Supermirror hard-x-ray telescope

Applied Optics, 1998
The practical use of a grazing x-ray telescope is demonstrated for hard-x-ray imaging as hard as 40 keV by means of a depth-graded d-spacing multilayer, a so-called supermirror. Platinum-carbon multilayers of 26 layer pairs in three blocks with a different periodic length d of 3-5 nm were designed to enhance the reflectivity in the energy range from 24

Wide field x-ray telescope mission

SPIE Proceedings, 2008
The Wide Field X-Ray Telescope (WFXT) will carry out an unprecedented X-ray survey of galaxy clusters and groups, AGNs and QSOs, and galaxies. WFXT is a medium-class strategic mission that will address key questions in both Cosmic Origins and Physics of the Cosmos.

Monochromatic X-ray source for calibrating X-ray telescopes

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2000
Abstract A quasi-monochromatic X-ray source for calibrating X-ray space telescopes was developed, manufactured and tested. The source consists of a powerful X-ray tube of an open type with changeable anode targets and a regulated double-crystal monochromator.

Development of x-ray mirrors for x-ray telescopes

SPIE Proceedings, 2005
We have been developing X-ray mirrors for X-ray telescope using a ion-beam sputtering system. X-rays can be reflected by two processes, one is total reflection, and another is Bragg reflection. Total reflection is used for previous telescope below 10 keV. Its reflectivity determined by the optical constant. We suggests composite-layer mirror for soft X-

X-ray telescopes

Reports on Progress in Physics, 1985
This review summarises the present knowledge about X-ray reflection from real mirrors, with particular emphasis on X-ray scattering. The mirror configurations for a telescope are presented and their imaging capabilities are discussed. The fabrication techniques and the supporting metrology methods used for the manufacture of highly aspherical telescope

Hybrid X-Ray Telescope Systems

SPIE Proceedings, 1986
It has been known for some time that glancing incidence X-ray optics have sharply peaked point response functions. The spatial resolution of Wolter X-ray telescope systems is frequently limited by the performance characteristics of the X-ray detector rather than by the optics, even when high resolution detectors such as photographic emulsions are used.
