Alumni Focus

Amanda K. Davis earned her B.S. degree in Engineering Physics from the University of Arizona in 2012 and was supported by a Frank J. Horton Fellowship from the Laboratory for Laser Energetics during her graduate education at the University of Rochester. She received her Ph.D. in Physics in 2017 with the thesis, "Laser Ablation and Hydrodynamic Coupling in Direct-Drive Inertial-Confinement-Fusion Experiments." For her thesis experiments (carried out on the Omega Laser Facility with her thesis supervisors Prof. D.H. Froula and Dr. D.T. Michel) she used time-gated images of the x rays emitted by directly driven capsules to experimentally study the hydrodynamic coupling of laser energy to the target. The mass ablation rate, the target trajectory, the laser absorption, and the conduction-zone length were simultaneously measured in spherically symmetric (1-D) implosions and compared to computer simulations. Her measurements highlighted the need for improved understanding of cross-beam energy transfer (CBET) in direct-drive implosions. Upon graduating, Dr. Davis accepted a one-year position as an NNSA Graduate Fellow, and is currently a Staff Scientist at the Johns Hopkins University Applied Physics Laboratory.
