Abstract
The conditions are investigated for gas breakdown above an Ni−Zn (M4OONN) ferrite surface. The assumption that the discharge is initiated by a thermal explosion of a surface layer of the ferrite modified by current flowing through it is verified experimentally and theoretically. The electric and thermophysical properties of the (ferrite+annealed layer) system are determined. The experimentally observed temporal characteristics of the prebreakdown phase of the discharge and the dependences of the breakdown voltage on the discharge-circuit parameters are described within the framework of a single model.
