This book was released on 1977 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: A hyperthermal molecular beam apparatus, utilizing a heated seeded supersonic nozzle capable of producing fast intense beams of atmospheric species, has been employed to study vibrational excitation of plume species carbon dioxide and carbon monoxide. The apparatus is provided with a novel neutral beam detector for measurement of beam intensity and velocity distribution. The excitation mechanism is studied through monitoring of the infrared emission from the plume species by the use of lead sulfide, lead selenide, and indium antimonide. Lack of measurable signals is analyzed in terms of signal to noise ratios and it is shown that excitation cross sections generally have an upper limit of 10 to the 19th power per square centimeter showing that transfer of translational energy into internal energy does not take place efficiently.

This book was released on 1983 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: The measurement of absolute excitation cross-sections of the asymmetric stretch mode (001) of H20 and C02 for collisions with atomic oxygen is important in understanding the signatures of high-altitude rocket plumes. Experiments are performed in a crossed molecular beam apparatus in which a CVF detector measures the collisionally-induced infrared fluorescent signal. Calibration and testing of the atomic oxygen source was completed. It was installed into the crossed beam apparatus and vacuum tested in preparation for performing the excitation cross-section measurements. Upper limits have been established for the excitation cross sections for the systems 0 + C02 and Ar + C02. The values determined are 0.03A squared for 0 + C02 at 3.85 km/sec and 0.003 A squared for Ar + C02 at 2.27 km/sec. Monte Carlo trajectory analysis of the data provides accurate correction factors to the raw data that account for kinematic and experimental constraints inherent in these measurements. It further shows that measurements near threshold cannot be used to determine the functional energy dependence of the cross section. Further modifications and improvements in the experimental approaches to improve sensitivity will be discussed.
