Anode (top) and the cathode (bottom) layouts of the CZT drift strip detectors. The anode strips (0.4 mm pitch; 0.25 mm gap) are orthogonal to the cathode strips (2 mm pitch; 0.1 mm gap). The anode strips are organized into collecting strips (1.6 mm pitch) and drift strips (0.4 mm pitch) which are negatively biased to optimize electron charge collection. |
