International audience; We present a new continuously-loaded high-pressure cell for neutron diffraction made from TiZr 'null-matrix' alloy that combines high mechanical resistance below 100 °C and negligible coherent neutron scattering. This cell operates at a maximum pressure of 700 MPa down to a temperature of 1.5 K. A sapphire optical window allows simultaneous illumination of the sample over the broad wavelength range ~0.4 to almost 5 μm. The pressure is applied with Fluorinert or helium gas to ensure the best possible hydrostatic conditions at cryogenic temperatures.
