Summary

A transportable cryogenic apparatus has been developed for both neutron scattering and phase equilibrium studies on supercritical inert gas mixtures. It centers on a stirred, batch, view cell of unique design. By changing three parts of simple design (two windows, one sample cylinder), this apparatus can be used to study wide or small angle scattering of neutrons or X-rays. Its use can be extended to pure fluids, liquids, and states away from the critical point. It operates within pressure and temperature ranges of 0-13.8 megapascals and 20-300 K. The accuracy and performance of the apparatus was tested on pure neon by reproducing its saturation curve and by performing small angle neutron scattering on some supercritical states.
