Frank Seiboth,Andreas Schropp,Maria Scholz,Felix Wittwer,Felix Wittwer,Christian Rödel,Christian Rödel,Martin Wünsche,Tobias Ullsperger,Stefan Nolte,Jussi Rahomäki,Karolis Parfeniukas,Stylianos Giakoumidis,Ulrich Vogt,Ulrich Wagner,Christoph Rau,Ulrike Boesenberg,Jan Garrevoet,Gerald Falkenberg,Eric Galtier,Hae Ja Lee,Bob Nagler,Christian G. Schroer +22 more
TL;DR: In this article, the authors present accurate at wavelength measurements of residual aberrations of a refractive X-ray lens using ptychography to manufacture a corrective phase plate.
Journal ArticleDOI
Ptychographic characterization of a coherent nanofocused X-ray beam
Alexander Björling,Sebastian Kalbfleisch,Maik Kahnt,Simone Sala,Karolis Parfeniukas,Ulrich Vogt,Dina Carbone,Ulf Johansson +7 more
TL;DR: The NanoMAX hard X-ray nanoprobe is the first beamline to take full advantage of the diffraction-limited storage ring at the MAX IV synchrotron and delivers a high coherent photon flux for applications in diffraction and imaging.
Journal ArticleDOI
Reaction control of metal-assisted chemical etching for silicon-based zone plate nanostructures
TL;DR: In this paper, metal-assisted chemical etching (MACE) reaction parameters were investigated for the fabrication of specially designed silicon-based X-ray zone plate nanostructures using a gold catalyst pattern and etching solutions composed of HF and H2O2.
Journal ArticleDOI
Improved tungsten nanofabrication for hard X-ray zone plates
Karolis Parfeniukas,Jussi Rahomäki,Stylianos Giakoumidis,Frank Seiboth,Felix Wittwer,Christian G. Schroer,Ulrich Vogt +6 more
TL;DR: In this paper, an improved nanofabrication method of high aspect ratio tungsten structures for use in high efficiency nanofocusing hard X-ray zone plates was presented.
Proceedings ArticleDOI
First x-ray nanoimaging experiments at NanoMAX
Ulrich Vogt,Karolis Parfeniukas,Tomaš Stankevič,Sebastian Kalbfleisch,Marianne Liebi,Zdenek Matej,Alexander Björling,Gerardina Carbone,Anders Mikkelsen,Ulf Johansson +9 more
TL;DR: NanoMAX as discussed by the authors is a hard x-ray nano-imaging beamline at the new Swedish synchrotron radiation source MAX IV that became operational in 2016, which takes full advantage of MAX IV's exceptional low emittance and resulting coherent properties.
