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 in 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 (HEW) 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 a nickel electroforming replica process. The paper presents a status report of the qualification model of the x-ray optics.
