| Abstract: | An arrangement is described for generating at various pressures a filamentary, axially symmetric thermal arc of high stability. The arc's composition is wholly determined by the initial composition of the gas used. The radial temperature distribution of the arc in air was studied over the pressure range from 0.26 to 6 atm. At a current of 10 amps., the temperature in the axial region of the arc in air varies between 15 000 and 20 000° K, depending upon the pressure. At a distance of 0.4–0.5 mm from the axis of the discharge, the temperature drops to 5000° K.In conclusion, the authors wish to express their sincere gratitude to M. A. El'yashevich for his interest. |
