ID06-LVP - Large Volume Press

ID06LVP is dedicated to the data collections, in angle-dispersive mode, from large-volume samples under high pressure and temperature conditions. The press is a modified cubic device with independent U and D rams and 20MN total force available. Typical applications are from solid-state chemistry and synthesis to the Earth sciences. We use a lightly-modified lab-based sample assembly with 32, 26, 1", 25, 14 mm cubes, most commonly with 10/4, to reach pressures in excess of 20 GPa and 2000 K, using graphite, Ni, TiB2 or rhenium furnaces. Other octahedra/truncation combinations are supported; from 25 mm to 2 mm. We use a range of carbides (TF05, ha7, 6uf, etc) for a range of applications. Monchromatic energies are offered, usually, though not exclusively, at 33 keV and 55 keV. Other data collection strategies are available for deformation (6 & 6/6) and 1-stage compression studies using sintered diamond anvils. Experiments may be complemented by other techniques; resistivity, ultrasonics, &c. The beamline is particularly suited to time-resolved studies and those where rapid evaluation of phase space is required; experiments are real time with detectors running at 10 Hz or faster per full 2TH dataset. Deformation measurements take advantage of full azimuthal scans in under 1 minute. Ultrasonic readout is 12sec per frequency.

Machining and sample prep available onsite

Description

Two workshops are available for Users. They host: two Roland milling machines, a lathe, a pillar drill, diamond wheels, hand press, welder for the machining of assembly parts and preparation of thermocouples and capsules. They also have two binocular microscopes at workstations for mounting and dissecting run products.  Space is made for epoxy mounting. Cutting, grinding and polishing of samples (etc) also possible. We have two ovens, one constant 60 deg and one vacuum to 200degC. All necessary hand and precision tools can be provided for successful prep and mounting of samples and for subsequent analysis.
