The Broad Band X-ray Telescope (BBXRT) was flown on the space
shuttle Columbia (STS-35) as part of the ASTRO-1 payload.
It was designed and built at the Astrophysics Science Division at NASA/GSFC.
BBXRT was the first focusing X-ray telescope operating over
a broad energy range 0.3-12 keV with a moderate
energy resolution (90 eV at 1 keV and 150eV at 6 keV).
Mission Characteristics
Lifetime: December 2 1990 - December 11 1990
Energy Range: 0.3 - 12 keV
Payload:
Two Co-Aligned Telescopes each with a segmented Si(Li) solid state
spectrometer (detector A and B) composite of five pixels.
Total FOV 17.4 ´ diameter, Central pixel FOV 4 ´ diameter
Total area 765 cm2 at 1.5 keV, and 300 cm2 at 7 keV
Science Highlight:
- Resolved iron K line in the binaries Cen X-3 and Cyg X-2
- Detect evidence of line broadening in NGC 4151
- Study of cooling flow in clusters
