闪烁探测器(计数器、量热计等)目前被广泛使用，并将在未来的新加速器实验中使用。在这种探测器中，通常使用光电倍增管(PM)来探测光。在这种类型的检测器中，不仅存在不同PM之间的特征参数的内在扩散，而且给定PM的参数也存在一定的时间相关性因此，基于PM的光谱通道的校准和监测系统是使用闪烁探测器的实验装置的重要组成部分。对绝对校准特别感兴趣，即根据从光电阴极发射的光电子数来测量闪烁体中释放的能量。通常，使用闪烁光的探测器的性能由这一比率来确定，即以每GeV的光电子数为单位。
Scintillation detectors (counters, calorimeters etc.) are presently extensively used and will be used in future experiments at new accelerators. Usually in such detectors photomultiplier tubes (PM) are used for the detection of light. In detectors of this type there exists not only an intrinsic spread in characteristic parameters among different PMs, but also some time dependence of parameters of a given PM. Therefore a system of calibration and monitoring of the PM based spectrometric channels is an important part of the experimental setups employing scintillation detectors. Particular interest is paid to the absolute calibration, ie to the measurement of the energy released in the scintillators in terms of the number of photoelectrons emitted from the photocathode. Usually the performances of detectors using scintillation light are qualified by this ratio, ie in units of photoelectrons per GeV.
