Welcome to the Astrosat SXT at TIFR

The Soft X-Ray Telescope (SXT) on Astrosat employs focussing optics and a deep depletion CCD camera at the focal plane to perform X-ray imaging in 0.3-8.0 keV band. The SXT optics consists of 40 concentric shells of gold-coated conical foil mirrors in an approximate Wolter-I configuration. The focal plane CCD Camera is very similar to that flown on SWIFT XRT. The CCD is operated at a temperature of about -82 deg.C by thermoelectric cooling. Click here to see LOG OF OBSERVATIONS: POC
