In the cells the pressure can be continuously adjusted from 0 to Pmax while the sample is in the beam. The cell is linked via a flexible high pressure capillary to a gas pressure generator, or a high pressure piston pump, which can be located several meters away. The pressure transmitting medium can be helium gas or liquids like "fluorinert" (a fluorocarbon) , deuterated hydrocarbon or alcohol (such as iso-propanol). When null matrix Ti-Zr alloy is used for the cell body or gaskets, there is very little coherent scattering. The maximum sample dimensions varies with the cells and pressure ranges. These cells fit into a standard "Orange" cryostat. The ILL can supply a complete system including the dedicated pressure generator if required.

These pressure cells are available on request. Sufficient advance notice to sane(at)ill.fr is required for their reservation and preparation.
