(Partial) Perforations |
Perforated anvils |
Diamond backing plates have the following advantages: |
|
- Substantial reduction in background for all types of radiation(IR, visible, UV or x-rays).
- Substantial reduction in the interfering "red" light fluorescing from diamonds at P>100 GPa.
- Substantial savings in price due to small anvil weight(W ~ 0.02 .C)
|
Holes are laser-drilled in the form of a truncated cone. The base diameters are to fit the dimensions/apertures of the carbide backing plates |
 |
Parameters can be made according to your requirements. |
Partially perforated anvils from the table side

A perforated diamond anvil cell for high-energy x-ray diffraction of liquids and amorphous solids at high pressure. (Published online: 29 March 2010, Review of sicentific instruments 81, 035110 (2010)) Emmanuel Soignard, Chris J. Benmore, and Jeffery L. Yarger |
The DAC presented in this article is designed to study amporphous materials at high pressure using high-energy x-ray scattering (>60 keV) using laser-perforated diamonds.A small diameter perforation maintains structural
integrity and has allowed us to reach pressures > 50 GPa, while dramatically decreasing the intensity of the x-ray diffraction background (primarily Compton scattering) when
compared to studies using solid diamonds. This cell design allows us for the first time measurement of x-ray scattering from light (low Z) amporhous materials. Here, we present data for two examples using the described DAC with one and two
perforated diamond geometries for the high-pressure strucural
studies of SiO2 glass and B2O3 glass.
