Abstract

We report on the design and construction of a tiled Cadmium Zinc Telluride (CZT) detector array, suitable for use as an astronomical coded aperture imager. Four detector modules, each with 4 × 4 × 0.5 cm of CZT, readout by two 128 channel XA type ASICs, have been built and incorporated into a detector focal plane array. A passive shield/collimator surrounded by plastic scintillator encloses the detector on five sides and provides a 40 degree field of view. In this paper, we present our performance goals and some preliminary calibration results.
