Paper Abstract

The Joint European X-Ray Telescope, JET-X, is one of the core instruments of the scientific payload of the Russian SPECTRUM-X astrophysics mission. JET-X is designed to study the emission from x-ray sources in the band of 0.3 - 10 KeV, particularly to meet primary scientific goals is cosmology and extragalactic astronomy. JET-X consists of two identical, coaligned x-ray telescopes, each with a spatial resolution of 30 arcsecond Half Energy Width or better. Focal plane imaging is provided by cooled x-ray sensitive CCD detectors which will combine high spatial resolution with good spectral resolution, with particular emphasis on high sensitivity and spectral resolution around the 7 KeV Fe-line complex. Each telescope is composed of a nested array of 12 mirrors with an aperture of 0.3 m and focal length of 3.5 m; the total effective area is 360 cm2 at 1.5 KeV and 140 cm2 at 8 KeV. The mirror shells have a Wolter I geometry and are manufactured by an electroforming replica process. The paper presents a status report concerning the development of the X-ray optics.
