Abstract
In a method for determining a gain factor of a photomultiplier, a radiation source arrangement emits gamma quanta that a scintillation arrangement absorbs and thereby emits photons. The photomultiplier is optically coupled to the scintillation arrangement and emits a signal dependent on the incident photons. The gamma quanta emitted by the radiation source arrangement are collimated onto a measuring location arranged on the scintillation arrangement. A signal amplitude spectrum of the signal is registered using the photomultiplier. Parameters of the signal amplitude spectrum are determined. The gain factor that describes the dependency between the incident photons and the signal is determined on the basis of these parameters.
