    Abstract

    This paper presents the design and testing results for a generator of bipolar voltage pulses of amplitude ±200 kV, duration ∼3.5 ns, and repetition rate up to 100 Hz across a 12.5-Ω matched load. The mode of multichannel switching of spark gaps with subnanosecond time delays between the operation of the channels has been realized. A numerical simulation of the generator operation has been performed with its design represented by homogeneous lines and with the parameters of spark gaps described in terms of the Felsenthal-Praud criterion for the breakdown delay and by the Rompe-Weitzel spark model. It has been demonstrated that mixtures of ordinary and inert gases as well as hydrogen show promise as fill gases for spark gaps to reduce losses. The generator is intended to excite wideband transmitting antennas.
