We have thoroughly investigated the design and construction of a neutron focusing system for use with the Texas Cold Neutron Source (TCNS). The focusing system will be located at the end of the TCNS curved neutron guide to increase the neutron flux for neutron capture experiments that benefit from the low background expected at the end of the curved guide. An example of such an experiment, and one we plan to set up, is prompt gamma activation analysis, a nondestructive nuclear analytical technique based on spectroscopy of neutron capture gamma rays. After examining several methods for neutron focusing, we decided to design a converging neutron guide for use as a focusing system. Different multielement converging guides were designed and analyzed. Each consisted of a number of truncated rectangular cone sections. From the results of our study, we will select one of these guides for construction. Since the cost is expected to be quite high, the decision will be based on a cost-benefit argument.
