X-ray timing explorer mission

摘要: The XTE will address a number of fundamental questions about the nature cosmos. large effective area (∼ 0.8m 2 total) and broad band sensitivity (2-200 keV) its three instruments make it especially valuable for timing intensity variations determination broad-band spectra from high-energy sources. For first time, studies variability ranging 1 microsecond to several years be carried out. XTE's design flexibility operations allow respond rapidly changes in X-ray sky (within hours) facilitate multifrequency observations
