A Comprehensive Technique for Determining the Intrinsic Light Yield of Scintillators

Precise knowledge of the intrinsic light yield of scintillating materials is important for characterizing, optimizing, and simulating scintillating detectors for radiation detection applications. We present here a comprehensive method for determining the intrinsic light yield of scintillating materials. By maintaining complete control over all aspects of photodetector response measurement, and through the use of a novel method for direct measurement of the light collection efficiency of the scintillator, we have successfully demonstrated that our technique allows for new levels of precision and understanding in the measurement of the intrinsic light yield of scintillating materials.
