Název v původním jazyce

Low conductive support for thermal insulation of a sample holder of a variable temperature scanning tunneling microscope

Popis výsledku v původním jazyce

We have designed a supporting system to fix a sample holder of a scanning tunneling microscope in an UHV chamber at room temperature. The microscope will operate down to a temperature of 20 K. Low thermal conductance, high mechanical stiffness, and smalldimensions are the main features of the supporting system. Three sets of four glass balls placed in vertices of a tetrahedron are used for thermal insulation based on small contact areas between the glass balls. We have analyzed the thermal conductivityof the contacts between the balls mutually and between a ball and a metallic plate while the results have been applied to the entire support. The calculation based on a simple model of the setup has been verified with some experimental measurements. Incomparison with other feasible supporting structures, the designed support has the lowest thermal conductance.
