Solar Plasma Propulsion
Abstract
The simultaneous measurement of absorption and emission spectroscopy is proposed to enable quantitative determination of the performance of a gaseous plasma solar energy receiver. Production of an experimental spectroscopy data base of species composed of hydrogen and selected Group 1 elements (the alkali metals) and Row 2 elements (carbon, nitrogen, and oxygen) approaching conditions heretofore unattained in a static gas spectrometer cell, 3000 K and 100 atmospheres, is the principal objective of the project. Preliminary design specifications for a spectrometer cell with automated flow control, pressure control, and plasma composition control are worked out in this interim report. The window to window distance of the cell is ten to fifteen inches and the optical path is one to three inches.
