Talk

Recent progress in instrumentation at neutron sources is also enabling innovation in high pressure neutron scattering. Together with pressure cell development, advances are driven by increased neutron flux, improved beam focusing and alignment capabilities. At the Spallation Neutron Source (SNS) of Oak Ridge National Laboratory (ORNL) we use these advances to push the limits in high pressure...

30. High-pressure total scattering using neutrons

Talk

The majority of neutron total scattering experiments have been performed under ambient or variable-temperature conditions whereas comparatively little work has been carried out under high pressure. This is partly a consequence of the difficulties involved in accurately removing non-sample scattering contributions when using devices such as the Paris-Edinburgh press, which are required to...

40. In situ mechanical uniaxial pressure devices for SINQ and SμS facilities at PSI

Talk

Uniaxial pressure is emerging as a powerful experimental tuning parameter for quantum materials that can be employed with various experimental techniques. In recent years, the sample environment capabilities of PSI’s neutron facility SINQ have been enriched by the adoption of the 200 N in situ uniaxial pressure device [1]. Its mechanical transmission rod allows the user to accurately measure...

36. Time-domain Brillouin scattering for 3D-imaging of texture, phase transitions, elastic and plastic properties of solids compressed in a diamond anvil cell

Dr Andreas Zerr (LSPM-CNRS)

Talk

Time-domain Brillouin scattering (TDBS) technique uses ultrafast laser pulses to generate coherent acoustic pulses (CAPs) and monitor their propagation through transparent samples. Local velocity of a CAP along depth of a sample (V_A, where A represents longitudinal (L) or transversal (T) sound velocity) is extracted from oscillating intensity of the probe light scattered by the...

31. Recent advances on the SNAP diffractometer

Christopher Ridley (Oak Ridge National Laboratory)

Talk

The SNAP diffractometer at the Spallation Neutron Source (Oak Ridge, TN) is unique in providing routine access to a diamond anvil cell (DAC)-based neutron diffraction program. These capabilities underpin SNAP’s broader micro-diffraction program, routinely handling sample volumes ranging from 0.03 to 0.3 mm3. This enables neutron diffraction studies of materials across a wide range of extreme...
