Enhancing neutron spectral results based on the combination of genetic algorithm and activation method
- 87 Downloads
The generated neutron spectrum from KIRAMS MC-50 cyclotron has been adjusted and enhanced by the combination of the genetic algorithm (GA) and activation foil methods. The activation rates were derived from the measurements of Shieldwerx activation foil using the ORTEC HPGe spectroscopy system and applying the GA method to return the adjusted spectral information. It is worth mentioning here that the result, which was successfully validated with the unfolding spectrum from STAY’SL PNNL code, is significant as it will be a referenced neutron spectrum for the experiments of the MC-50 cyclotron.
