Naukowcy z Deutsches Elektronen-Synchrotron (DESY) opracowali soczewki, kt\u00f3re potrafi\u0105 skupi\u0107 promieniowanie rentgenowskie do ogniska o \u015brednicy mniejszej ni\u017c 10 nm. Soczewki s\u0105 zrobione z element\u00f3w sk\u0142adaj\u0105cych si\u0119 z dziesi\u0105tk\u00f3w tysi\u0119cy bardzo cienkich (~ 2 nm) warstw zbudowanych na przemian z w\u0119glika krzemu (SiC) i z w\u0119glika wolframu (WC). Warstwy s\u0105 produkowane technik\u0105 napylania i s\u0105 wykonane z niezwykle du\u017c\u0105 precyzj\u0105.<\/p>\n
W publikacji, kt\u00f3ra zosta\u0142a ju\u017c zaakceptowana do druku [1], kt\u00f3rej wsp\u00f3\u0142autorem jest dr hab. Andrzej Andrejczuk, pracownik Wydzia\u0142u Fizyki, zademonstrowano, \u017ce przy u\u017cyciu dw\u00f3ch liniowych soczewek wykonanych opisan\u0105 technik\u0105 udaje si\u0119 skupi\u0107 promieniowanie rentgenowskie o energii foton\u00f3w 16,3 keV do ogniska o rozmiarach 8,4 x 6,8 nm. Przy u\u017cyciu tak skupionej wi\u0105zki promieniowania technik\u0105 skaningow\u0105 zobrazowano pierwotniaka kolcon\u00f3\u017cki (Acantharia). Mo\u017cna s\u0105dzi\u0107, \u017ce je\u017celi dodatkowo poprawi si\u0119 jako\u015b\u0107 soczewek, b\u0119dzie mo\u017cna uzyska\u0107 ognisko o \u015brednicy ~ 1 nm.<\/p>\n
