20.500.12556/RUL-152366 A parallel-beam wavelength-dispersive X-ray emission spectrometer for high energy resolution in-air micro-PIXE analysis A new parallel-beam wavelength dispersive (PB-WDS) X-ray emission spectrometer was constructed at the external proton beamline at the Microanalytical Centre of the Jožef Stefan Institute in Ljubljana. The spectrometer combines polycapillary X-ray optics for efficient X-ray collection with diffraction on a flat crystal analyzer and achieves energy resolution in the eV range. The whole set-up is enclosed within a He bag to be able to operate in the tender X-ray energy range. The basic design is described together with the results of characterization measurements yielding the main operation characteristics. Finally, an application for the micro-PIXE analysis of biological tissue is demonstrated exploiting both spatial and energy resolution of the new set-up. parallel beam wavelength dispersion X-ray emission spectrometer characteristics micro-PIXE analysis true false true Angleški jezik Ni določen Članek v reviji 2023-11-22 14:40:29 2023-11-22 14:40:33 2023-11-23 03:39:05 0000-00-00 00:00:00 2023 0 0 Str. 1164-1172 iss. 5 Vol. 38 May 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 543.2/.9 1364-5544 10.1039/d3ja00019b 150748931 d3ja00019b.pdf d3ja00019b.pdf 1 C135ABC21D33BC66D39B39A7524356EE 259f70478d795329bfa8509a730860ce9e59d632cdcd4027058c9776ffbdace0 f9d6ce8b-893c-11ee-916c-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=177851 https://pubs.rsc.org/en/content/articlelanding/2023/JA/D3JA00019B 0 dd8471d3-893c-11ee-916c-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=177850 Fakulteta za matematiko in fiziko Biotehniška fakulteta 0 0 0
