Session 9 - X-Ray Catalogs & Instrumentation.
Display session, Monday, January 13
Metropolitan Ballroom,
The High Energy X-Ray Timing Experiment (HEXTE) is one of three instruments carried on board the Rossi X-Ray Timing Explorer which was successfully launched on 30 December, 1995. The HEXTE consists of an array of eight phoswich scintillation counters that utilize active gain stabilization, aperture modulation and anticoincidence particle shielding to measure cosmic x-ray sources in the 15-250 keV energy range over time scales ranging from milli- seconds to months. These feature of the HEXTE allow the user to obtain precise observations of source characteristics with minimal systematic error. We discuss techniques and results of analysis of in-orbit data to calibrate the spectral, photometric, temporal and angular response of the HEXTE.
