One picture says it all - High-pressure cells for neutron Laue diffraction on VIVALDI

Possible applications of the neutron single-crystal Laue diffraction technique with a large image-plate detector to high-pressure studies are examined. One opposed-piston cell with a Ti-Zr casing is shown to be acceptable for medium pressures. For higher pressures a moissanite-anvil cell with reasonably large accessibility is shown to offer impressive gains in data collection rate as compared to the monochromatic technique. Moreover, the projected forms of the reflections from the sample and anvils facilitate alignment, and the wide wavelength band of the Laue technique allows recovery of reflections masked by the cell pillars, simply by rotation of the cell.
