Judith Bannon Snow is group leader of the High Explosives Science and Technology group at Los Alamos National Laboratory. This high explosives (HE) group consists of four technical teams: HE chemistry, HE physics, HE materials, and HE engineering. The group does "cradle to grave" explosives research that includes synthesis, formulation, chemical analysis, mechanical properties testing, micro-mechanical physics, nonshock initiation, deflagration to detonation theory, slow combustion, thermal studies, safety assessment, performance assessment, aging studies, and demilitarization of energetic materials. |

Prior to coming to Los Alamos, Judith was a program manager at the Naval Undersea Warfare Center in New London, Connecticut, where she directed the Marine Optics
Laboratory for ten years. She did experimental laboratory work in underwater laser
propagation for high data rate communication and in optical phase conjugation for
dynamic underwater image correction. Judith and the Marine Optics team built and
tested prototype laser detection and communications systems that were tested in
the field. Judith conducted a field test of the prototype laser warning detection system. The detector, along with similar prototypes from other DoD labs, was helicopter-mounted and its performance tested by irradiation with ground-based lasers at White Sands Missile Range. She also participated in Navy-sponsored underwater Arctic experiments. These experiments were conducted at a University of Washington ice camp, located on an ice floe 200 miles off the north coast of Alaska. Following laboratory and tank tests, Judith conducted high data rate underwater laser communications experiments at an underwater laser range off Andros Island, Bahamas. (See photos and related story in sidebar). Following the completion of her doctoral work in physical chemistry and laser spectroscopy, Judith was a postdoctoral fellow at Yale University in chemical physics where she did research on exciton migration in low temperature crystalline systems. Judith did nonlinear optics research in Applied Physics at Yale University for several years. Her research included multipoint coherent anti-Stokes Raman scattering for remote temperature measurement and nonlinear scattering in micron-size droplets. Droplets of ethanol doped with small amounts of dye behave like tiny spherical laser cavities. Irradiation of these droplets with green laser light produces intense red light from this "laser droplets". Judith and her coworker, J-B Zheng discovered that even in the absence of dye, plain water droplets irradiated with green laser light will undergo stimulated Raman scattering, emitting similar intense red light. She has two patent awards, as well as numerous scientific publications in laser spectroscopy, microparticle scattering, and nonlinear optics. In addition to earning a Ph.D. in chemistry from Wesleyan University, Judith was a Sloan Fellow at the Stanford Graduate School of Business, where she received an M.S. in management. Judith was invited by the National Academy of Sciences to serve on the National Research Councilšs Committee on Explosives Detection and Marking. This Committee was formed under a mandate of the Antiterrorism and Death Penalty Bill, passed by Congress in April 1996. Dr. Snow and the other Committee members were tasked to identify, evaluate and recommend technical solutions to the threat of terrorist use of explosives. In addition, Judith serves on the board of the Alliance for Photonic Technology, a consortium of Los Alamos National Laboratory, Sandia National Laboratory, Phillips Laboratory and the Center for High Technology Materials at the University of New Mexico.  |
