Abstract

The preliminary design for the 15 - 250 keV, 200 cm², phoswich detectors for the High Energy X-ray Timing Experiment (HEXTE) for NASA's X-ray Timing Explorer mission has been completed, and the first engineering model has been fabricated. This unit has undergone extensive environmental and performance testing, including extended vibration, thermal range, resolution, uniformity, and pulse shape, and is within specifications for all tests. Broad beam energy resolution of better than 15% at 60 keV and clear separation of NaI and CsI pulse shape peaks are seen. The design and test results will be presented.
