Cryostat insert with gas loading capabilities for use in neutron diffraction studies

Abstract

We describe a versatile insert for use with the “Standard Orange cryostat” commonly found at neutron scattering facilities worldwide. Its design permits condensable gases to be introduced into a low-temperature sample cell through a vacuum-insulated, fill-line capillary. It also allows the top-flange-to-sample-cell distance to be easily adjusted and provides for auxillary heating of the fill-line capillary.
