Light Generation by the High-Intensity Carbon ARC
The theory of light production in the high-intensity carbon arc is discussed, together with a description of the phenomena associated with the initial striking of the arc and the maintenance of the electric discharge through the arc stream. The formation of the positive carbon crater is described and the factors defined which determine the maximum current loading which a particular carbon electrode will support. The importance of efficient heat dissipation from the positive crater region in extending the useful current range of a given-sized carbon is pointed out, and the effectiveness of water cooling in providing better heat dissipation at this point is noted.
