Abstract : Light or infrared sources in the 1 to 10 megawatt power range are usable for a variety of listed military and nonmilitary functions. The carbon arc source appears to be less limited physically, in terms of ultimate continuous power output, than the high pressure arc. The carbon arc is also more efficient. A review of the history and characteristics of various sources bears out these conclusions. Experiments were performed with 300-kilowatt and 700-ampere carbon arcs. Carbon powder was injected into the 700-ampere arc. A set of modifications on carbon ac technology are suggested in order to develop a 1 to 10 megawatt carbon arc requiring no mechanical anode rod feed. Alternating current magnets can be used to scan stabilizing fields and specially compounded anode materials contribute to quietness of the arc. (Author)
