Research Interests

Stephen Padgett began working at LLNL in May 2012 and currently works in the Safeguards, Nonproliferation, & Response group. Padgett’s research interests include beta decay, gamma-ray, and neutron spectroscopy studies for nuclear forensics and nuclear safeguards applications. His current job responsibilities involve experimental setups for thermal neutron irradiations at the McClellan Nuclear Research reactor as well as analysis of subsequent gamma-ray spectroscopy data from this and other experiments. He also performs Monte-Carlo simulations and data analysis for various forensics, safeguards, and basic nuclear science experiments. His previous work experience includes participating in neutron irradiations at the Nevada National Security Site for improving nuclear data as well as performing simulations for a project related to the Comprehensive Test Ban Treaty.
