Säm Krucker,Säm Krucker,Steven Christe,Lindsay Glesener,Shin-nosuke Ishikawa,Brian D. Ramsey,Tadayuki Takahashi,Shin Watanabe,Shinya Saito,Mikhail Gubarev,Kiranmayee Kilaru,Hiroyasu Tajima,Takaaki Tanaka,Paul Turin,Stephen McBride,David Glaser,Jose Fermin,Stephen M. White,Robert P. Lin +18 more
TL;DR: The Focusing Optics X-ray Solar Imager (FOXSI) as discussed by the authors was the first sounding rocket payload to produce the first focused images of the Sun above 5 keV, which demonstrated the superiority in sensitivity and dynamic range that is achievable with a direct HXR imager with respect to previous, indirect imaging methods.

TL;DR: The International X-ray Observatory (IXO) as mentioned in this paper is designed to conduct spectroscopic, imaging, and timing studies of astrophysical phenomena that take place as near as in the solar system and as far as in early universe.

TL;DR: The Focusing Optics X-ray Solar Imager (FOXSI) sounding rocket payload flew for the second time on 2014 December 11 and provided the first HXR focused images of the Sun.
Journal ArticleDOI
Differential deposition technique for figure corrections in grazing-incidence x-ray optics
TL;DR: In this paper, a differential deposition technique was investigated as a way to minimize axial figure errors in full-shell, grazing-incidence, reflective x-ray optics using a combination of off-axis conic segments-hyperbolic, parabolic, and/or elliptical.
Journal ArticleDOI
Optimal alignment of mirror based pentaprisms for scanning deflectometric devices
Samuel K. Barber,Ralf D. Geckeler,Valeriy V. Yashchuk,Mikhail Gubarev,Jana Buchheim,Frank Siewert,Thomas Zeschke +6 more
TL;DR: The analytical derivation and verification of easily executed optimal alignment algorithms for two different designs of mirror based pentaprisms are provided and an analytical description for the mechanism for reduction of the systematic errors introduced by a typical high quality bulk pentaprism is provided.
