摘要
This paper presents some studies performed with a state of the art large volume, 1.5cm diameter x 1.0cm thick, cylindrical CdZnTe coplanar detector with a new anode pattern design in the line of units previously reported. The absolute efficiency of the detector for different interaction depths is quantified. The detector's ideal response is simulated with a Monte Carlo code and compared with experimental results. Some conclusions regarding interaction depth profiles, detector efficiency, the new anode pattern design and device quality are reported. These are further compared with the behavior of previous coplanar units. (c) 2004 Elsevier B.V. All rights reserved.
