Implementation of autocorrelation method for investigations of the scintillator decay time and space correlation of radiation

A new method to determine scintillator decay time and space correlation of radiation is described. The method is based on an autocorrelation delayed-coincidence time spectrometer and it has been applied to measure the decay time of inorganic and organic scintillators in a range from tens of nanoseconds to a few microseconds. Results with NAFTALEN and CsI(Tl) show decay times of τ=75.0(8) ns and 998(15) ns, respectively.
