[en]软伽马射线探测器（SGD）是ASTRO-H上的观测仪器之一，在60-600 keV范围内的灵敏度将比过去和现在的观测站高10倍。SGD采用了与ASTRO-H机载硬X射线成像仪（HXI）类似的技术。SGD通过康普顿运动学将伽马射线事件限制在狭窄的视场内，以及BGO主动屏蔽来实现低背景。在本文中，我们将介绍使用工程模型的各种试验结果，并报告飞行模型的生产和评估。（作者）
[en] The Soft Gamma-ray Detector (SGD) is one of observational instruments onboard the ASTRO-H, and will provide 10 times better sensitivity in 60-600 keV than the past and current observatories. The SGD utilizes similar technologies to the Hard X-ray Imager (HXI) onboard the ASTRO-H. The SGD achieves low background by constraining gamma-ray events within a narrow field-of-view by Compton kinematics, in addition to the BGO active shield. In this paper, we will present the results of various tests using engineering models and also report the flight model production and evaluations.(authors)
