A Marx generator, includes a number of capacitors (E) connected in series via spark gaps (E), between two output terminals and a power supply circuit that charges the capacitors in parallel. The capacitors are connected in series by a flat line formed of two metal strips running parallel and facing one another. These strips are connected together electrically at one end of the line and respectively to the output terminals at the other end and consist of one continuous strip and a second strip subdivided by transverse slots into successive plane sections interconnected in series alternately by a capacitor and a surface spark gap. A structure of this kind reduces the inductance of the generator and hence improves the rise time of the output pulses.

High voltage/current pulse generator using spark gaps

Intense soft X-ray source having an enclosure filled with gas and having two electrodes connected to a high voltage source, one of the electrodes having an opening. A device is provided for producing a photoionizing radiation directed through the opening. The radiation traversing the gas in the direction of the other electrode and during its passage producing a plasma microchannel, an electrical discharge supplied by the source then occurring in the microchannel, wherein the device for producing the photoionizing radiation is an auxiliary soft X-ray source.
