observed under cross-polarized light.
c) View perpendicular to the mid-plane cross-section. Cross sections A–A’ and B–B’ show that most of the quartz grains run continuously, sub-parallel to the vertical axis
