“…In [13][14][15][16][17][18] the authors analyze the magnetic field effect on the emission current. Blatt [13] theoretical examines a flat metal surface emitting electrons and external magnetic field normal to it.…”

“…The effect of the field on the emitted current is determined by a modified spectrum of conduction electrons. Blatt supposed that the penetrability of potential barrier at the metal-vacuum interface is independent of the magnetic field, which supposition was borne out in [15,16]. According to the current density formula given in [13], the emission current decreases in proportion to B 2 .…”

The subject of the present theoretical and experimental investigations is the effect of the external magnetic field induction on dark current and a possibility of breakdown. The generalization of the Fowler-Nordheim equation makes it possible to take into account the influence of a magnetic field parallel to the cathode surface on the field emission current. The reduction in the breakdown voltage due to the increment in electron-impact ionization was theoretical predicted.Experimentally shown that the presence of a magnetic field about a tenth as a large as the cutoff magnetic field [18] reduces the breakdown voltage by 10% to 20% for practically all cathodes no matter what their surface treatment.

The paper presents a study of the influence of nanovoids formed in the metal surface layer on the field emission current (the first stage of the accelerator structure breakdown). It is shown that the field emission current through nanovoids has a resonant character. It was found that under resonant conditions, an increase in the current density from the copper surface by more than 3.5 times compared to the case of an unmodified surface is observed. The presence of a dielectric in the nanovoids expands the resonant region. When the resonance conditions are not met or the diameter of the nanovoids increases, the current density decreases to zero, which can be a way to prevent an accelerator structure breakdown.
