Abstract

A recent experiment, in which the production of cosmic strings in the early universe is modelled by the creation of quantised vortices in a fast expansion of liquid 4He through the lambda (superfluid) transition, is reviewed. Possible ways of redesigning the experiment to reduce extraneous vortex creation, and to enhance the signal-to-noise ratio at early times after the expansion, are discussed.
