In-flight performance of the high energy X-ray timing experiment on the ROSSI X-ray Timing Explorer

摘要

The High Energy X-ray Timing Experiment(HEXTE) is one of three scientific instruments aboard the Rossi X-Ray Timing Explorer(RXTE), which was launched on 1995 December 30. RXTE performs timing and spectral studied of bright X-ray sources to determine the physical parameters of these systems. The HEXTE consists of two independent clusters of detectors, each cluster containing four NaI(TI)/CsI(Na) phoswich scintillation counters sharing a common 1°FWHM field of view.
