SMV-2019-09: New materials for cryogenics
Králík, Tomáš
The aim of the study was evaluation of the emission of thermal radiation emitted from a set of five commercially available foils which thermal radiative properties unknown till now. These materials are used for insulations of low temperature devices for medicine, industry or space exploration. The emissivity of the materials was measured at conditions truly simulating its operational environment. The measurement was done in a dedicated apparatus cooled with liquid helium. The emissivity of the sample was measured in vacuum at temperatures in the range from 20 K to 300 K.
