High-Resolution, Lightweight, and Low-cost X-Ray Optics for the Lynx Observatory
William W. Zhang,Kim D. Allgood,Michael P. Biskach,Kai-Wing Chan,Michal Hlinka,John D. Kearney,James R. Mazzarella,Ryan S. McClelland,Ai Numata,Raul E. Riveros,Timo T. Saha,Peter M. Solly +11 more
TL;DR: An approach to build an x-ray mirror assembly that can meet Lynx’s requirements of high-angular resolution, large effective area, light weight, short production schedule, and low-production cost is described.
Proceedings ArticleDOI
Coating thin mirror segments for lightweight x-ray optics
Kai-Wing Chan,Kai-Wing Chan,Marton V. Sharpe,William W. Zhang,Linette D. Kolos,Melinda Hong,Ryan S. McClelland,B. R. Hohl,Timo T. Saha,James R. Mazzarella +9 more
TL;DR: In this paper, it is shown that balancing the coating distortion either by coating films with tensile and compressive stresses, or on both sides of the mirrors is not sufficient and that heating the mirror in a moderately high temperature can relax the coated films reasonably well.
Proceedings ArticleDOI
Next generation astronomical x-ray optics: high angular resolution, light weight, and low production cost
William W. Zhang,Michael P. Biskach,Peter Blake,Kai-Wing Chan,Jessica A. Gaskin,Melinda Hong,William D. Jones,Linette D. Kolos,James R. Mazzarella,R. S. McClelland,Steve O'Dell,Timo T. Saha,Marton V. Sharpe +12 more
TL;DR: In this article, the authors report on the approach, strategy and status of the x-ray optics development program whose objective is to meet these technical challenges at modest cost to enable future X-ray missions, including small Explorer missions, probe class missions in the near term, and large flagship mission in the long term.
Proceedings ArticleDOI
Astronomical x-ray optics using mono-crystalline silicon: high resolution, light weight, and low cost
William W. Zhang,Kim D. Allgood,Michael P. Biskach,Kai-Wing Chan,Kai-Wing Chan,Michal Hlinka,John D. Kearney,James R. Mazzarella,Ryan S. McClelland,Ai Numata,Raul E. Riveros,Raul E. Riveros,Timo T. Saha,Peter M. Solly +13 more
TL;DR: In this article, an approach based on the precision polishing of mono-crystalline silicon to fabricate thin and lightweight X-ray mirrors of the highest figure quality and micro-roughness was proposed.
Proceedings ArticleDOI
Monocrystalline silicon and the meta-shell approach to building x-ray astronomical optics
William W. Zhang,Kim D. Allgood,Michael P. Biskach,Kai-Wing Chan,Kai-Wing Chan,Michal Hlinka,John D. Kearney,James R. Mazzarella,Ryan S. McClelland,Ai Numata,L. Olsen,Raul E. Riveros,Raul E. Riveros,Timo T. Saha,Peter M. Solly +14 more
TL;DR: A technology development program whose objective is to meet this three-fold requirement of making astronomical X-ray optics: angular resolution, photon-collecting area, and production cost, based on precision polishing of monocrystalline silicon for making a large number of mirror segments and on the metashell approach to integrate them into a mirror assembly.
