Direct measurement of the total quantum counting efficiency of the RCA C31000E/F shows that it is about 25 +/- 22% lower than the photocathode quantum efficiency in optimized commercial base units. Measurements with an EMI 9558 give similar results and with an Amperex 56TVP give similar although more erratic results due to its higher sensitivity to magnetic fields. The measurement techniques and conditions are described in detail. Diagnostic studies such as the question of dependence of counting efficiency on signal or background count rate are also presented.
对RCA C31000E/F的总量子计数效率的直接测量表明，在优化的商用基本单元中，它比光电阴极量子效率低约25±22%。使用EMI 9558进行的测量给出了类似的结果，而使用Amperex 56TVP进行的测量虽然结果更不稳定，但也给出了类似的结果，这是因为它对磁场的敏感度更高。详细描述了测量技术和条件。还介绍了诸如计数效率对信号或背景计数率的依赖性等诊断研究。
