Abstract
Method of reliquefying gaseous helium produced when transferring liquid helium from a donor container (R1) to a receiver container (R2), characterized in that a stream of gaseous helium is bled off from a point in a compression unit (10) intended for charging with gaseous helium under pressure, this stream of gaseous helium is cooled by heat exchange with the gaseous helium intended for the compression unit (10) and the compressed gaseous helium thus cooled is expanded in order to obtain reliquefied helium.
