Overview
The neutron user facilities at ORNL use and develop a wide range of high pressure cells and devices that are available to the user program through the High Pressure Group, the High Pressure Diffractometer SNAP, through collaborative efforts with the Institute of Solid State Physics at the University of Tokyo, as part of the US-Japan Cooperative Program on Neutron Scattering, as well as through individual beamline efforts.
Typical cell volumes and pressure ranges afforded by the various pressure cells in use with ORNL’s neutron scattering program.
Cell types, corresponding sample geometries and sizes, pressure media and pressure application are typically optimized for given instrument geometries and science questions. They can be loosely grouped into these seven different general types. Please refer to the individual tabs for details:
- Cylindrical gas pressure cells and gas intensifiers
- Gas flow and other gas dosing devices
- SANS gas pressure cells
- Clamped piston-cylinder cells
- Uniaxial pressure devices
- Paris-Edinburgh cells
- Diamond anvil cells
- Mechanical Loading
