The High Energy X-ray Timing Experiment (HEXTE)Mission: Rossi X-Ray Timing Explorer (RXTE).
The HEXTE consisted of two clusters each containing four `phoswich scintillation detectors. Each cluster could ``rock'' (beamswitch) along mutually orthogonal directions to provide background measurements 1.5 or 3.0 degrees away from the source every 16 to 128 s. Automatic gain control was provided by using a 241Am radioactive source mounted in each detector's field of view. The HEXTE's basic properties are:
The HEXTE was designed and built by the Center for Astrophysics & Space Sciences (CASS) at the University of California, San Diego. For more information on the in-flight performance of HEXTE, see the article by Rothschild et al. (1998, ApJ, 496, 538 and the CASS HEXTE website.
The HEXTE principal investigator is Dr. Richard E. Rothschild.
