High pressure neutron diffraction. Present and future possibilities using the Paris-Edinburgh cell

The Paris-Edinburgh cells have been used over the past few years to obtain fully refinable neutron diffraction patterns by time-of-flight measurements on large volume powder samples up to 10 GPa at ambient temperature. The use of this type of instrument can be extended to i) higher pressures, well. above 20 GPa, ii) experiments at low and high temperature iii) the study of samples which are liquids or gases at ambient, and iv) to the study of single crystals in the angular dispersive mode.
