A Modified Version of the Grimm's Glow Discharge Lamp for Use as a Demountable Hollow Cathode Emission Source. II. The Current Intensity-Voltage Characteristic Curves

The dependence of resulting voltage on applied current intensity in a modified commercially available hollow cathode lamp is determined in the case of aluminium, copper and graphite cathodic materials in an extended range of argon carrier gas pressures and for five different cathode - anode distances. Experimental results show that the modified emission source affords high stability discharge in a wide range of experimental parameters.
