Application of cold-neutron prompt gamma activation analysis at the University of Texas reactor

A cold-neutron prompt gamma activation analysis (PGAA) system is operational at the University of Texas (UT) 1 MW TRIGA research reactor. A 6 m long curved neutron guide followed by an 80 cm long converging (focusing) neutron guide transports cold neutrons from the Texas Cold Neutron Source to the PGAA chamber. The UT-PGAA system will be used to determine hydrogen and boron in semiconductor materials, gadolinium in neutron capture therapy samples, and multielementals in environmental and industrial samples.
