Diamond anvil cells for neutron diffraction
High Pressure Research, 1995Abstract Design and general description of diamond anvil cells, developed for neutron diffraction studies of powder and single crystal samples, are given. Some aspects of high pressure neutron diffraction experiments are discussed.

Diamond-anvil uniaxial stress cell
Review of Scientific Instruments, 1996A diamond-anvil cell, normally used for generating high hydrostatic pressure, serves as an excellent uniaxial stress cell. We demonstrate this by using a standard cell to apply up to 6 kbar uniaxial stress, nearly twice the stress previously reported in the literature, to semiconductor laser diodes.

Ultrasonic measurements in a diamond anvil cell
Physics of the Earth and Planetary Interiors, 1996Abstract Advances in ultrasonic and electronic technology have made it practical to make elastic wave measurements with wavelengths which are near the optical range, i.e. in the micro meter range. Ultrasonic interferometry has been adapted to a diamond anvil cell and thus expands the tools available for material property measurements under high ...

New anvil designs in diamond-cells
High Pressure Research, 2004New diamond anvils with conical support are introduced. Compared to conventional anvils the new design offers superior alignment stability, larger aperture, and reduced cost owing to significantly smaller anvil diameters. Except for table and culet, all surfaces are precision ground on a lathe, which lowers cost compared to faceted anvils.

Whole-cell heater for the diamond anvil cell
Review of Scientific Instruments, 2003An external heating assemblage allowing diamond anvil cell (DAC) experiments at megabar pressures and temperatures above 1200 K was constructed. The complete high-pressure high-temperature system consists of an anvil assembly made from a special high-temperature alloy, a mechanical loading mechanism, and external resistive heaters placed around the ...

A diamond anvil cell for IR microspectroscopy
Review of Scientific Instruments, 1995A large optical-aperture membrane diamond anvil cell designed for infrared spectroscopy is described. The cell offers definite advantages compared to existing systems. Other possibilities concerning x-ray diffraction analyses with the cells are mentioned.

Magnetic stirrer for diamond-anvil cells
Physica B+C, 1986Abstract A continuing problem in the performance of high-pressure X-ray diffraction experiments with a diamond-anvil cell is that of interpreting the integrated intensity data. Two primary causes of this are the relatively small number of crystallites in the pressure cavity and possible preferred orientation effects. An electromagnetic attachment has

Recent Developments in Diamond-Anvil Cells
1993Diamond-anvil cells have been simplified and miniaturised to the point where they can be added with little difficulty to a wide range of experiments. This allows high pressure, or the control of interatomic spacing, to be more generally applied in solid state physics than hitherto.

Experimental Techniques in the Diamond Anvil Cell
1999The operating principles of diamond-anvil high pressure cells are reviewed, with particular attention to the implications for design and construction. The diamond culets and gasket generate the pressure, and their behaviour dictates the requirements for the rest of the cell.
