A. Schropp,A. Schropp,Robert Hoppe,Vivienne Meier,Jens Patommel,Frank Seiboth,Hae Ja Lee,Bob Nagler,Eric Galtier,Brice Arnold,Ulf Zastrau,Jerome B. Hastings,Daniel Nilsson,Fredrik Uhlén,Ulrich Vogt,Hans M. Hertz,Christian G. Schroer +16 more
TL;DR: This article demonstrates focusing of hard X-ray FEL pulses to 125 nm using refractive x-ray optics, and reports on the full characterization of a nanofocused XFEL beam by ptychographic imaging, giving access to the complex wave field in the nanofocus.
Journal ArticleDOI

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
A 9 keV electron-impact liquid-gallium-jet x-ray source
TL;DR: A high-brightness compact 9 keV electron-impact microfocus x-ray source based on a liquid-gallium-jet anode suitable for laboratory-scale x-rays crystallography and hard x-Ray microscopy is demonstrated.
Journal ArticleDOI
Compact x-ray microscope for the water window based on a high brightness laser plasma source
Herbert Legall,G. Blobel,Holger Stiel,Wolfgang Sandner,Christian Seim,Per Takman,Dale Martz,M. Selin,Ulrich Vogt,Hans M. Hertz,Dominik Esser,H. Sipma,Jörg Luttmann,M. Höfer,Hans-Dieter Hoffmann,S. Yulin,T. Feigl,Stefan Rehbein,Peter Guttmann,Gerd Schneider,U. Wiesemann,M. Wirtz,W. Diete +22 more
TL;DR: A laser plasma based x-ray microscope for the water window employing a high-average power laser system for plasma generation and the exposure time can be further reduced to 20 s by the use of new multilayer condenser optics.
Journal ArticleDOI
New diamond nanofabrication process for hard x-ray zone plates
Fredrik Uhlén,Sandra Lindqvist,Daniel Nilsson,Julia Reinspach,Ulrich Vogt,Hans M. Hertz,Anders Holmberg,Ray Barrett +7 more
TL;DR: In this article, a tungsten-hardmask-based diamond dry-etch process was proposed for fabricating diamond zone plate lenses with a high aspect ratio. But the results were limited to a scanning microscope arrangement showing sub-100nm resolution.
