Μeasurements of Sn Ejecta Particle-Size Distributions Using Ultraviolet In-line Fraunhofer Holography

Sn ejecta particle-size distributions from the break-up of a microsheet in a vacuum will be presented. The micro-sheet was created from a high explosive driven shock wave passing through a precision groove machined into a Sn sample. The particle-size measurements were carried out using an ultraviolet in-line Fraunhofer holography diagnostic. In conclusion, the diagnostic will be presented along with particle-size distributions over most of the ejecta velocities throughout the microsheet.

Ejected particle size measurement using Mie scattering in high explosive driven shockwave experiments

In this paper, we report on the development of a diagnostic to provide constraints on the size of particles ejected from shocked metallic surfaces. The diagnostic is based on measurements of the intensity of laser light transmitted through a cloud of ejected particles as well as the angular distribution of scattered light, and the analysis of the resulting data is done using the Mie solution. Finally, we describe static experiments to test our experimental apparatus and present initial results of dynamic experiments on Sn targets. Improvements for future experiments are briefly discussed.
