| 摘 要： | 对同轴Ge(Li)探测器进行不同表面处理,采用~(241)Am59.6 keV准直γ束扫描来研究探测器的表面性能。从测得的探测器表面各点脉冲谱及光电峰相对效率,说明在探测器表面存在着强弱不同的N或P型表面沟道。当探测器表面存在N型沟道时,可得到比较好的探测器特性。

| Abstract: | In order to study the effect due to various surface treatments, the de tectorsare scanned from the N to P contact with a collimated beam (241Am. 59.6 keV). The measured pulse height spectrum and the full energy peak efficiency show that there exist N or P type surface channels strong or weak, If there is N type surface channel on the surface, a reletively good performance of the detector will be obtained. |
