Overview

Large volume presses allow one to perform high pressure and high temperature diffraction experiments on mm-sized samples with excellent T and P stability and uniformity up to 40 GPa and 3000 K.

l Phase equilibrium studies with in-situ pressure and temperature determination
l Time resolved experiments on kinetics of reactions with sub-second data collection
l Strength and rheological properties of minerals, viscosity of liquids and melts
l P-V-T equation-of-state measurements with better P, T coverage, precision, and accuracy
l Simultaneous measurements of density and acoustic velocities for absolute equation of state

l High pressure tomography, equations of state of glasses and melts

l High resolution crystallography. Powder x-ray structural refinements. Structures of glasses and melts
l System designed to be compatible with multi-anvil devices existing in high pressure labs world wide

l Interchangeable tooling for wide range of experiments
l On-site machine shop and synthesis facilities
l On-site data analysis

Hydraulic presses and support frames

2.5 MN (250 ton) press in station 13-BM-D. Four different high-pressure modules, DIA, D-DIA, T-Cup and the tomography apparatus (see below) can be used, with either energy-dispersive or angle-dispersive diffraction techniques. Radiographic imaging also available.

A 5-axis detector support is used for the Ge solid state detector for energy dispersive diffraction using the 250 ton LVP. Diffraction can be performed either in the vertical plane for the DIA or an inclined plane (35.3 deg.) for the T-Cup.

The 10 MN (1,000 ton) LVP (A) in 13-ID-D held by the positioning support base (B). The window - frame press is 1 m (W) x 2 m (Ht) x 0.6 m (Th) and weighs 6 tons. Roller table (C) for transport various guide blocks into the press. Positive displacement pump (D) is used for fine pressure control. Incident X-rays are collimated by motorized WC slits mounted on slit stand (E), and diffracted signals received by a detector mounted on a multi-purpose detector support (F- see picture below for details).

A five-degree freedom detector support for the 10 MN LVP, designed for both energy-dispersive AND monochromatic diffraction using single or multi-element solid-state detectors, scintillation devices, imaging plates, and CCD. Shown here are configurations of a seven-element detector at the DIA (left) and T-Cup (right) mode.
