The nanosecond generator RG-1 with near-rectangular pulse

The 300 kV, 17 Ohm generator RG-1 that can deliver the near-rectangular pulse with the pulse duration 80 ns FWHM is described in this paper. Polarity of output pulse can be changed by the simple switch. The fast capacities in the Marx generator are used instead the pulse forming line. The multispark gas switches have been developed to decrease the inductance of discharged circuit. The generator is supplied by the built-in high voltage source. The installed mini-computer controls its operation. It is used the power supply-line 220 V. The RG-1 can be used in different mode of operation: gas discharge, particle beam formation and so on.
