A diffusion model for light scattering in ejecta
J. A. Don Jayamanne, J. -R. Burie, O. Durand +2
We derive a diffusion equation for light scattering from ejecta produced by extreme shocks on metallic samples. This model is easier to handle than a more conventional model based…

Characterization of ejecta in shock experiments with multiple light scattering
J. A. Don Jayamanne, J. -R. Burie, O. Durand +2
Upon impact, the free surface of a solid metal may eject a cloud of fast and fine particles. Photon Doppler Velocimetry (PDV) is one of the optical diagnostics used to characterize…
