“…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.
