Abstract—

Since ⁶⁰Co gamma peaks in the gamma energy spectrum were not revealed in the electronic noise by the Multi-Pixel Photon Counter (MPPC), an experimental setup was proposed to reduce the noise, and to unveil the peaks and the gamma spectrum. For this purpose, constant fraction timing discrimination method was utilized. The timing signals were coincidentally gated in the multichannel analyzer with the signals directly from the MPPC. Obtained result spectrum showed that the asserted setup was quite successful in reducing the noise components, and in obtaining the neat gamma peaks of the radioisotope through the MPPC.

通过多像素光子计数器显示 60Co 伽马峰

摘要-

由于多像素光子计数器 (MPPC) 在电子噪声中没有显示伽马能谱中的^{60 个}Co 伽马峰，因此提出了一种实验装置来降低噪声，并揭示峰值和伽马谱。为此，使用了恒定分数定时鉴别方法。定时信号在多通道分析仪中与直接来自 MPPC 的信号同时门控。获得的结果谱表明，所声称的设置在减少噪声成分方面非常成功，并且通过 MPPC 获得了放射性同位素的纯伽马峰。
