在光谱分析等领域中,光电倍增管的工作特性至关重要。因为目前使用的管子型号繁多(单美国就生产约550个),而引起这些管子工作特性改变的因素又多种多样,所以在工作中我们应对光电倍增管的工作特性予以高度重视。本文试对常见的光电倍增管工作特性作一简要叙述,供大家参考。一、光谱特性光电倍增管的光谱特性主要由阴极材料、窗口材料决定,同时也受温度,磁场和时间的影响,甚至和入射辐射照射的光电阴极的部位也有关。表1给出了部分美国S系列光阴极材料和窗口材料。图1给出了部分S系列光阴极的光谱响应曲线,图2给出了部分非S系列的
In the field of spectroscopy, the operating characteristics of photomultiplier tubes are of crucial importance. Because of the large number of tubes currently in use (about 550 in the United States alone) and the variability of the operating characteristics of these tubes, there is a great deal of importance in working with the operating characteristics of the photomultiplier tubes. This paper attempts to common operating characteristics of photomultiplier tube for a brief description, for your reference. First, the spectral characteristics of the photomultiplier tube spectral characteristics mainly by the cathode material, the window material, but also by the temperature, magnetic field and time, and even the incident radiation exposure of the cathode part of the photocathode. Table 1 shows some of the United States S Series photocathode materials and window materials. Figure 1 shows the spectral response curve of some S series photocathodes. Figure 2 shows the spectral responses of some S-series photocathodes
