中文摘要：

设计制作了用于EAST托卡马克装置水平窗口的基于CdTe探头的硬X射线诊断单元。经与EAST联机试验运行，结果表明，该诊断单元设计原理正确，空间分辨率精度及辐射屏蔽达到设计目标，能够满足测量20keV～200keV能量范围等离子体的硬X射线韧致辐射的要求。

英文摘要：

A new CdTe probe-based horizontal hard X-ray diagnostic unit was developed according to horizontal tangent array, with which an on-line trial run was done for the horizontal windows of the EAST or HT-7U tokamak. The results showed that the diagnostic unit is designed on a correct operating principle, and its high spatial resolution and radiation shield both attain the target the design required, ie., they are able to meet the requirements for measuring the x-ray bremsstrahlung of plasma in the energy range from 20 to 200keV.
