摘　　要：Si(Li)X射线探测器在核技术应用领域十分有用,我们制成的系列化的高分辨率Si(Li)X射线探测器,器件最大灵敏面积为200mm^2,对5.9keV最好能量分辨率(FWHM)为216eV,能量分辨率的平均值是223eV,另一只28mm^2Si(Li)探测器的最好能量分辨率为139.6eV。Si(Li) X-ray detectors are available today in the field of nuclear techniques. At pre-sent we have made a series of Si (Li) X-ray detectors with high resolution. The processing technology and performance of the detectors are described. The largest active area of the devices is 200 mm2 with the best resolution (FWHM) of 216 eV and an average resolution of 223 eV for 5.9 keV. The best resolution for 28mm2 Si(Li) detector is 139.6eV.
