International Workshop on Fission Product Yields
Sep. 30 - Oct. 4, 2019 Santa Fe, New Mexico, USA
Contact the organizersSep. 30 - Oct. 4, 2019 Santa Fe, New Mexico, USA
Contact the organizersWe are organizing a workshop on fission product yields (FPY) with a particular focus on measurement, theory, evaluation, and applications. This will be a 4-day (9/30 - 10/3) open workshop in Santa Fe, followed by a one-day (10/4) closed session in Los Alamos. Detailed information including the exact locations will be announced in the second circular.
In 2010, M.B. Chadwick and T. Kawano organized a small workshop on the same topics in Santa Fe, which focused primarily on improvements needed in the ENDF/B FPY evaluation, summarizing experiments and evaluations performed at different institutes in the past. The past decade has seen a significant improvement in FPY data by progress in experimental techniques, theoretical model developments, and implementation of modern data evaluation methods. Strong demands for accurate FPY data exist not only in nuclear technology applications, but also in some fundamental science areas, for instance to accurately interpret the nuclear reactor anti-neutrino anomaly and understand the synthesis of the elements in nuclear astrophysics. The broad scope and diverse nature of this effort thus motivates us to bring together an international community for the improvement of FPY data evaluation.
The meeting will bring together key scientists in the fields of experiment, theory, evaluation and statistical analysis to exchange ideas, identify areas of cooperation, and to discuss plans for future release of evaluated nuclear data libraries. Please reply to fpy2019@lanl.gov to indicate your interest in coming to the workshop. Your email will be added to a list for future correspondence.
