Ferromagnetic spiral in permanent magnetic field and its application

The creation of pulse transformer at high voltages is an important technical problem. In the paper it is shown that using a spiral made of ferromagnetic material, e.g electric steel ''Armco'' in the longitudinal magnetic field, the pulse voltage can be multiplied. This multiplication is described well by the empirical expression V=V₀e^μn, where V is the multiplication of pulse voltage on the spiral turn, V₀ is the pulse voltage applied from the capacitor battery. From the side of the grounded part of spiral the ''white'' radiation is emitted being connected with plasma glow. Plasma is created by an intensive electron flux. The electrons are generated as a result of a cold explosive emission in the spiral turn. Their current is of the order of 30 kA. The spiral emits the high-frequency radiation at the distance of 30 cm from the spiral and is of the order of 20.5 kV. A source of pulse X-ray radiation, X-ray laser, as well as tiny electron accelerator, can be created. (author)
