本文介绍了新一代复合锗探测器：Clover 探测器的特点。其开发基于使用代码 GEANT3 进行的模拟计算。对其主要特性进行了广泛的研究，包括光峰值检测效率、能量分辨率以及使用源和束内实验进行的定时。提出了一种简单的多普勒展宽校正程序来提高 Clover 探测器的束内能量分辨率。另一个重要的特性是对 γ 射线线性偏振的敏感性已经被测量。还报告了使用相关 BGO 抑制屏蔽获得的性能。所有这些结果与最初的模拟计算结果非常吻合。
This paper presents the characteristics of a new generation of composite germanium detectors: the Clover detector. Its development was based on simulation calculations performed with the code GEANT3. An extensive study of its main characteristics involving the photopeak detection efficiency, the energy resolution and the timing performed with sources and in-beam experiments have been measured. A simple Doppler broadening correction procedure is proposed to improve the in-beam energy resolution of the Clover detector. An other important property, the sensitivity to the linear polarisation of γ-rays has been measured. The performances obtained with the associated BGO suppression shield are also reported. All these results compare very well with the initial simulation calculations.
