“…The 50% energy part of this radiation is fairly hard-the corresponding energies of photons are higher than 1 keV. The brightness of this radiation significantly (by more than an order of magnitude) exceeded the brightness of the radiation of the ferrite surface measured in [1,2].…”

“…The current flow path on the ferrite surface was set by a pattern drawn with a graphite pencil. This path was generally the same during consecutive discharges in the experiment [1,2]. The generator load was unmatched, and its impedance varied greatly during the pulse.…”

“…In the studies of vacuum ultraviolet plasma radiation in a highcurrent discharge on a ferrite surface [1,2] a low-divergence short electromagnetic pulse was detected at the initial stage of the discharge. The 50% energy part of this radiation is fairly hard-the corresponding energies of photons are higher than 1 keV.…”

For the first time observed that at the initial stage of a high-current discharge, a low-divergence short (< 2 ns) electromagnetic pulse is formed over a ferrite surface. The 50% part of this pulse lies in the region of fairly hard x-ray radiation (hν >1 keV) with an energy ∼0.6 mJ and an average power 0.3 MW. The radiation propagates parallel to the surface in the anode direction with the angle divergence < 2°. The high directionality of the radiation in absence of the aperture-limiting devices for the radiation beam and the quadratic dependence of the spatial radiation energy flux density on the working part of the ferrite prism points to the coherent nature of the observed radiation. A possible generation mechanism of the radiation is proposed. It is based on the short-lived magnetization of the unit areas on the ferrite surface by a high-power electromagnetic pulse and subsequent coherent interference of the unit waves irradiated by these areas.

“…Radiation above ferrite surface in pulse discharge along it was researched in many works, such as, for example, [1][2][3][4][5]. However, only in [6] properties of radiation directed along the discharge on BIN experimental setup [1,6] were studied. In [6] a short (~2 ns) directional (~3 o -5 о ) X-ray (> 1 keV) pulse was observed during the pre-discharge stage, with pulse intensity increasing as square of the discharge gap length.…”
