Abstract (en)
[origin: EP2312239A2] The cooler has first and second compound pulse tube cooling units (1.1, 1.2) whose first and second warm ends (4.1-4.4) are connected with expansion chambers (9.1-9.4) of third and fourth pulse tube cooling units (1.3, 1.4) by line expanders (14.1-14.4). The compound pulse tube cooling units are connected with each other. The warm ends of the first and second cooling units move pistons (16.1-16.4) of compressors (15.1-15.4) together with a phase shift of 360 degrees. Linear drives (6.1-6.4) are driven by 4-phasecurrent.
