Download or read book Spatially Resolved Temperature Determination in I2 Gas Using Doppler Limited Saturation Spectroscopy written by James W. Myers Jr and published by . This book was released on 2000-03 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: Saturation spectroscopy techniques were used to demonstrate the ability to make spatially resolved temperature measurements by exploiting the B3 Pil(O+(sub u)) - X1 Sigma(O+ (sub g)) electronic transition in molecular iodine (12). Doppler-free saturation spectroscopy measurements resulted in hyperfine spectral profiles for the P(7O) 17-1 and P(53) 19-2 ro-vibrational transitions between the electronic levels. Doppler-limited saturation spectroscopy, an adaptation of the Doppler-free technique in which beams propagate in the same direction and cross within the gas sample, allowed for the measurement of spatially resolved Doppler profiles for the same transitions. The profiles were measured at several spatial positions in 12 cells with measured temperature gradients. The technique did not produce accurate temperature readings; however, the saturation spectroscopy variant did produce profiles that were spatially resolved, with an interaction volume of approximately 12 x 1 x 1 (mm units). This thesis was motivated by the Air Force's Airborne Laser Laboratory (ABL), which has a need to discriminate a spatially distributed temperature distribution. The Chemical Oxygen Iodine Laser (COIL), which is the high power directed energy source for ABL, has a low concentration of 12 as a reaction byproduct. Line-integrated optical temperature measurements inside the COIL reaction chamber have been higher than predicted, which can have a dramatic effect on the threshold condition for the laser. Spatially resolved temperature measurements would provide a diagnostic tool to identify hot spots and heat gradients in the supersonic flow region of the laser.

Book excerpt: A laser induced fluorescence (LIF) technique for the detection of iodineis experimentally investigated as a potential on-line real-time monitor ofiodine-129 in nuclear fuel reprocessing plants. To avoid interference byNO2, attention is focused on the fluorescence excited by an ultravioletlaser operating near 250 nm, whose design and construction are described.Methods of enhancing the signal strength are considered, along withalternative laser monitoring schemes.

Available in PDF, EPUB and Kindle. Book excerpt: We studied the production and loss of IF (Iodine MonoFluoride) in our flow system using a laser-induced fluorescence diagnostic for measuring IF number densities. We related the production of F-atoms to the residence time of CF4 in the microwave discharge and found a yield of about 0.3 F-atoms per CF4 molecule under typical operating conditions. We identified flow conditions that produce complete reaction of CF3I in the injector and showed that a negligible amount of IF is destroyed in the injector under these conditions. Some loss of IF in the main flow tube was found at low flow velocities; however, this loss appeared to be negligible at higher velocities and permitted us to operate in a regime where IF number densities were directly related to the amount of CF3I flowing into the injector. We also found that operation of the injector using excess CF3I resulted in the deposition of an optically opaque thin film on the reactor walls. This required us to operate in excess F-atoms and eliminated the need to measure absolute F-atom number densities. Keywords: Iodine monofluoride; Electronic quenching; Electronic excitation; Energy transfer; Photon yields; R-centroid; Excited nitrogen; Vibrational relaxation; Transition probabilities; and Flow reactor.

Download or read book Techniques of Flow Visualization written by Wolfgang Merzkirch and published by . This book was released on 1987 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: The techniques of flow visualization and their application in wind tunnels, water channels, and experiments related to propulsion research are reviewed. These techniques can be classified roughly into three major groups: Surface flow visualization, scattering from flow tracers, and density sensitive flow visualization. The progress in laser optics and the wide-spread use of computers has led to the development of new techniques and evaluation procedures, which are included in the review; e.g. laser-induced fluorescence, speckle photography, image processing, and optical tomography. Emphasis is given to the discussion of the physical background of the methods. Information on technical details is provided by means of a number of sample photographs and by respective references.

Available in PDF, EPUB and Kindle. Book excerpt: Written by a team of pioneering scientists from around the world, Low Temperature Plasma Technology: Methods and Applications brings together recent technological advances and research in the rapidly growing field of low temperature plasmas. The book provides a comprehensive overview of related phenomena such as plasma bullets, plasma penetration into biofilms, discharge-mode transition of atmospheric pressure plasmas, and self-organization of microdischarges. It describes relevant technology and diagnostics, including nanosecond pulsed discharge, cavity ringdown spectroscopy, and laser-induced fluorescence measurement, and explores the increasing research on atmospheric pressure nonequilibrium plasma jets. The authors also discuss how low temperature plasmas are used in the synthesis of nanomaterials, environmental applications, the treatment of biomaterials, and plasma medicine. This book provides a balanced and thorough treatment of the core principles, novel technology and diagnostics, and state-of-the-art applications of low temperature plasmas. It is accessible to scientists and graduate students in low-pressure plasma physics, nanotechnology, plasma medicine, and materials science. The book is also suitable as an advanced reference for senior undergraduate students.
