Experiments to Measure Variations in the Neutron Flux Delivered by the Texas Cold Neutron Source

摘要

The University of Texas at Austin (UT) Nuclear Engineering Teaching Laboratory (UT-NETL) has been using cold neutron prompt gamma activation analysis (PGAA) to characterize carbon fiber reinforced, polymer matrix composite materials. To support quantitative determination of carbon composite constituents, efforts have been made to characterize temporal and spatial variations in the neutron flux delivered by the Texas Cold Neutron Source (TCNS).
