Summary

The aim of this work is to evaluate the influence of indium thermal interface 100 μm thick on the thermal contact resistance between copper cylindrical samples with a diameter and height of 15 mm. These copper samples (moving and stationary) represent a model of a mechanical thermal switch for use in magnetic cooling. The experiment was carried out inside a cryostat in a temperature range from 15 to 140 K and an ambient pressure of 1.1×10-2 – 4.5×10-3 Pa and external magnetic field up to 3 T. The contact force of pressing copper samples with an indium thermal interface was 300 kPa.
