摘要
我们描述了 Suzaku 卫星上硬 X 射线探测器（HXD）的轨道性能与标定。其基本性能，包括 10-600 keV 的宽能带、40 keV 时约 4 keV（FWHM）能量分辨率和 511 keV 时约 11% 能量分辨率，以及高背景抑制效率，均通过大量轨道标定得到确认。PIN-Si 二极管的长期增益在半年内保持在 1% 以内，而荧光体的增益下降 5-20%。HXD 的残余非 X 射线背景在 15-70 keV 和 150-500 keV 能段内，为过去非成像硬 X 射线仪器中最低。我们提供了 HXD 能量响应、角响应、时钟精度以及相对于 X 射线 CCD 相机的相对标定，使用多个 Crab 星云观测实现。
