The influence of vaporization upon the roots of a high current arc. Pt. 2
Description
The root of an argon arc was stabilized by strong cooling of the graphite cathode; both the composition and the temperature of the plasma at the arc root were determined spectroscopically. The measurements of the absolute intensities of two CI and two CII lines revealed that the plasma is composed almost entirely of atomic carbon. Immediately in front of the cathode a temperature of 12 000 K was measured and the degree to which the gas was ionized was found to be 30%. The velocity of the plasma was 300 m/s. (orig.)
Abstract (German)
Der Ansatzpunkt eines Argonlichtbogens wurde durch starke Kuehlung der Graphitkathode stabilisiert. Zusammensetzung wie Temperatur des Plasmas am Bogenansatzpunkt wurden spektroskopisch bestimmt. Messungen der absoluten Intensitaet von zwei CI- und zwei CII-Linien haben gezeigt, dass das Plasma fast vollstaendig aus atomarem Kohlenstoff besteht. Unmittelbar vor der Kathode wurde eine Temperatur von 12 000 K gemessen; das Gas erwies sich als zu 30% ionisiert. Die Plasmageschwindigkeit betrug 300 m/s. (orig.)Additional details
