Lithium-loaded Liquid Scintillator Production for the PROSPECT experiment



Hans Pieter Mumm, Denis E. Bergeron, Mark Tyra, Svetlana Nour, Jerome LaRosa


This work reports the production and characterization of lithium-loaded liquid scintillators (LiLS) for the Precision Reactor Oscillation and Spectrum Experiment (PROSPECT). Fifty-nine 90 L batches of LiLS (6Li mass fraction 0.082%0.001%) were produced and samples from all batches were characterized by measuring their optical absorbance relative to air, light yield relative to a pure liquid scintillator reference, and pulse shape discrimination capability. Fifty-seven batches passed the quality assurance criteria and were used for detector filling.
