Multistage thermoelectric La(Ce)B6 cryocoolers

Abstract

Using finite element modeling based on the COMSOL package, we analyzed the static and dynamic performance of a multistage cryocooler, the coldest stage of which is constituted of thermoelectric legs. Using published data on the achievable parameters of lanthanum-cerium hexaborides, we modeled a single and double-stage thermoelectric cooler. Estimates are also provided for an N-stage cooler. The results can be used for practical realization of additional cooling stages for reaching temperatures below 1.8 K in commercially available cryostats.
