摘要：For use in vacuum between a cathode (21) and an anode (23) with avoidance ofsurface flashover resulting from a voltage supplied between the cathode and the anode,a dielectric spacer (25) has a side surface and a projection (27) protruded perpendicularlyof the side surface. The projection has a length of projection from the side surface, acathode side end having a cathode distance relative to the cathode, an anode side end,and a thickness having a center plane between the cathode and the anode side ends andnearer to the cathode than to the anode, a ratio of the length of projection to thecathode distance being not less than 0.4. The cathode comprises no protrusion in a faceto face relation to the anode side end. It is possible to use the dielectric spacer betweentwo electrodes supplied with an AC voltage.
