Available in PDF, EPUB and Kindle. Book excerpt: 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).

Available in PDF, EPUB and Kindle. Book excerpt: An investigation was directed toward obtaining an improved understanding of the properties of the cesium neutralization plasma existing in ignited-mode thermionic converters. Toward this end an analysis was made of electron and ion transport phenomena based on conditions known to exist in thermionic converter plasmas. In support of this analysis, detailed measurements of electron density and temperature in the ignited-mode converter plasma were made using high resolution spectroscopic techniques. With this information, quantitative estimates were made of: the electric field intensity, the electron kinetic energy flux, the ion current density, and the charged particle production rate. On the basis of these results, an interpretation was made of the role played by the cesium neutralization plasma in determining converter performance. (Author).

Book excerpt: The book details sources of thermal energy, methods of capture, and applications. It describes the basics of thermal energy, including measuring thermal energy, laws of thermodynamics that govern its use and transformation, modes of thermal energy, conventional processes, devices and materials, and the methods by which it is transferred. It covers 8 sources of thermal energy: combustion, fusion (solar) fission (nuclear), geothermal, microwave, plasma, waste heat, and thermal energy storage. In each case, the methods of production and capture and its uses are described in detail. It also discusses novel processes and devices used to improve transfer and transformation processes.
