Study of output spectrum and optimization of the composition of toluene-based liquid scintillator
August 30, 2022
Liquid scintillator is widely used as a medium for the detection of charged particles for numerous applications in science, medicine, and in other areas. The composition of scintillator affects not only its performance, but also the overall cost. The scintillator light output spectrum also affects a choice of detectors that can be used in conjuncture with a particular scintillator formula. Optimization of this composition provides the ability to design particle detectors with a certain light yield and emission spectra of the detection medium, or to maximize the light yield while optimizing the expenses. This work presents the component optimization for the toluene-based liquid scintillator that uses PPO as a fluor and POPOP as a secondary shifter. The light yield vs concentration and the changes in the output spectra will be discussed. Plans for future work include the light attenuation measurements.
