SUMMARY

In this work, solidified organic scintillator detection systems accurately performed PSD in order to separate neutrons and gamma rays. MATLAB software was implemented to separate the signals with an applied energy filter. Measurements of Co-60, Na-22, Cs-137, and Thorium were conducted to confirm gamma ray detection before proceeding to neutron detection. The performances of the systems were verified through measurements of unmoderated PuBe, lead shielded PuBe, and borated polyethylene PuBe. The goal of this thesis work was to produce a working neutron detector usable in a field environment from LS mixtures. The goal was achieved by the small and large EJ 309 solidified detectors. These detectors can be placed into a mixed radiation field and detect high energy neutrons
