| Abstract: | The Broad-Band X-Ray Telescope (BBXRT) has been designed to perform high sensitivity, moderate resolution spectrophototnetry of X-ray sources in the 0.3–12 keV band from the Shuttle. It consists of a coaligned pair of high throughput, conical X-ray imaging mirrors, with a cryogenically-cooled, multiple element, Si(Li) spectrometer at the focus of each. On axis, BBXRT will have an effective area of 580 cm2 at 2 keV and 250 cm2 at 7 keV, and a spectral resolution of 110 eV at 2 keV and 150 eV at 7 keV. A 104 s observation with BBXRT will allow a determination of the continuum spectral shape for sources near the Einstein deep survey limit. |
