室温CZT探测器能量分辨率的提高

Energy resolution improvement in room-temperature CZT detectors

Y. Ramachers, D. Y. Stewart

摘要:

我们提出了提高单通道室温碲锌镉(CZT)探测器能量分辨率的方法。一个新的MEMS设计可以从晶体中获取实际的瞬态电流,直接的数据分析方法为我们的测试探测器提供了前所未有的能量分辨率。这些包括标准的eV-CAPTURE Plus晶体和由低级共面栅格探测器内部创建的1 cm立方体Frisch collar晶体。在662 keV处,我们的项圈探测器的能量分辨率为1.9%,eV晶体的能量分辨率为0.8%。后者与像素探测器的最佳现有能量分辨率结果相比是有利的。

英文摘要:

We present methods to improve the energy resolution of single-channel, room-temperature Cadmium-Zinc-Telluride (CZT) detectors. A new preamplifier design enables the acquisition of the actual transient current from the crystals and straightforward data analysis methods yield unprecedented energy resolution for our test-detectors. These consist of an eV-CAPture Plus crystal as standard and 1 cm cube Frisch collar crystals created in-house from low-grade coplanar grid detectors. Energy resolutions of 1.9% for our collar detectors and 0.8% for the eV crystal at 662 keV were obtained. The latter compares favourably to the best existing energy resolution results from pixel detectors.
