Laser Induced Fluorescence detection of C2 and C3 Vapor
EMSL Project ID
2230
Abstract
The purpose of the experiment is to try and determine the feasibility of in situ laser diagnostics for erosion in carbon-based ion thruster grids for NASA. The experiment is designed to try and determine the lowest experimentally detectable amounts of C2 and C3 vapor detectable by LIF. The laser beam will pass through a slotted tube at elevated temperature (~2000 C). Vapor pressures of C2 and C3 as a function of temperature are well-known in this region. Since these are molecular transitions, they will be quite broad and variable given different temperatures. I need some basic data to begin estimating the limits of this process. Most of the literature references have not pushed the lower limits of detectability in these species. I am working right now to perfect a portable cell to bring down for these tests.
