A hydrodynamic X-ray radiation source

The results of experimental investigation of a flow of a weakly conductive liquid in a coaxial channel with insulating walls are presented. The possibility of forming all the necessary conditions to generate X-ray radiation when liquid moves in the channel is shown. The questions of the electrization, the charge accumulation, and its discharge are considered. It is shown that the charge intensely accumulates during liquid cavitation in small holes on the channel wall. The appearance of stable luminous cavitation threads moving in the flow is revealed in the initial segment of the channel, and their role in the discharge of the cavitation regions is determined.
