Abstract
The impedance associated with oxide cathodes under active conditions is well known. Values as high as 100 Ω/cm 2are reported. The impedance usually consists of the direct resistance of the oxide layer and a contribution from the interface and its capacity. The impedance is known to change with time, particularly when the valve is operated in the cut-off state. In this paper the resistance of dispenser cathodes is measured.
