Abstract

A neutron radiography technique that can be used to map the distribution of ³He impurities in liquid ⁴He, providing direct and quantitative access to underlying transport processes, was analyzed. Images reflecting finite normal- and superfluid-component ⁴He velocity fields were described. The essential features of an experimental technique that allows to generate high-resolution images of impurity distributions and velocity fields in superfluid liquid ⁴He seeded with minute quantities of ³He were demonstrated. It was found that neutron-detected tomography provides an excellent probe for monitoring impurity distributions, for studying heat transfer, and for mapping hydrodynamic velocity fields.
