摘要：
Recent developments in Cd1-xZnxTe (CZT) crystal growth technology have enabled the production of large samples of detector grade material. In this paper we discuss the technical issues associated with building large volume CZT detectors (> 10 cm(3)) for use in gamma-ray spectroscopy. In particular, an analysis of the electronic noise in CZT devices and how it scales with detector size is presented, along with a discussion of methods to reduce noise in large CZT detector systems. The degradation of energy resolution caused by charge collection problems is also discussed and the use of electronic signal processing and improved device design to minimize charge collection effects are described.
