Available in PDF, EPUB and Kindle. Book excerpt: A set of coaxial cathode tubes produced a plasma having the same characteristics as the plasma from a tubular hollow cathode. Measurements of the plasma characteristics by microwave interferometry, plasma sweeper, Langmuir probe, and measurements made with a new plasma tool--a plasma scanner--showed that the plasma is nearly completely ionized at 10 to the 13th power/cc ion density. The electron beam, originating in the cathode, was detected by means of the scanner. The electrons in the beam attain energies as high as two-thirds of the arc voltage drop. The ion temperature of 6.9 electron volts, which was deduced from plasma sweeper measurements and diffusion theory, could result from directed ion drift; the electron temperature of the plasma is 3 electron volts.

Available in PDF, EPUB and Kindle. Book excerpt: The voltages, currents, and heat loads to a coiled anode and multi-element hollow cathode were determined. The cathode consisted of a flat water-cooled base element and five hollow, water-cooled disks in a vertical column above it. The cathode elements were insulated, and shunt resistors were used to cause the cathode current to split into six paths. The anodes were water-cooled coils of 1/4-in. diameter copper tubing. A convergent divergent shape was used with an air atmosphere, and a two row coil was used with argon. The coil current produced a magnetic field which increased anode life. The anode was mounted above the cathode, and the arc was not enclosed. When operated in air, the cathode sustained currents of 200-300 amperes before failure. Operation in argon was limited by constrictor failure to about 200 amperes. Cathode condition was very good after 40 test runs in argon at total currents ranging from 83 to 218 amperes. Calorimetrically measured heat loads decreased when the current split among the cathode elements and further decreased in an argon atmosphere. (Author).

This book was released on 1967 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: A one-meter coaxial-hollow cathode argon arc was investigated experimentally and the results obtained were compared with already-documented data on conventional-hollow cathode low-pressure argon arcs. The outer diameter and inner diameter of the hollow cathode, used for comparison purposes, were 1.91 and 0.953 centimeters, respectively, while the outer diameter of the coaxial cathode was 1.91 centimeters and its inner diameter was 1.27 centimeters. Radial profiles of the electron temperature and density in the arc plasma were measured by a Langmuir probe; current profiles were measured by an electrical profile scanner device. A plasma sweeper provided data on electron density. The data obtained by all methods for the low-pressure arc of the coaxial-hollow cathode were consistent in repeated tests and consistent with the data available on the low-pressure arc of the conventional-hollow cathode. The maximum electron temperature was 4.8 electron volts; the electron density average for the arc column was 3 x 10 to the 12th power per cu cm. With the coaxial arrangement for a cathode of any fixed dimensions, the coaxial type can be run at higher power than a conventional single-element hollow cathode of the same dimensions. (Author).
