Proceedings ArticleDOI
Diffraction efficiency of radially-profiled off-plane reflection gratings
Drew M. Miles,James H. Tutt,Casey T. DeRoo,Hannah Marlowe,Thomas Peterson,Randall L. McEntaffer,Benedikt Menz,Vadim Burwitz,Gisela Hartner,Christian Laubis,Frank Scholze +10 more
TL;DR: In this article, the authors presented efficiency measurements made in the 0.3 -1.5 keV energy band at the Physikalisch-Technische Bundesanstalt (PTB) BESSY II facility for three holographically-ruled reflection gratings, two of which are blazed.
Proceedings ArticleDOI

Proceedings ArticleDOI
X-ray testing ATHENA optics at PANTER
Vadim Burwitz,Giuseppe Vacanti,Maximilien J. Collon,Nicolas M. Barrière,Marcos Bavdaz,Ivo Ferreira,Mark Ayre,Emily Tipper,Josef Eder,Elias Breunig,Gisela Hartner,A. Langmeier,K. Müller,Surangkhana Rukdee,Thomas Schmidt +14 more
TL;DR: In this article , the results obtained from tests performed at the PANTER x-ray test facility for the SPO MM-0050 that was produced to verify the latest optical performance (half energy width (HEW), effective area) of SPOs, supporting the ESA reviews of their optical performance.
