The Multi-Anvil X-ray facility at the XPD-D (28-ID-2-D) Beamline of the National Synchrotron Light Source II (NSLS-II) is a new cutting-edge facility designed to push the limits of high pressure multi-anvil synchrotron research. The MAXPD (Multi-Anvil X-ray Powder Diffraction) facility is one of the spiritual successors to the X17MAC facility at NSLS-I, which ceased operations in late 2014. 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 MAXPD facility is located in the downstream D hutch on the XPD beamline, which is served by a 1.8T damping wiggler insertion device. The facility contains an 1100-ton hydraulic press with DIA, Deformation-DIA, T-25 (Kawai-style multi-anvil), and the first ever functional Deformation-T-25 compressional modules. MAXPD utilizes monochromatic X-Ray beam (usually 52 keV or 67 keV). The experimental setup makes use of a Point Gray Grasshopper 3 CCD camera focused on a YAG scintillator crystal to allow for imaging of the sample during experiments, and a Perkin-Elmer area detector for collection of angle-dispersive X-ray diffraction spectra. The MAXPD facility is in the process of developing an on-site fully equipped sample and experiment preparation laboratory that is maintained by beamline staff, as well as preparation facilities at Stony Brook University that are maintained and operated by the Mineral Physics Institute. These preparation facilities are/will be available to facility users.
