Beta-delayed neutron spectroscopy using trapped radioactive ions
These measurements will improve the accuracy for delayed-neutron data for safety and accident analysis for fast reactors and other novel fuel cycle applications. Currently, much of the delayed-neutron data used in calculations has large uncertainties and in some cases results disagree by factors of 2-3. A comprehensive program of beta-delayed neutron spectroscopy measurements will be carried out at Argonne National Laboratory using neutron-rich fission-fragment beams from the Californium Rare Ion Breeder Upgrade (CARIBU). Sophisticated ion-trapping techniques and modern radiation detection systems will be employed to realize these measurements with high efficiency and energy resolutions approaching 1%.
