Research can be carried out at a wide range of temperatures from 173 K to 573 K and in high vacuum reaching 10\u207b\u2076 bar. The measurement results provide information on the size and distribution of free volume in polymers, as well as the pore size in microporous materials within the range of r<sub>h<\/sub> \u2248 1.5 \u00c5 to r<sub>h<\/sub> \u2248 100 \u00c5. The research technique also enables the characterization of defect structures, including the detection of crystalline structure defects in metallic materials. The laboratory is also equipped with a scanner for measuring \u03b1, \u03b2, \u03b3 and X-ray radiation levels.<\/p>\n<\/div>\r\n                    <\/div>\r\n                <\/div>[\/vc_tta_section][vc_tta_section title=&#8221;Equipment&#8221; tab_id=&#8221;1645113822678-51a69647-60ce&#8221;]\r\n                <div class=\"text-modules\">\r\n                    <div class=\"container\">\r\n                        \r\n                        <div class=\"text-modules__content\"><\/p>\n<ul>\n<li><strong>Positron lifetime spectrometer<\/strong> with a chamber for temperature-controlled measurements, equipped with a vacuum pump allowing a vacuum level of 10\u207b\u2076 bar to be achieved.
