Abstract

Experimental results of breakdown voltages and V-I characteristics measured for the first time using coaxial cylindrical electrodes over the pressure range 0.006-0.72 kPa in sodium, potassium, cadmium, and zinc vapors are reported. The breakdown voltages in all the vapors are found to obey Paschen’s Law. The breakdown voltages in cadmium and zinc are substantially higher than those in alkaline sodium and potassium, directly in relation to their ionization potentials. The investigations also reveal that the V-I characteristics are pressure dependent and do not exhibit any negative current growth.
