Investigation of the Stability of Laser Discharges ( Book )
2 editions published between 1974 and 1975 in English and held by 4 WorldCat member libraries worldwide
Calculations indicate that thermal and/or vibrational instabilities will occur for most discharge conditions of importance in high power, cw carbon dioxide convection lasers. Computed characteristic growth times for these modes are typically on the order of 1 msec. The experimental investigations described herein have verified that it is the growth of disturbances in gas translational or vibrational temperature which is responsible for the discharge constriction observed in carbon dioxide laser plasmas. Moreover, because of the characteristic msec instability growth times, convection of the unstable portions of the medium out of the plasma region can effectively stabilize the discharge. The beneficial aspects of having homogeneous gas flow conditions and uniform electrical power deposition are suggested by the theory. Experimental results confirm that such plasma and fluid dynamic uniformity permits operation at increased electric power inputs and higher pressures. Extension of these results to CO lasers and electron-beam sustained plasmas is discussed

The Influence of Negative Ion Processes on the Stability of Molecular Gas Discharges ( Book )
1 edition published in 1974 in English and held by 1 WorldCat member library worldwide
Theoretical and experimental studies of negative ion processes and their influence on the stability of weakly ionized glow discharges have been conducted. Emphasis in these investigations has been directed toward analysis of gas mixtures in which negative ions are produced by dissociative electron attachment of CO2, CO, or O2. It is shown that attachment and detachment reactions normally occurring in discharges containing these species can significantly affect both the steady state and transient characteristics of the plasma, even when an external source of ionization is provided. The electron temperature dependence of the electron-molecule attachment coefficient is found to be particularly important in determining the occurrence of ionization instability.

Investigation of the Plasma Properties of High Energy Gas Discharge Lasers ( Book )
1 edition published in 1970 in English and held by 1 WorldCat member library worldwide
The report summarizes research directed toward determining the plasma properties and key processes governing the conversion of electrical energy in gas discharges with emphasis placed on electric discharges typical of CO2 lasers. A model has been formed from which the vibrational level population in CO2 and N2 in a gas discharge laser can be calculated. The model treats CO2 by dividing the CO2 populations into four groups of specific combinations of the vibrational quantum numbers. Since knowledge of the neutral gas temperature in a laser medium is extremely important in accessing laser performance, an attempt has been made to develop a method of measuring the neutral gas temperature. The study of the effect of gas mixture on the validity of the optical temperature measurement has indicated that there are conditions which result in curvature of the data presentation. To achieve greater insight into the details of discharge maintenance, an analysis of a wall dominated CO2 laser discharge column has been undertaken. In conjunction with the positive column analysis, a study was made of the importance of negative ion formation, multistep ionization, multiple ion species, recombination, attachment, electron detachment, and dissociation
Plasma properties in a thermionic converter ( Book )
1 edition published in 1964 in English and held by 1 WorldCat member library worldwide
The properties of the non-equilibrium plasma existing in the interelectrode space of the arc-mode converter were investigated with coaxial electrostatic Langmuir probes. Probe measurements were made as a function of cesium pressure, emitter temperature, interelectrode position and converter output in several low-temperature arc-mode converters. The plasma potential, was found to vary significantly across the interelectrode space. Both the existence of a retarding sheath for electrons very close to the emitter surface and a region farther from the emitter in which the variation in plasma potential is accelerating for electrons have been detected. Significant variations in the plasma potential existing in the space were observed with changes in emitter temperature, cesium pressure, and converter output. The electron energy distribution is non-Maxwellian with a significant number of electrons with energies in excess of 1.4 eV. However, from an analysis of the production and loss rates in the converter, there is an insufficient number of electrons, even in the accelerated electron energy distribution, to account for the enhanced degree of ionization observed in arc-mode operation by single stage electron-atom collisional ionization processes. Further analyses of the production and loss rates using the electron energy distribution indicate that ambipolar diffusion is the dominant loss process in the converter if the major ionic species is Cs(+). However, if the major ionic species in the converter is Cs sub 2(+), then recombination is the dominant loss mechanism. (Author)

Effects of inert gas overpressure on arc characteristics ( Book )
1 edition published in 1965 in English and held by 1 WorldCat member library worldwide
To determine the effect of the presence of an inert gas on the properties of the non-equilibrium cesium plasma which exists in the interelectrode space of an arc-mode thermionic converter, detailed electrostatic probe measurements have been made of electron temperature, electron number density, and the plasma potential over a wide range of inert gas pressures. By employing electrostatic probe techniques to measure the properties of the non-equilibrium cesium plasma, direct assessment has been made of the effects of an overpressure of inert gas on the plasma properties without having to include extraneous effects such as changes in the work functions of the emitter and collector produced by the interaction of the inert gas with these surfaces. In addition, spectroscopic measurements have been made to determine the behavior of the atomic and molecular excited state populations with changes in inert gas pressure, converter output and maximum electron density in the neutralization plasma. The range of inert gas pressure over which volume ionization processes can be sustained in the non-equilibrium neutralization plasma in the converter with argon used as the inert gas has been determined from these measurements.

Probe measurements in a cesium plasma converter ( Book )
1 edition published in 1963 in English and held by 1 WorldCat member library worldwide
Measurements of the properties of the plasma in the interelectrode space of both conventional and arc mode thermionic converters were obtained with coaxial electrostatic probes. In the high temperature cesium plasma present in the con verter, it was found that severe distortion of the probe current-voltage characteristic occurs due to extraneous current leakage to the probe and thermionic emission from the probe tip. By means of techniques previously reported, these distortions were eliminated by employing a coaxial-type probe. A comparison of probe in formation is made to models of both types of converter. In the conventional mode of oper ation the measured electron energy distribution is Maxwellian with a temperature of 0.18 ev which corresponds closely to the emitter tem perature of 0.12 ev. In the arc mode converter, probe studies indicate that the electron energy distribution is non-Maxwellian with two energy groups existing in the plasma. The high-energy group of electrons corresponds closely in energy to emitter electrons which were accelerated by potentials comparable to emitter sheath po tentials. The lower energy group corresponds to electrons which are essentially in equilibrium with the cesium vapor in the interelectrode space of the converter. (Author)
