The time response of the crystal, essential for several nuclear physics applications, has also been studied, yielding a time resolution of 260(1) ps for a single detector for 1173–1333 keV

2个“×2”CeBr3闪烁体探测器的表征

利用能量为81 ~ 4440 keV的γ射线源，研究了一个圆柱形CeBr3探测器，2“×2”晶体耦合到一个光电倍增管（PMT） Hamamatsu R13089-100。并将探测器的实测能量响应与Geant4仿真结果进行了比较。晶体的时间响应，对几个核物理应用至关重要，也进行了研究，为1173-1333 keV γ射线级联的单个探测器提供了260(1)ps的时间分辨率。此外，还确定了探测器的固有效率，并将其与模拟结果进行了比较，这是该晶体尺寸首次报道的结果。

期刊介绍： Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section. Theoretical as well as experimental papers are accepted.
