Half Monte Carlo method

Instead of running hundreds or thousands of neutronics calculations, we therefore investigate the possibility to take those many cross-section file samples and perform ‘cheap’ sensitivity perturbation calculations. This is efficiently possible with the NEA Nuclear Data Sensitivity Tool (NDaST) and this process we name the half Monte Carlo method (HMM).

This study achieved multiple advantageous results: primarily, it will help us perform neutron activation analysis. Next, it will give us the opportunity to produce radio-elements with short half-lives. Am-Be single and multisource (5 sources) experiments were performed within an irradiation facility with a paraffin moderator. The resulting models mainly increase the thermal neutron flux compared to the traditional method with water moderator.

This paper presents a Monte-Carlo code to simulate the time sequences of the β-decay following implantation of a continuous radioactive ion beam into a segmented silicon detector. We extended our simulation to the β-delayed neutron process. An analysis procedure, which has been developed to obtain simultaneously the β-decay half-life and the β-delayed multi-neutron emission probability, was verified by the simulation data.
