Improving light yield measurements for low-yield scintillators
Abstract
Light power spectra are introduced as a new tool for relative light yield (LY) determinations. Light event spectra have commonly been used for this purpose. Theoretical background supporting this change is provided. It is shown that the derivative of a light power spectrum can provide a reliable LY measurement at levels as low as 2% of those for high-yield liquid scintillators. In this work, applications to light evolution in the PPO+LAB system and to water-based liquid scintillators are described.
