                                    Citation: N/AInterpretive Summary: The X-ray micro-Tomography Facility at the Advanced Light Source has been in operation since 2004. The source is a superconducting bend magnet of critical energy 10.5KeV; photon energy coverage is 8-45 KeV in monochromatic mode, and a filtered white light option yields useful photons up to 50 KeV. A user-friendly graphical user interface allows users to collect tomographic and radiographic data sets with options including tiled and time series data sets. We will focus on recent experiments made possible by our development of unique sample environments for in-situ imaging. These environments include an ultrahigh temperature tensile load frame rig which allows for the study of material failure under in situ uniaxial loading at temperatures up to 2300oC, a chamber to study water transport in living plants, and at high pressure triaxial flow cell which has allowed study of supercritical CO2 transport through brine-saturated sandstone at pressures typical of in-situ conditions for subsurface CO2 sequestration.
