Regeneration experiments below 10K in a regenerative-cycle cryocooler [PDF]

, 1983
At temperatures below 10K, regenerative cycle cryocoolers are limited by regeneration losses in the helium working fluid which result from the decreasing heat capacity of the regenerating material and the increasing density of helium.
