Organic Scintillator Modeling Efforts in MCNP6 and DRiFT for the NEUANCE/DANCE Detector Array

The NEUtron detector Array at DANCE (NEUANCE) is a new stilbene detector array that is currently under development at Los Alamos National Laboratory. It is designed to fit inside the Detector for Advanced Neutron Capture Experiments (DANCE), a very high-efficiency gamma-ray calorimeter used to measure prompt fission and capture gamma rays. MCNP simulations were performed to determine the optimal Gaussian energy broadening parameters to attain an accurate stilbene gamma-ray detector response function, and compare simulation results to measurements already taken at NEUANCE. Work is also currently being done to add stilbene processing capabilities to the Detector Response Function Toolkit for MCNP (DRiFT).
