Abstract: 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.

Abstract: A high voltage/high current electric pulse generator. Spark gap switches (E1, E2, E3) having a trigger electrode are connected to a trigger control circuit (CD). Switch (E1) is connected between the outer conductor of cable (C2) and an inner conductor of cable (C1). Switch (E2) is connected between the outer conductor of cable (C3) and the inner conductor of cable (C2). Switch (E3) is connected between output terminal (S) and the internal conductor of coaxial cable (C3). The outer conductor of cable (C1) is connected to ground and voltage source (SHT) is connected to internal conductors of the cables. The source charges cables (C1, C2, C3) in parallel when switches (E1, E2, E3) are off. A first ballast resistor (r) is connected between the first electrode and the trigger electrode. Load resistor (R6) is connected between the output terminal(S) and the external conductor of cable (C3). Resistor (R5) is connected between the outer conductor of cable (C 3) and the outer conductor of cable (C2).
