SiPM耦合LYSO晶体探测器的能量分辨和时间分辨

摘要

本文采用符合测量的方法研究了SENLE公司生产的型号为MicroFC-30035-SMT的SiPM光电转换器件耦合尺寸为3×3×10 mm的LYSO晶体组成的闪烁探测器的能量分辨率和时间分辨.该探测器测得22Na放射源能量为511 keV光子的能量分辨率(FWHM)为16％,时间分辨达135 ps.%This paper studies the energy resolution and time resolution of scintillation detector produced by SENLE Company with appropriate measuring method.The detector is composed by LYSO crystal (model MicroFC-30035-SMT),and the coupling size of SiPM optical-electrical converter is 3 × 3 × 10 nmn.The measuring result of the detector is:the energy of 22 Na radioactive source is 511 keV,the energy resolution (FWHM) of 511 keV photon is 16％,and the time resolution is 135 ps.
