Study of Chemiluminescent Reactions of Metal Atoms ( Book )
1 edition published in 1977 in English and held by 1 WorldCat member library worldwide
Laser vaporization of thin metal films has been used as the metal atom beam source for the study of chemiluminescent oxidation reactions. Techniques have been developed and demonstrated to experimentally determine the chemiluminescent reaction stoichiometry, the relative chemiluminescent cross section vs. kinetic energy, the total scattering cross section vs. kinetic energy, the total reactive cross section (under favorable conditions), the chemiluminescent spectrum and radiative lifetimes of chemiexcited species with lifetimes in the approximate range 10-100 micro sec. The versatility of the laser vaporization metal beam source has been demonstrated by obtaining the chemiluminescent spectra for the N2O oxidation of twenty different metal atoms under essentially identical experimental conditions. A definitive measurement of a long lived chemiexcited state has been made for the Pb + N2O reaction; screening tests on Sn, Mo, and Ge oxidation by N2O suggest these reactions also produce long lived excited states.

Chemical Reactions Kinetics with Metallic Atoms ( Book )
1 edition published in 1972 in English and held by 1 WorldCat member library worldwide
The report describes research to develop a pulsed atomic beam by the laser vaporization of high velocity microparticles and to use the pulsed atomic beam to measure several metal monoxide formation cross sections. An experimental system for irradiating high velocity particles was designed, built, and tested. Tests confirmed that the particles were vaporized by the laser bombardment, but the thermal (random) velocity distribution of vaporized atoms and ions resulted in a much lower than anticipated useful beam intensity. As an alternative approach, the laser bombardment of solid metallic targets was used to produce both ionic and atomic pulsed beams. Useful beam intensities were obtained for both ions and atoms of uranium, thorium, aluminum, and iron. Generally, the entire energy spectrum was present in each pulse. Using time-of-flight techniques to specify the incident beam energy, cross sections for the reactions U(+) + O2 to UO(+) + O and Th(+) + O2 to ThO(+) + O were measured. (Author)
Ramo-wooldridge general research program, 1959. b. artificial meteors ( Book )
1 edition published in 1960 in English and held by 1 WorldCat member library worldwide
A report on the research done on electrostatic acceleration of charged particles is presented. The technical aspects of accelerating ballistic projectiles by electric fields and the operation of a 120 kv accelerator were discussed in previous reports. It was demonstrated that particles having dimensions of a few microns could be efficiently accelerated to 2 km/sec or so at modest voltage levels
Advanced Laser Concepts ( Book )
1 edition published in 1976 in English and held by 1 WorldCat member library worldwide
The major goal of the Advanced Laser Concepts contract is directed towards the understanding and development of chemically pumped electronic transition lasers. The program is divided into two separate tasks which use two approaches towards achieving the common goal. The first task is entitled Chemistry of Excited States. The approach used for this task is the investigation of the possibility of producing a chemically pumped visible or ultraviolet laser by means of chemically producing a metastable excited species which subsequently transfers its energy to a lasing species. The second task is entitled Molecular Beam Studies. The approach used in this task is to explore and screen a number of species as potential candidates for chemically pumped electronic transition lasers. The central experimental tool is a pulsed, high flux molecular beam apparatus
Chemical Laser Reactions Cross-Section Measurements ( Book )
1 edition published in 1974 in English and held by 1 WorldCat member library worldwide
The objective of the program was the measurement of energy-dependent cross sections for each of the final vibrational states of the DF molecule resulting from the reaction F + D2 yields DF* + D. In pursuit of this objective, a powerful new technique for the detailed study of gas-phase chemical reactions was developed. The high-intensity atomic beam is produced by the irradiation of thin films of solid material with a Q-switched ruby laser pulse. For example, the flux of 4 eV fluorine atoms produced by the irradiation of a BiF3 film with a 1/2 joule laser pulse has been estimated to be 10 to the 17th power atoms /sq cm-sec at a point 60 cm from the laser target. The experiment used a crossed beam configuration where the fluorine atom beam interacts with a deuterium gas beam obtained from a nozzle source. The method of detailed energy balance was to be used to determine the internal energy state of the product molecules. Two approaches to achieving the required energy discrimination were evaluated: One involving the use of a velocity-dependent product detector and the other using mechanical velocity selection of the incident beam.

Development of High Intensity Ion Sources ( Book )
1 edition published in 1974 in English and held by 1 WorldCat member library worldwide
This report summarizes the progress made on an experimental program designed to provide data that will permit a reliable estimate to be made of the aluminum monoxide (AlO) concentration in the debris patch subsequent to a high altitude nuclear burst. The technique used in the experiment involves firing a laser beam at an aluminum target. The resultant aluminum plasma is electrostatically accelerated to high energy and injected into a laboratory tank for subsequent measurements
