Abstract:
The response function of the detectors is strongly dependent on the atomic number. If the photoelectric cross-section is large in detectors with high atomic numbers, this phenomenon is practically irrelevant in plastic or liquid scintillators and the dominant response is the continuous Compton spectra.
We propose a simple method for energy calibration using the Compton edge of various standard gamma sources. This method was tested for two different plastic scintillators (EJ 440 and EJ 200) and liquid scintillator (EJ 309), all produced by Eljen Technology/Scionix.
