Measurement on Light Yield of Liquid Scintillator Based on P-Xylene

Abstract:

The relative light output of liquid scintillator based on p-xylene (PX) was measured in this paper. The setup for testing on light output was clearly displayed. The results showed that the light yield increased as the addition of the second solute p-bis (o-methylatyryl)- benzene (bis-MSB). Bis-MSB moves the maxmun of fluorescence emission spectra of liquid scintillator from 365nm to 425nm, which is the most sensitive region for the PMT, so the possibility of self-absorption and the loss of light output could be reduced to some extent.
