Abstract

This article explores the signal produced by a silicon photomultiplier (SiPM) coupled to a LYSO scintillator in gamma spectroscopy using time and frequency-domain measurements with an oscilloscop. Analyses were performed to address the influence of coaxial cables and oscilloscope probes in the measurements. Limitations of the oscilloscopes bandwidth on the extracted pulses were studied, as well as investigation of the effect of the ambient disturbances, using the two types of cable connections. The analytic Fourier transform of the pulse is analyzed, to indentify the parameters correlating both time and frequency domain. Since there are no further additional amplifiers or signal conditioning stages after the sensor, the results represent the unfiltered signal shape collected by the oscilloscope input impedance. Conclusions are presented as guidelines and design trade-offs concerning the instrumentation and pre-amplifier design.

示波器连接和带宽对从耦合到LYSO闪烁体的SiPM信号形成的影响

本文利用示波器进行时域和频域测量，探讨了由硅光电倍增管（SiPM）耦合到LYSO闪烁体在伽马能谱中产生的信号。分析了同轴电缆和示波器探头在测量中的影响。采用两种电缆连接方式，研究了示波器带宽对提取脉冲的限制，以及环境干扰的影响。对脉冲的傅里叶解析变换进行分析，以识别时域和频域相关参数。由于在传感器之后没有进一步的附加放大器或信号调理级，因此结果表示由示波器输入阻抗收集的未滤波信号形状。结论提出了指导方针和设计权衡有关仪器和前置放大器的设计。
