Measurement System of Decay Time for Liquid Scintillator

Article Preview

Abstract:

The fluorescence lifetime of the molecular excited states in the liquid scintillator determines the pulse shape of the events in a detector. The fluorescence decay times of the mixtures could be measured by UV light excitation, or via ionizing particles. Both of the setups are based on the time-correlated single photon technique. In this paper we described a setup in detail for testing the fluorescence lifetime under ionizing particle to render the relatively weak neutron or ion signals detectable. In addition, we presented the time resolution of system for the setup.
