Swift Instrumentation


Swift's three scientific instruments work together to learn as much as possible about gamma-ray bursts. The Burst Alert telescope (BAT) is the first instrument to detect gamma-rays in the quarter of the sky at which it is pointed. Then the satellite is reoriented using data from BAT so that XRT and UVOT, which have a much smaller field of view, can be pointed at the GRB. With this information, ground-based telescopes can be pointed directly at the source to gather more data about the GRB.
