“…Based on the life test of other models of the same design (Table 4), CMC fully anticipates that the life of the B5000 cooler will exceed 10,000 hours. CMC is actively pursuing to extend the life of our coolers through material selection, life predictions [13,14], contamination studies [15,16], and new designs (including pulse tube [17,18] and flexure bearings [17]).…”

We have successfully developed and qualified a 5-Watt Stirling cryocooler that is suitable for commercial applications in the high temperature superconductor (HTS) wireless communication systems. The cooldown time to 77 K is less than 5 minutes (with 4 Watts heat load and a thermal mass of 1465 Joules). The cooler can provide a refrigeration capacity of ~5 Watt at 70 K. The qualification and test results of this cooler are discussed. FIGURE 1. A photograph of the B5000E Cooler.
