Improving Light Yield Measurements for Low-Yield Scintillators

Understand

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.
