Abstract

A thermionic converter with developed planar electrode surfaces is designed and tested. One of the electrodes has concentric circular grooves cut into its surface, while the other electrode surface is smooth. The grooves are 0.5 mm deep and 0.5 mm wide, having lands that are 1.0 mm wide. The experimental setup is flexible so that either the smooth or developed surface electrode can be operated as the emitter, with the other operating as the collector. The I-V characteristics and power output are compared for the two electrode arrangements. {copyright} {ital 1997 American Institute of Physics.}

Preliminary investigations of thermionic converters utilizing HOTEMA and DFVLR electrodes

Technical Report Saunders, M; Danielson, L; Huffman, F

Experiment results obtained from three thermionic converters using improved electrodes are reported. Two converters with ZrO/sub 2/-Mo cermet electrodes produced by a low pressure plasma spray technique at the DFVLR in Stuttgart were fabricated and tested. The first of this pair of diodes was outgassed and operated at high temperatures and did not show improved thermionic performance. The second of the two was outgassed and operated at more moderate temperatures. An encouraging barrier index of 2.00 eV at T/sub E/ = 1400/sup 0/K was recorded. Additionally, pre- and postoperational diagnostics confirmed that elemental concentrations on the emitter were nearly equalmore »« less

Experiments with enhanced mode thermionic converters. [With auxiliary electrode]

Journal Article Oettinger, P; Hussman, F - IEEE Trans. Plasma Sci.; (United States)

Reduction of the ionization and scattering losses associated with ignited mode cesium diodes is essential for high thermal-to-electrical conversion efficiency. Use of an auxiliary electrode in conjuction with a noble gas in the interelectrode space should permit more efficient ion generation for space charge neutralization. The characteristics of a thermionic triode utilizing a ring electrode and a dispenser cathode emitter have been studied as a function of xenon pressure, cesium reservoir temperature, spacing, electrode temperature and pulse parameters (i.e., potential, duration, and repetition rate) applied to the auxiliary electrode. Pulsed operation significantly enhanced output power with uniform discharges appearing tomore »« less

Analysis of emitter material transport in thermionic converter

Journal Article Paramonov, D; El-Genk, M - AIP Conference Proceedings

Output power and efficiency of a thermionic converter depend on temperatures, cesiated work functions, and emissivities of electrodes as well as the interelectrode gap size. Operation lifetime of a thermionic converter is directly related to the values as well as the stability of these parameters, which can be seriously altered by the transport of emitter material to the collector during operation. Loss rate of tungsten, a preferred emitter material, by sublimation at typical operating temperatures is small (about 3{times}10{sup 7} atom/cm{sup 2}sec at 2000 K). The loss rate, however, can be several orders of magnitude higher in the presence ofmore »« less

Development and evaluation of directionally solidified Cermet electrodes for thermionic energy converters

Conference Wolff, L; Danielson, L; Gubbels, H; ... - Proc., Intersoc. Energy Convers. Eng. Conf.; (United States)

At Eindhoven University of Technology, the high temperature materials research group HOTEMA is currently developing a new type of emitter electrode for thermionic energy converters. These Cermet electrodes consist of a refractory metal substrate coated with a directionally solidified metal-ceramic eutectic. In a joint research program, emitter materials produced in Eindhoven are evaluated by Thermo Electron in Waltham. A research diode incorporating a directionally solidified Mo-Al/sub 2/O/sub 3/,Cr/sub 2/O/sub 3/ Cermet emitter was build and tested. This converter exhibited stable performance at emitter temperatures up to 1650K. The barrier index at T /SUB E/ = 1400K was 2.04 eV. Minimummore »« less
