Conventional High Pressure Techniques for Neutron Diffraction

Abstract

Conventional high pressure techniques using a clamped type pressure cell have been adapted for studies by neutron diffraction. Careful calibration of the pressure sensing apparatus and an appropriate choice of pressure transmitting medium enable accurate neutron diffraction measurements to be made at reduced temperature as low as 4 K. In the present studies we have demonstrated that using the clamped type microbomb neutron diffraction measurements can be easily made under the pressure up to 5 kbar within the temperature range 4 K–350 K.
