Abstract: Temperatures below 10* K can be achieved operating on a GiffordMcMahon cycle by the utilization of a thermal regenerator having a pressure-regulated helium reservoir positioned within an annulus circumferentially disposed about a helium refrigerant flow channel. Thermal conduction between the cyclically flowing helium refrigerant and the helium reservoir is effected by a plurality of porous metallic plates disposed at a perpendicular attitude relative to the refrigerant flow stream with adjacent plates being separated by thermal insulators, e.g. plastic rings, bonded to the plates to inhibit longitudinal thermal conduction in the regenerator. Preferably the bonded rings are concentrically disposed to form external sidewalls defining the helium refrigerant flow channel and to contain the helium reservoir. Because the helium heat reservoir is situated at a location remote from the channel wherein the helium refrigerant flows, the heat capacity of the reservoir can be varied by adding or removing helium from the reservoir without adversely effecting the helium refrigerant flow through the regenerator.
Abstract translation: 通过使用具有压力调节氦储存器的热再生器，可以在吉福德 - 麦克马洪循环上实现低于10K的温度，该压力调节氦储存器位于围绕氦制冷剂流动通道周向设置的环形空间内。 周期性流动的氦制冷剂和氦气储存器之间的热传导是通过多个多孔金属板来实现的，所述多孔金属板相对于制冷剂流动流以垂直的姿态设置，其中相邻的板被热绝缘体分隔，例如。 塑料环，结合到板上以抑制再生器中的纵向热传导。 优选地，接合环同心地设置成形成限定氦制冷剂流动通道并包含氦储存器的外部侧壁。 因为氦气储存器位于远离通道的位置，其中氦制冷剂流动，所以可以通过从储存器中添加或去除氦来改变储存器的热容量，而不会不利地影响通过再生器的氦制冷剂流。
