Abstract
This work highlights the design and characterization tests of different strap prototypes in order to achieve the necessary resistivity and thermal conductivity for low cryogenic temperatures. In cryogenics, working together with cryocoolers, the thermal straps are a critical thermal element, since they thermally link the instrument with the cold source. In optical elements that work at low temperatures, the thermal path, and therefore the straps, must isolate them from the vibrations of the cryocoolers. Consequently, the thermal strap stiffness is an important characteristic to consider in the design.
