High energy X-ray telescope (HE) is one of the three instruments of Insight-HXMT (Hard X-ray Modulation Telescope) payload. The HE detector (HED) array is composed of 18 actively NaI(Tl)/CsI(Na) phoswich scintillators with a total geometric area of $\sim 5100{\text{cm}}^2$ and cover the energy range 20∼250 keV. In this paper we describe the on-ground detector-level calibration campaigns and present the principal instrument properties of HEDs.

Insight -HXMT的HE探测器的地面校准和特性

高能X射线望远镜（HE）是Insight-HXMT（硬X射线调制望远镜）有效载荷的三种仪器之一。HE检测器（HED）阵列由18个有源NaI（Tl）/ CsI（Na）磷光闪烁体组成，总几何面积为$〜5100{\text{厘米}}^2$并覆盖20至250 keV的能量范围。在本文中，我们描述了地面探测器级校准活动，并介绍了HED的主要仪器特性。
