TitleApplied Plasma Physicist/Engineer
Dr. Schmidt joined LLNL as a postdoctoral researcher in 2011 and then joined the staff in 2013. As a postdoc, she was involved in electrical grid research as well as modeling a short-pulse neutron source, the dense plasma focus (DPF). She performed the first kinetic modeling of a DPF, demonstrating that a particle approach was needed to correctly capture beam formation and neutron yield. She is now leading several projects in DPF research that have both modeling and experimental components. She is also a group leader for Engineering’s accelerator group.
Kinetic modeling of plasmas, dense plasma focus, neutron sources, radiation sources.
