Correlations of Prompt Fission Radiation in Measurements with DANCE and NEUANCE

The field of nuclear physics is a vast discipline, with many discoveries made, and many more opportunities for research and development. In particular, the field of nuclear data evaluation is ripe with challenging topics to tackle. Nuclear data libraries such as ENDF, ENDL, JENDL are constantly being updated and improved upon as research groups around the world collect and evaluate nuclear data. Despite the large effort, many of these libraries are still lacking information, and are often limited to basic quantities for only the most common isotopes. In the field of fission, a notable contributor to this issue is the lack of detector systems able to measure such complex quantities with adequate precision and efficiency. The Detector for Advanced Neutron Capture Experiments (DANCE) is a 4π detector array that consists of up to 160 BaF₂ scintillation detectors; its design allows for high efficiency detection of prompt gamma rays following a neutron capture. The most recent release of Monte Carlo N-Particle code (MCNP®) implements fission event generators Cascading Gamma-ray Multiplicity code for Fission (CGMF) and Fission Reaction Event Yield Algorithm (FREYA) that can be paired with existing MCNP tools, such as PTRAC, to simulate and analyze fission events on an event-by-event basis. With the successful creation of a model of DANCE in MCNP, the following work will present initial analysis of fission simulations ran in MCNP using CGMF and PTRAC in the DANCE array.
