The ProtoEXIST program was conceived for the development of a scalable detector plane architecture utilizing pixilated CdZnTe (CZT) detectors for eventual deployment in a large scale (1-4 m2 active area) coded aperture X-ray telescope for use as a wide field ( 90° × 70° FOV) all sky monitor and survey instrument for the 5 up to 600 keV energy band. The first phase of the program recently concluded with the successful 6 hour high altitude (39 km) flight of ProtoEXIST1, which utilized a closely tiled 8 × 8 array of 20 mm × 20 mm, 5 mm thick Redlen CZT crystals each bonded to a RadNET asic via an interposer board. Each individual CZT crystal utilized a 8 × 8 pixilated anode for the creation of a position sensitive detector with 2.5 mm spatial resolution. Development of ProtoEXIST2, the second advanced CZT detector plane in this series, is currently under way. ProtoEXIST2 will be composed of a closely tiled 8 × 8 array of 20 mm × 20 mm, 5 mm thick Redlen CZT crystals, similar to ProtoEXIST1, but will now utilize the Nu-ASIC which accommodates the direct bonding of CZT detectors with a 32 × 32 pixilated anode with a 604.8 μm pixel pitch. Characterization and performance of the ProtoEXIST2 detectors is discussed as well as current progress in the integration of the ProtoEXIST2 detector plane.
