摘要
The present disclosure describes gain stabilization techniques for scintillation devices which do not require use of an intrinsic reference radiation source. Reference light pulses are emitted into the scintillation device to obtain a signal having a given magnitude. The magnitude of the signal is compared to the magnitude of a reference signal computed as a function of temperature and a degradation factor. A gain adjustment is computed with causes the magnitude of the signal to match the target reference magnitude. The gain adjustment is then used to adjust the system gain so that subsequent output signal amplitudes, measured when energetic photons interact in the scintillator, always correspond to the same energy.
