Add to ORKGABSTRACT (Continue on reverse if necessary and identify by block number) A theoretical study and computer analysis of the cathode spot of a unipolar arc was conducted. The underlying theories of Plasma Physics, 4'Pace Carge Effects, and /liectron Lmission needed for an understanding of cathode phenomena are presented. Two models of unipolar arcing are reviewed and an analysis of the cathode spot is begun. A stationary model of the cathode spot is formulated with a system of equations that is not closed. A method of solution, using the Steenbeck Minimum Principle, is- ' 4 1ized and a computer program developed t
