The X-Ray Imaging Telescopes on EXOSAT

Space Science Reviews, 1981
The instrument configuration and performance characteristics of the X-ray imaging telescopes on EXOSAT are described. The instrument comprises two fully independent Wolter I imaging telescopes. Each telescope can be used in either of two principal modes: (i) an imaging mode with either a position sensitive proportional counter or a channel multiplier ...

Operation of the x-ray telescope eROSITA

SPIE Proceedings, 2010
The X-ray telescope eROSITA is the core instrument besides the Russian ART-XC on the Russian Spektrum-Roentgen- Gamma satellite which will be launched in 2012 to an orbit around the L2 point of the Earth-Sun-system. During both survey and pointing phase the solar panels and the antenna constrain the possible mission scenario.

Wolter-Schwarzschild Telescopes for X-Ray Astronomy

Applied Optics, 1973
The resolution of a Wolter-Schwarzschild telescope is intrinsically superior to the resolution of the corresponding paraboloid-hyperboloid telescope. The improvement is important for high resolution and wide field telescope designs having grazing angles larger than about 1.5 degrees .

Observation of a Solar Flare at the Limb with the Yohkoh Soft X-Ray Telescope

Nippon Tenmon Gakkai obun kenkyu hokoku, 1992
A long-enduring soft X-ray flare at the solar limb was well observed by the Soft X-ray Telescope aboard the Yohkoh spacecraft from its pre-flare stage through the post-flare phase.

The Swift X-Ray Telescope

AIP Conference Proceedings, 2003
The Swift Gamma‐Ray Burst Explorer is designed to make prompt multiwavelength observations of Gamma‐Ray Bursts (GRBs) and their afterglows. The X‐ray Telescope (XRT) provides key capabilities that permit Swift to determine GRB positions with several arcsecond accuracy within 100 seconds of the burst onset.

Novel X-ray telescopes for wide-field X-ray monitoring

Il Nuovo Cimento C, 2005
We report on fully innovative very wide-field of view X-ray telescopes with high sensitivity as well as large field of view. The prototypes are very promising, allowing the proposals for space projects with very wide-field Lobstereye X-ray optics to be considered.

Grazing Incidence X-Ray Telescopes

1969
This paper reviews some of the work related to X-ray imaging which has been done at our laboratory over the past several years. Our interest has been to develop high resolution telescopes for studying X-ray emission from the sun and from other celestial X-ray sources.
