The Responce Of A 4π Neutron Detector Built For K-500 Superconducting Cyclotron At Texas A&M University

Abstract

A 4π neutron detector which has a relatively high efficiency for detecting neutrons emitted in nuclear reactions has been constructed. This new 4π neutron detector has been designed to be much more flexible than the traditional fission tank used in off line measurements. The most important quantity to be determined for this detector is the response function, i.e., the efficiency as a function of the neutron energy. Monte Carlo methods are used to simulate the response of the detector. Comparisons between the theoretical and the measured efficiencies should provide the basic information about the characteristics of the detector which is to be used for in-beam studies with the new K-500 superconducting cyclotron at Texas A&M University. Further modifications and applications of the Monte Carlo simulation program are also discussed in this thesis.
