Abstract:
A new method of low-impedance rod-pinch diode formation has been proposed and used. With this approach, the rod-pinch diode is preliminarily shorted by a thin radial foil. A low-impedance diode is formed when the foil, accelerated by current of a high-current generator, is detached from the anode rod. It is established that a series of sequential current closures via plasma of the foil and rod in this configuration can be used to obtain a train of short hard X-ray pulses.
