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…
