Abstract

In order to estimate the number of scintillation photons emitted in NaI(Tl) and plastic scintillators by gamma-rays, the number of photoelectrons from the photomultiplier photocathode was absolutely measured with several combinations of photomultipliers and scintillators. The photomultipliers were used as a vacuum photodiode. The number of scintillation photons was estimated by using the effective quantum efficiency and the collection efficiency of photons by the photocathode.<>

伽玛射线在NaI(Tl)和塑料闪烁体中发射的闪烁光子数

为了估计伽马射线在NaI(Tl)和塑料闪烁体中发射的闪烁光子的数量，用几种光电倍增管和闪烁管的组合对光电倍增管光电阴极的光电子数量进行了绝对测量。光电倍增管用作真空光电二极管。利用光电阴极的有效量子效率和光子收集效率估算了闪烁光子的数量。
