Benchmark Experiment of Neutron Resonance Scattering Models in Monte Carlo Codes
نویسندگان
چکیده
Experimental measurements of elastic neutron scattering from U resonances were used to benchmark neutron scattering models in Monte Carlo transport codes. It was found that the implementation of the free gas model to determine the scattered neutron energy and angle in popular Monte Carlo codes is inaccurate. Differences up to a factor of two in the energy dependent angular distribution were observed. The experimental data presented here provides validation of an improved free gas model that was developed by one of the authors (Dagan). This improved free gas model allows accurate simulation of the experimental results

High Energy Neutron Scattering Benchmark of Monte Carlo Computations
Neutron scattering measurements are made using an array of proton recoil detectors surrounding a scattering sample, which is struck by a beam of neutrons. Detector signals are analyzed using a state of the art digital data acquisition system, and these measurements are compared with the expected detector response based on Monte Carlo simulation of the scattering experiment using existing nuclea...

Neutron is one of the products of the interaction of high energy protons with light nuclei. Using computational Monte Carlo codes, it is possible to calculate and predict the neutron spectrum, neutron flux, and doses by simulating the system. But the use of different hadronic models in this process can influence the results of these calculations. In this research, the response of the four hadro...

متن کاملPerformance Gain with Low-Enriched Fuel and Optimized Use of Neutrons
The most challenging type of reactors to convert to low-enriched fuel are high-flux research reactors, which, along with some spallation sources, are the most important neutron sources for modern neutron scattering experiments. Advanced Monte-Carlo computer codes are now available that make it possible to track neutrons from the reactor core, through neutron guides, to instruments and detectors...
