Abstract

Space-charge-limited current conduction in a diode with an inhomogeneous gas concentration is investigated when gas density dependence on x can be described by the relation n(x)=Nδ (x−xB). It is shown that when the localized ionization attains its limiting pressure, two conditions are satisfied: the electric field intensity becomes zero at x=xb and the derivative of the electron current density with respect to pressure approaches infinity, i.e., two different criteria for igniting a controlled discharge used by various investigatore are simultaneously satisfied.
