摘要：

The quantum electrodynamics belongs to the best tested and established theories in modern physics. However, the evaluation of high order processes, as necessary in the presence of large electric fields, is still demanding. Of particular interest in this field is the Lamb shift of highly charged, hydrogen-like ions, as the theoretically claimed error bars start to be smaller than the experimental ones. We recently started to develop a 1 x 8 detector array for high resolution x-ray spectroscopy of hydrogen-like Uranium at the GSI/FAIR. The detectors are designed to have an energy resolution below 30 eV in the relevant energy range up to 100 keV. We discuss the considerations that lead to our present detector design, as well as the present micro-fabrication techniques.
