Optical Characterization of Micro Particles in Molecular Plasmas
Abstract
This report results from a contract tasking University of Cambridge as follows: Understanding the role of nano and micro sized particles in industrial processes and in the atmosphere using plasmas has become very important. The grantee proposes to develop a novel, sensitive and non-invasive diagnostic technique for probing the chemical composition of solid particle surfaces in dusty plasmas. Specifically, pulsed tuneable lasers will be used to excite whispering gallery modes (wgms) in individual silica microspheres trapped in a plasma crystal. This novel chemical probe will link the particle composition to the chemical composition of the plasma.
