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…

Recovering particle velocity and size distributions in ejecta with Photon Doppler Velocimetry
J. A. Don Jayamanne, R. Outerovitch, F. Ballanger +11
When a solid metal is struck, its free surface can eject fast and fine particles. Despite the many diagnostics that have been implemented to measure the mass, size, velocity or tem…

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…
