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.
