Top: one CZT detector (10 mm × 10 mm × 2 mm) and its associated electronics board with preamp, LNA and shaper. The actual components of the LNA are on the opposite side of the board to avoid electrical interference. The thick wire is the high-voltage supply to the detector (the blue wire is a test lead). Bottom: a computer rendering of an exploded view of the detector system. The upper plate is a structural Al frame in which a 0.016 mm-thick aluminum foil will be stretched to provide light and electrical shielding to the detectors. The bottom brass piece provides structure and casing for the detectors and PCBs.
