Proceedings ArticleDOI
Active x-ray optics for the next generation of x-ray telescopes
Carolyn Atkins,Hongchang Wang,Peter Doel,David J. Brooks,Samantha Thompson,Charlotte Feldman,Richard Willingale,Tim W. Button,Daniel San-Martín,Dou Zhang,Ady James,Craig Theobald,Graham Willis,Andy D. Smith +13 more
TL;DR: The Smart X-ray Optics (SXO) project is a UK-based consortium looking at the application of active/adaptive optics to both large and small scale devices, intended for astronomical and medical purposes respectively as mentioned in this paper.
Journal ArticleDOI
Development of piezoelectric actuators for active X-ray optics
Dou Zhang,D. Rodriguez-Sanmartin,Tim W. Button,Carolyn Atkins,David J. Brooks,Peter Doel,Camelia Dunare,Charlotte Feldman,Ady James,Alan Michette,William Parkes,Slawka J. Pfauntsch,Shahin Sahraei,Tom Stevenson,Hongchang Wang,Richard Willingale +15 more
TL;DR: In this paper, two new prototype adaptive X-ray optical systems are under development with the aim of approaching the fundamental diffraction limit, one of which is micro-structured optical arrays (MOAs) involving two or four piezoelectric strips bonded to a silicon wafer to produce a micro-focused Xray source for biological applications, and which uses grazing incidence reflection through consecutive aligned arrays of channels obtained using deep silicon etching.
Proceedings ArticleDOI
Development of thin-shell adaptive optics for high angular resolution x-ray telescopes
Charlotte Feldman,Richard Willingale,Carolyn Atkins,Hongchang Wang,Peter Doel,David J. Brooks,Samantha Thompson,Tim W. Button,Dou Zhang,Daniel San-Martín,Ady James,Craig Theobald +11 more
TL;DR: The Smart X-ray Optics project is a UK-based consortium of eight institutions investigating the application of active/adaptive Xray optics for both large and small scale as discussed by the authors, which includes the modelling and testing of a large scale optic, suitable for an Xray telescope.
Proceedings ArticleDOI
Advances in active X-ray telescope technologies
Carolyn Atkins,Peter Doel,David J. Brooks,Samantha Thompson,Charlotte Feldman,Richard Willingale,Tim W. Button,Daniel San-Martín,Dou Zhang,Ady James,Craig Theobald,Andrew Smith,Hongchang Wang +12 more
TL;DR: In this article, the authors present a critical analysis of the first prototype system, discussing metrology of the mandrel, the nickel replicated ellipsoidal optics and the prototype.
Proceedings ArticleDOI
Future high-resolution x-ray telescope technologies: prototype fabrication methods and finite element analysis
