Abstract
The characteristics and performance for two of the latest coplanar grid CdZnTe detectors, which use the third-generation coplanar grid design, will be discussed. These detectors, with dimensions of 1.5x1.5x0.9 cm3 and 1.5x1.5x0.95 cm3, were fabricated by Baltic Scientific Instruments, Ltd., using crystals from Yinnel Tech, Inc. The high electron mobility-lifetime product measured for these crystals will lead to improved charge collection efficiency and better energy resolution. The spectroscopic performance obtained from the detectors, employing various methods such as depth sensing, radial sensing, and relative gain compensation, will be reported. Results from these measurements will give us insight into the material properties as well as the charge induction uniformity of the detector.
