Production and Application of an
Aerosol of Micron-scale Particles

Tom Donnelly

Department of Physics, Harvey Mudd College

A device that uses ultrasonic atomization of a liquid to produce an aerosol of micron-scale droplets will be discussed. This device represents a new approach to producing targets relevant to laser-driven fusion studies, and to the relatively untested subfield of nonlinear optics in which wavelength-scale targets are irradiated. The device has also made possible tests of fluid dynamics models in a novel phase space. The distribution of droplet sizes produced by the device and the threshold power required for droplet production are shown to follow scaling laws predicted by fluid dynamics.

Refreshments at 4:00 PM. Seminar begins at 4:10 PM.
