本文报道了高分辨率N型HPGe同轴探测器的研究结果。探索了探测器外侧大面积P+N结的离子注入条件与其反向V—I_L特性的关系。实验证明:在一定的离子能量和束流条件下,较高注入剂量的探测器具有较理想的V—I_L特性——高反偏压和低漏电流。探测器已被用于煤田中子俘获γ能谱测井和油田放射性刻度井测试仪。
This paper reports the results of a high-resolution N-type HPGe coaxial detector. The relationship between the ion implantation conditions and the reverse V-I_L characteristics of large area P + N junction outside the detector was explored. Experiments show that under certain ion energy and beam conditions, the higher injection dose detector has better V-I_L characteristics - high reverse bias and low leakage current. Detectors have been used in coalfield neutron capture gamma spectrometry logging and oilfield radioactivity calibration well testers.
