Franziska Treffert

Dr. Franziska Treffert is a postdoctoral researcher in the High-Intensity Laser High-Energy Density (HED) Science group at Lawrence Livermore National Laboratory. Her research is focused on the laser-driven generation of high-flux, directional neutron beams in a pitcher-catcher setup. Franziska received her PhD from Technische Universität Darmstadt (Germany) in January 2023 on high-repetition-rate laser-driven neutron sources employing cryogenic and ambient-temperature liquid jet as pitcher targets, where she received a prestigious PhD sholarship from the German Academic Scholarship Foundation awarded for two years. She conducted this research in collaboration with the HEDS division at SLAC National Accelerator Laboratory, where she was based throughout the duration of her PhD. 

During that time, she gathered experience collaborating on numerous experiments at XFEL and laser facilities in the US and Europe and lead two experiments at Colorado State University as part of LaserNetUS.
