Description

The uploaded files contain the data from measurements of total hemispherical emissivities and absorptivities of various metallic materials at cryogenic temperatures (in some cases up to room temperature). There are two files for each measurement: a text file with the characteristics of a given sample together with the measured data plus a corresponding graphics file with the temperature dependence of the emissivity or absorptivity. There is also a list of all measurements available in a single Microsoft Excel spreadsheet as well as in a PDF file. The spreadsheet file summarizes all the measurements and enables to filter the presented data with respect to a specific criterion.

Steps to reproduce

We performed the measurements and processed the collected data according to the method described in our earlier paper: Method for measurement of emissivity and absorptivity of highly reflective surfaces from 20 K to room temperatures Tomáš Králík, Věra Musilová, Pavel Hanzelka, Jiří Frolec Metrologia vol. 53 issue 2 (2016) pp: 743-753 DOI: 10.1088/0026-1394/53/2/743
