HAMAMATSU的H8500型64路多阳极平板型光电倍增管以其非常优越的位置分辨被广泛地应用于各种小型探测装置和大型阵列探测装置,多信号的有效、快速和最为经济的简化电子学线路读出成为多阳极光电倍增管非常重要的研究内容。基于DPC电桥简化处理多阳极光电倍增管信号,在未采用铅准直的情况下测量137Csγ源最好位置分辨(FWHM)达到了2mm左右。
HAMAMATSU’s Model H8500 64-channel, multi-anode, planar photomultiplier tube is widely used in a variety of small and large array probing devices for its superior position resolution. The efficient, fast and economical circuit simplification of multiple signals Read out as a multi-anode PMT is very important research. Based on DPC bridge simplification of multi-anode photomultiplier signal, the best position resolution (FWHM) of 137Cs γ source measured without lead collimation reached about 2mm.
