This facility at 6-BM-B is one of the spiritual successors to the X17MAC facility at NSLS-I, which ceased operations in late 2014. The 6-BM-B multi-anvil program was created in response to the “dark period” created by the closure of the NSLS facility in order to carry on the research programs that had been developed as part of the X17MAC portfolio. This program was best known for the development of high pressure and high temperature experimental deformation/rheological techniques and in situ ultrasonic interferometry experiments at extreme conditions. This legacy continues here with the further development of these and other experimental techniques to expand the range of possibilities in high pressure studies.
The 6-BM-B Beamline at the Advanced Photon Source (APS), Argonne National Laboratory, is a bending magnet "white beam" beamline utilizing energy dispersive X-ray diffraction and X-radiographic imaging techniques primarily in mineral physics and earth materials studies. This beamline is a dedicated high pressure multi-anvil facility equipped with a 250-ton hydraulic press with DIA, Deformation-DIA, and T-cup pressure modules, a Canberra 10-element Ge solid state detector array, and a Prosilica CCD camera for radiographic imaging. This beamline provides experimental capabilities for studying materials under hydrostatic and deformation conditions and is uniquely suited for studies of dynamic phase transformations, equations-of-state, melting processes, steady-state and dynamic rheological properties, as well as transport, thermal, elastic, and acoustic properties. This facility was built in February 2015 and has been open to COMPRES affiliated users in United States and abroad since the 2015-2 beam cycle.
