Abstract
A pulse tube system especially useful for producing and delivering refrigeration at very cold temperatures wherein a product fluid such as hydrogen is preferably precooled and then liquefied, subcooled and/or densified by heat exchange with ultra cold gas generated by a pulsing compression wave which rejects heat into a cryogen fluid heat sink.
