Bayesian Analysis Applied to Neutron Activation Diagnostics Measurements of MagLIF Experiment

Neutron activation diagnostics are commonly used to infer neutron yields in inertial confinement fusion experiments (ICF). At Sandia’s Z-Facility, ICF experiments using the Magnetized Linear inertial Fusion (MagLIF) concept are being conducted and activation diagnostics are employed to infer neutron yields. To infer neutron yields from the activation measurements, radiation transport modeling is relied upon to correct for scattering and attenuation present in the experiment that modifies the activation. To understand the likely error involved in those corrections Bayesian methods are used on inferred neutron yield data from a recent MagLIF experiment.
